Hi, I have a problem with mi redmi note 7 (lavender)
the problem is that the wifi gets disconnected at some distance (something normal from redmi note 7) the real problem is that it doesn't reconnect, even if i have the router with me, in the lower area of the wifi it shows the message "saved" i try to forget the network and reset the password but i still can't connect, I have to restart the phone to be able to connect normally, but after a while the problem returns.
I'm using a custom rom called AOSIP with android 10, I have already used pixel experience, Crdroid, Evolution x, Havoc os and absolutely, all have the same problem. I want to make it clear that I have already used android 10 on my redmi note 7 (pixel experience) and I didn't have any problems, the problem started after the February updates this year.
I don't think it's a hardware problem because going back to miui or a custom rom with android 9 solves the problem.
I would like to know if you already know about this subject or if you are already working on it or if there is a solution.
thanks
here are some links of the captures I made

I think you might be onto something. In my case, the problem has been with Wifi Tethering. The phone is basically unusable as a hotspot, cutting out frequently and randomly and I think this has something to do with your wifi problem, maybe a driver issue? Like yourself, I've tried several aosp roms, all have the same problem.
Do you recall the last Pixel Experience release without this wifi issue? I am considering rolling back...

Good morning, I've already tried the most recent version of pixel experience, in fact the AOSIP rom is from May 17, 2020, practically yesterday.
Obviously it's a driver problem, but I don't understand why all custom roms have the same problem and I don't know how to solve it either (in android 10)

Could you tell me what rom are you currently using?
Could you also tell me the release date of the rom?

Currently on StagOS May 11 build. I settled on that after trying Pixel Ex, Evolution, etc as it was the one with the least hotspot issues; which isn't saying much as tethered devices would randomly lose internet connection while the phone clearly had internet and you could browse on any browser on the phone.
Since you say the issue occurred for you after the February updates, maybe you could point me to the last stable build you used so I can roll back.

I recommend all the versions that are from February, I would like to use pixel experience from that date but the page only has recent versions.
if you want a specific version use Crdroid 20200209
crdroid if you keep your old versions in the cloud so I recommend it, but I can not guarantee that it is totally stable. Pixel experience if stable but they don't have the versions of those dates.

I would like you to install the most recent version of pixel experience and when configuring the wifi, you will move away from the router until the signal goes away and try to connect again, just to check if it is really my phone or not.
Obviously making a backup before and also doing all this is optional. If you don't want to do it there is no problem thanks.

I already tried StagOs, I still have the same problem with the wifi, I also tried the hotspot and as you say if there is a data problem and in general it is unstable.
I downloaded the latest version of pixel experience and as expected the wifi was still failing, but the hotspot was working correctly so you can install it without any problem.

Okay sorry for the delay, been busy experimenting. Your recommendation of the Feb 09 crdroid build was spot on, flashed it, wifi and hotspot works like a dream, no issues at all.
After confirming that I decided to take a backup and try a recent AOSP build. I had already tried the Pixel Ex May 11 build and had the same issues so I downloaded the most recent build of Evolution X (May 17) and flashed.
So far, (Fingers crossed) I have not been able to replicate your WiFi issues or my tethering issues. WiFi did not disconnect even at a distance of over 50ft from the router. Keep in mind that these connection issues occur randomly but there's been nothing so far.
I will continue to use this build and test for the rest of the day. If I experience any dropouts I will restore to the stable crdroid build. Maybe you should try the newest evolution or go back to the stable crdroid to test if the issues are software related or specific to your device.
At this point I've been testing the latest build of Evolution (May 17) for about half a day, and zero problems so far, very stable.
I recommend you try it, may fix your wifi issues.

I am very happy that I found a solution to your problem, then I made some tests by creating an access point with my sister's phone ( xiaomi mi a1 ) and I performed the distance test and my phone connected normally. After several tests I am reaching a preliminary conclusion that there is an incompatibility with my router, I would need more tests with another router to conclude that my router is practically obsolete. That would also explain why I haven't found another thread with this same problem
good luck, tell me if you have finally solved your problem

After flashing CM6.1 I got the notorious wifi connectivity issue that numerous people have been reporting around the web. The issue is the following:
1: Wifi discovers neighbor's AP but no longer home AP.
2: Wifi problem randomly fixes itself, but sometime comes back and home AP can't be found again.
Many random solutions on the web include removing all stored AP's on the phone, resetting the router, rebooting and power cycling the phone numerous times, etc. Most people report that wifi miraculously start working again after the above but there is no consistency to exactly why and what works.
I tried all of the above with no luck, and even flashed three different roms with different kernels, did wipes, formatted everything inculding boot partition etc.
Here is the ACTUAL problem:
Different regions use different wifi channels. North America uses the first 11, most of the world uses 13, and Japan uses all 14. After flashing CM6.1 it changed the regulatory domain on the phone to only scan the first 11 channels meaning my European router broadcasting on 13 wouldn't show up. This setting seems to be persistent and doesn't change just because a new rom is flashed.
The reason people report the problem to be randomly fixed after a few days (and sometimes coming back days later) is because most routers automatically select which channel to broadcast on and therefore might end up within the first 11 at occasion. If it changes to something higher after that however, the problem is back.
Solution:
Open Settings, Wireless & network settings, Wi-Fi settings. Press "Menu" and select Advanced. Press regulatory domain and change to 14 channels.
To learn more about this and understand which channels are used in which countries, look here: http://en.wikipedia.org/wiki/List_of_WLAN_channels#2.4.C2.A0GHz_.28802.11b.2Fg.2Fn.29
Thanks man, even I still met an issue which was wifi disconnect frequently (usually after 12 seconds or less, it's re-scanning AP and trying to re-connect again) when I was trying to share my broadband internet from laptop to my legend.
BUT, after I update my wlan driver (now using 8.0.0.238 for my Atheros AR5XXX), the issue seems gone.
I found that by updating wlan driver to the very latest driver (for mine is 9.2.0.xxx) is not a guarantee to resolve this problem.
Now, by combining your suggestion and an "appropriate" driver version for my wlan, it work flawlessly until now
PS: driver version which will work varies from devices to devices. Do trial and error if you must
edit: well, not 100% gone, but much better . the connection is far more stable
Could be a problem for some but not all the issues with WiFi. I knew about this and even posted one or two times this check for the number of channels in different other topics as a possible solution. Still there are times when the connection to the "home" AP is done very late after entering in range or switching on the WiFi and the signal is changing from none to full and back frequently, for the same relative position to the router (I'm standing in the same place). Also even if the signal is full or good, the Legend seems not to have Internet connection that is, the weather updates or XDA applications or browser could not connect. This is still happening even if the selection for the number of channels is correct. And also this is not happening with a stock ROM, I made some comparisons between my Legend and one of my friends that has stock ROM. He is having full signal and excellent browsing experience while I have random disconnects or drops in signal level. My thought is that the difference between drivers made by HTC and the ones in CM ROM is the cause. As it is with some other HTC proprietary developments (like Flash implementation or FM radio), could be that HTC spent some more development time in eliminating bugs and making a better driver.
Of course, this will not stop me use CM ROMS, it is a little bit frustrating, but the other things in CM ROM's makes the difference for me.

I think you're right. Yesterday, I tried my friend's phone (which has a stock ROM), using the same AP and there was no dropped signal or disconnected in wifi. I also tried using other android phone brand (5 series from samsung) which also has a stock ROM and there was no problem at all. Drivers is the culprit
Work
Thanks u very much.worked on my milestone
Thanks. Actually worked.

Hello Rapier,
I have installed the CyanogenMod 6.1.1 (stable) on my HTC Desire (GSM / France) with latest radio image (32.49.00.32U_5.11.05.27) and taken some time to configure it. Now, everything seems to run well ... excepted the WiFi (and perhaps also the GSM). My problem is exactlw what you have described:
- on stock ROMs, the WiFi signal is stable and quite strong
- on Cyanogen ROM 6.1.1, the WiFi signal fluctuates, the connection is unstable and gets lost.
I like CyanogenMod ROMs very much. The WiFi issue is the only thing that I was not able to correct. You were speaking about WiFi drivers: would it be possible to extract the WiFi drivers from the latest HTC Desire stock ROM and copy them into the CyanogenMod installation?
My impression is that the CyanogenROM is scanning for networks in the background, even if a stable and strong WiFi network has been found and is currently connected. Perhaps there is a possibility to disable this scanning?
To finish, I have also the impression (I know, this is not very scientific ... but perhaps it could help to determinate where the issue comes from) that the GSM network is also fluctuating. I use WiFi Analyzer (available on the Android market) and when I plot a graph, without moving the phone or even without moving myself, the plot oscillates between -80dBm and -30dBm (I swear that there is nobody playing with the on/off button of my ZyXEL router ).
@sz1a: Thank you very much for your post: this helped me to discover these "hidden" settings, but my configuration is manual on the ZyXEL and everything was fine. Perhaps you should switch the thread to "unsolved".
I'n not a developer, only an ethusiast with a Legend. Also I'm not a Linux expert so I can only guess and experiment...threfore I cannot tell if porting HTC proprietary drivers is possible. I'd say not...if it was, we would have it by now. The main reason I think, is that those drivers are not open source, so nobody can port them since the sources are not available. I'm sure that if it was possible, they'll have been included in CM

pleaaaase help, im running CM 6.1 RC 1
wifi was working fine untill yesterday, i tried to connect to my friends router but couldnt.. i tried putting it in manually too.. then i couldnt connect to any router infact my phone wont even pick up any even my home one.. i tried switching to 14 channs like this said but no luck
any help please
I recently encountered a weird bug when SGSII would establish wireless "g" connection at 54mbps (instead of regular "n" at 65mbps) when doing 3G to wifi tether on my Lenovo Laptop.
My other 2 laptops work fine as expected, however after doing some troubleshooting, its concluded that the wifi router IP forms a "black hole" hope because of which the external communication to Internet dies after 4 or 5 hops (internal to the ISP). While doing a Trace route, the first hop (the IP of the phone's wireless router - 192.168.43.1) doesn't respond to the trace route ICMP requests and fails, however it does work for the next 4 hops before eventually dying after that.
This proves that wifi connectivity between the phone and laptop remains good despite it being downgraded as "g" network when my laptop is capable of "n" at upto 300mbps.
Never had this issue before KG5 or higher builds and it seems all the custom kernels and ROMs based on these newer kernels are affected.
As this issue is affecting only my Lenovo Laptop, not sure if it was ever reported.
Fortunately I am able to flash kernels based on earlier than KG5 build like Ninphetamine-2.0.x (till 2.0.5).
All Ninphetamine-2.1.x builds and kernels like "RAGEmod v1-T30" are also affected.
I am currently on "TOUCH X-treme KH3 2.0 'PERFORMANCE'" ROM and fortunately it seems to be working fine on Ninphetamine-2.0.5 as per my preliminary testing.
I have 2 more laptops which seems to be working fine otherwise on any latest kernels.
I would appreciate if someone could shed some light on the reason behind this bug as I am still investigating the cause and on a fix other than older kernel versions.
My primary usage of this phone is completely impacted by this bug and I hope Samsung would be able to resolve this bug before their next official release of 2.3.4 or higher version builds.
Hmm like the battery drain while charging bug on SGS1 I seems to be the only person shaken up by this bug which makes my SGS2 completely useless when using the latest kernels/ROMs.
My laptop has Intel WiFi Link 5100 AGN. Can someone having same/similar Wifi adapter report their experience?
Not surprised that Wifi tether is not used by most of us and hence such bugs go unnoticed and I paid a HUGE price of crashing my laptop which trying to fix the issue as I never thought it is the phone doing something weird which is preventing my laptop to get proper wifi connectivity.
Unfortunately no resolution till date. All the latest kernels and ROMs are affected. Not sure what is the issue as it defies logic why only one series of Wifi adapters are affected by this bug.
No resolution till date. All the recent kernels are still affected except the one on CM7 ROM.
Seems I need to wait for this update to become official in India before raising with Samsung here.
Ahhh.. Finally a respite after several MONTHS! The latest Siyah v2.5 kernel (http://forum.xda-developers.com/showthread.php?t=1263838) with new Wifi Driver has restored Internet access through Wireless Tether though the speed is still limited to g instead of regular n at 65mbps. But atleast I can now switch from the good old Ninphetamine-2.0.5 kernel to this latest kernel I always wanted to keep. Such a RELIEF!

I have faced the similar problem. But how my problem was solved is give below:
Update you windows OS using windows update
Then manually switch off the radios and switch on
That's all and now I can use wifi tethering as normal. First check with second option, if doesn't work, then try updating the PC OS too.

Latest Siyah 2.6.x kernels have AGAIN brought back the bug on my face!
None of the other options you suggested worked. I have spent hours trying to figure it out and this is what I get when I am affected:
Tracing route to 8.8.8.8 over a maximum of 30 hops
1 * * * Request timed out.
2 164 ms 123 ms 127 ms 218.248.84.5
3 228 ms 68 ms 81 ms 10.42.43.101
4 79 ms 79 ms 80 ms 10.42.43.28
5 * * * Request timed out.
Doesn't make ANY sense on how the first hop is getting blackholed when it otherwise respond to ping requests. I am able to reach till the last hop of ISP before dropping off.
Can any network gurus out here explain this phenomenon? I am unable to locate any logic behind it.
Hope Siyah team fixes it soon for me to enjoy a glimpse of Voodoo Sound on my SGS2.
I have a Lenovo T520 and am using the KK2 stock firmware/rom with no problem whatsoever in tethering...using it at this very moment
It actually seems to be affecting only Intel 5100 adapters like on my R400. I have 3 other laptops and a mobile phone which are working fine otherwise
As I said, it defies logic why only this adapter has compatibility issue when even older Intel 39xx based adapters work perfectly fine otherwise.
Fixed in Siyah 2.6.2 kernel again
Finally got it fixed on Siyah 2.6.2 kernel (to be released shortly) while working directly with the dev "gokhanmoral" in the past few days. All seems to be working now like it was in 2.5.x builds for me.
I sincerely thank gokhanmoral for taking the pain of looking at this isolated bug by Samsung which has fortunately been resolved on the latest drivers (to an extend, still no n mode access).
My i9505 has been misbehaving when trying to connect to 5GHz wifi since the 12th of October, when I flashed the then-newest official Cyanogenmod 10.2 nightly; before that it had been working with any problem on those same nightlies. Something must have been introduced between then and the 2nd of October; I didn't do any flashing during that time as I was abroad on business, so I'm not sure exactly when the change might have been introduced. Since that time I've moved to a 4.4 ROM but the problem persists.
It seems that I'm not the only one having problems with 5GHz wifi on AOSP ROMs - Google turns up various problems on different ROMs and devices. There are even suggested solutions such as editing text files in /system/etc/wifi or changing one's router's channel. None of these work for me.
The symptoms vary. Some of the time the device will simply refuse to connect to 5GHz networks. Other times it will connect and work normally for a time, anything from approx. 1 minute to 30 minutes or more (the latter making me think for a while that the problem is fixed). But, eventually, apps will stop getting a network connection and I'll be unable to ping anything. Despite this total lack of connectivity the wifi indicator will show that the device is still connected to Google's servers. Turning wifi off and on will start the cycle again, until I give up and switch back to 2.4 GHz.
This is rather frustrating and I wonder if anyone has any clue what it might be, or how it might be investigated further.
Has anyone else experienced this problem?

Yes, i have similar problem. i changed few custom roms, and nothing helps. First, it works normal, for few minutes, then wi fi go automaticly off, and then i cannot connect to wi fi network
I noticed this on 4.3 all versions, but since I updated to 4.4 official on my i9505G, the problem went away. I think it may be s bug in the NON-HLOS in the 4.3 roms .. official or otherwise.

I think it came in on 4.3, and I wonder why it is still affecting me on 4.4 as some people are reporting that has been fixed.
When official jfltexx CM11 nightlies come out I'll try a clean flash to see if there's any change.
I decided to try something similar - I updated to the latest UK firmware and then did a clean flash of an unofficial CM11 4.4.1. 5GHz Wi-Fi still doesn't work properly, as above.
I can get better results within a couple of metres of the AP.
Usually i switch on WiFi and disable mobile data manually while at home. It turns out that i don't receive any Push Notifications like WhatsApp, Threema, Facebook and GMail/Inbox (those who are using gcm) when the device is connected to WiFi solely and the screen is locked. If i unlock the device after a certain amount of time, a bunch of notifications are popping up. This is reproducable and won't occur on mobile data. Just do the following, while i.e. at home:
Connect to WiFi
Deactivate your Mobile Data
Lock your screen and let your Device rest for a couple of seconds
Tell someone to send you a Mail to your Gmail Account (or on any other GCM-Push related way)
You probably may notice that your device won't wake up to notify you about this incoming message until you pick it up and unlock it. I have tested this since weeks with multiple official nightlies of CM12, custom builds and even unofficial CM12.1 builds, they all show the same behaviour. Even with official CM11s this issue persists, but can be worked around by unchecking "WiFi Optimizations" in advanced WiFi-Settings. Unfortunately Lollipop doesn't have this WiFi Optimization trigger anymore. Ofc "Keep WiFi on during sleep" is set to "always". After all tests i came to the conclusion that the device simply gets no wakelock trigger from notifications if connected to WiFi solely. I've fixed this for me by fiddeling with the configuration files (root needed).
Open /system/etc/wifi/WCNSS_qcom_cfg.ini and change
Code:
hostNSOffload=0
to
Code:
hostNSOffload=1
After this change and a reboot, your device should be able to wake up from incoming notifications instantly while on WiFi. Some custom ROM, like SlimSaber have set this out of the box, while official cm nightlies and other custom ROM, like exodus, haven't.
Have you tested IPv6 over WiFi with 12.1? As that is also broken on 12.

Usually i've disabled ivp6, because of the known problems with it. I've tested it with ipv6 enabled and it worked.
Meanwhile i was able to test a lil bit more on other networks. It seems like this all is router dependant. While having the chance to exessively using another WiFi network yesterday, i was able to check that there are no such problems as described before. After went home, problems reappeared. I have to conclude that there must be some culprit with my router at least (Telekom Speedport W724V).
I noticed such notification flood several times.
I can't say under which circumstances because I didn't care about it yet but your post made me remember this.
I gonna investigate that asap.
As far as I can say this happened only at home yet. My router is an AVM FritzBox 7390.
On my OPO I have usually always one of the newest official CM12 nightlies installed.
I've tested stock settings while connected to a completely different router a few days ago and wasn't able to reproduce the issue. It really turns out that it has something to do with certain routers, in my case a Speedport W724V Type A (by Huawei). It seems like this issues has something to do with ARP Offloading and filtering of Broadcast/Multicast. As far as i understand, Androids MAC Adress isn't hard coded and the router loses the connection to the device if it goes into sleep state. Therefore the router has to broadcast via arp to look for the device, but the device simply doesn't respond to the arp request, coz the wifi driver is configured to ignore that broadcasts and continue sleeping. This issue is, as i read, present since KitKat where it could at least be worked around by disabling the WiFi Optimizations, which seems to be only a checkbox for above mentioned manual method Lollipop.
Currently i've no idea how to fix this in a better way, since my described method works flawlessly, but it's definately a lil battery drainer. Another way to work around this is by setting "Keep Wi-Fi on during sleep" to "never" and let the device handover the data connection to mobile data while sleeping. This, at least, ensures the battery savings which were intended by the developers.
Steve Kondik merged an interesting commit today, which i am not aware of if this will change anything related to this issue. As this commit was merged into cm12.1 branch i doubt that we will see anything related in cm12 based roms, nor the upcoming cm12s. Maybe some nifty dev like @ak or @Lord Boeffla can take a look into this and implement it into their kernel.
I put the interesting commit into my cm12.1 kernel, which comes out tomorrow.
If all goes well I can look to back port it to cm12 and maybe even cm11(s).
Let's see. First we need opinions on the test kernel tomorrow.

Currently i've no idea how to fix this in a better way, since my described method works flawlessly, but it's definately a lil battery drainer. Another way to work around this is by setting "Keep Wi-Fi on during sleep" to "never" and let the device handover the data connection to mobile data while sleeping. This, at least, ensures the battery savings which were intended by the developers.
Steve Kondik merged an interesting commit today, which i am not aware of if this will change anything related to this issue. As this commit was merged into cm12.1 branch i doubt that we will see anything related in cm12 based roms, nor the upcoming cm12s. Maybe some nifty dev like @ak or @Lord Boeffla can take a look into this and implement it into their kernel.

It fixed my wifi bug so far on euphoria 5.1
Okay guys, i've tried AK's latest experimental kernel (v203). Beside of some small problems which are still under developement, WiFi seems to be fixed completely with the implementation of the new prima drivers for me. This could mean, that they will be automatically fixed with the release of the official cm12.1 nightlies. As for now i will thank everyone, especially @ak and @Lord Boeffla for participating and help to hunt down and solve this annoying issue. You're great guys :good:

Thanks. With the latest beta kernel for cm12.1 which I released this morning, these drivers are also included.
If they turn out to work better - my other kernel variants (cm11s, cm11, cm12) are also already ready with these new drivers backported. Just have not released them as I want to give it some more testing.

Anyone else notice the same issue on Oxygen Os? I'm not sure if it's just the router I connect to at work, since this doesn't happen at home. Can't tell yet, will give this a shot.

Would be an interesting test.
We cannot look into the driver used for Oxygen OS as the kernel code is not yet released as far as I know (if it is, I would be happily be corrected )
Andi
I'll bet that oxygen suffers of the same problems as every cm12 build does (even if it's more aosp) and CyanogenOS 12 (CM12s) will also.

Let's see.
I backported the new drivers to CM12, CM11s and CM11 already.
Just need to decide whether I ship that or not

Just to report back, this did seem to fix my wifi issues, although I've since switched to Exodus, so I didn't have a ton of time to play with it.
Thanks for taking the time to investigate this issue. I should have done the same I will ago when it started bothering me.
I will try one of the kernels and see if it fixes it. If not I'll try your method once I am back home.
Thanks!

You're welcome. I have to admit that the problem reappeared. So the new Wi-Fi drivers have no permanent solution for me. As told in the other thread I found my temporary solution by simply let Wi-Fi auto turn off when device for to sleep. My data plan allows me this easily, but if you're on a 200mb data plan this could be ****ty for you. Let's see if future commits of cm will change anything.
I fortunately have a 3gb lte contract, so this shouldn't be the issue. I just don't want to accept that there might not be a solution without tradeoffs.
I'll let you know if I find anything

Would be nice. I'm hunting this issue down since January, so far, as said, without any real solution other than using another router. it works anywhere except at home, so i know exactly how annoying this is. It's not that big problem to use mobile data when screen is off, but is pisses me off, if i just forget this sometimes and miss urgend messages from WhatsApp or Threema, coz they're arriving hours later. As desribed above, there is a way to prevent the OnePlus to not filter the WiFi Broadcasts. You just have to edit this one line in the configuration manually, but it comes at the cost of battery.
Hi Guys,
I just got my Prime Day Essential set up and after updating to the latest Android 8.1.0 build with the July patches I'm one of the lucky ones with the 5ghz Wi-Fi issue, where when I connect to a 5ghz Wi-Fi, the connection and speed starts throttling down to no bandwidth at all. My workaround has been using the slower 2.4ghz SSID. I also have the issue where the Play Store download sometimes waits forever to download in the queue.
What do you guys do with this issue? Flash to Android P? Something else with you router?
I really don't think it's my router because obviously all other devices in the house are working flawlessly... Appreciate ANY help... Thank you!

Welcome to the "club"... :silly:
I've been searching for a solution to this issue since I got the PH-1 about 3 weeks ago. Here I read your post, and I just did a test to disappoint myself once again with the issue... but... it doesn't seem to be happening anymore?!??
I am running AOSiP (8.1 w/ July security patch) with the latest Neutrino Fornax kernel (important because it has the latest Android P WLAN drivers, same as the Essential P B3 066 stock release). I am going to see if I can determine what might have fixed it, but I've been running this setup for a week and it originally had the problem.
What I would suggest:
- Don't spend much time diagnosing your router, all the changes suggested in these forums didn't change anything for me at least (YMMV). As you said, all other devices in your home are working fine (same here).
- Don't install P to resolve this issue. I clean flashed the Essential P Beta Release, and the problem was still there. In fact it seems to have been worse, with PS download stopping completely with a message "Waiting for WiFi".
- Try a different kernel. Try the latest ElementalX kernel (3.0.6). I believe it has the updated WLAN drivers as well since it supports Android P. I don't believe the Neutrino kernel works on stock.
- Check your PlayStore version, I think mine was updated recently (11.0.50-all[0] [PR] 206665793)
I am going to look into this more, and if I find a definitive "this is what fixed it" I will post it here. Good luck...
This is issue is not present for me on 9.0 further the speed difference between 2.4 and 5 isn't really world eg being on 2.4 is still faster than most broadband connections. This is seems to be a google security patch issue on 8.1 and likely will be fixed in the next patch. When the latest 9.0 beta came out it seemed to go away. So it seems they know how to fix it.
I have no problem either, latest android P, rooted with rey darkroom kernel
Edit, can u guys connect to any wifi? There seems to be an issue, after flashing various ota's, stock images, or treble gsi's that disable wifi and Bluetooth and the only way i have found to fix them, isfor android P at least) to flash a july 8.1 images (flashall. Bat) then flash android P to fix wifi and Bluetooth issues.

Thanks for the warm welcome, my friend and even more so, thank you so much for your very detailed post and what you've done to remedy.
I assume messing with the kernel and etc will require Bootloader unlocking and rooting, right? I haven't rooted a phone since the V20, just been opting out of that life for secure payment methods, stable battery and just general ease of moving from phone to phone like I do ?.
What I did last night... Could be a fluke, could be placebo, however, changing the channels on my 5ghz network, rebooting the router, I've been connected to the 5ghz network with my Essential for about 12 hours now with no throttling. I'm not sure if it was in fact the channel change or rebooting the router that cleared things up? Albeit, the signal strength on this network on this phone is the lowest I have seen between the Note 8, HTC U12+, iPhone 7 Plus...
Please keep the research up, I will too, this problem really has no documented solution yet.

Thank you bud, good to hear you're not seeing the issue... But honestly, it does exist for some of us. I really hope it's the issue with the July patch, that'll make things so much easier! Although, I disagree 5ghz is much faster for me than my 2.4ghz network...

Thanks for reporting, good Sir. Yes, I can connect to any network, just low signal strength and the choking issue I had before my router change. Bluetooth seems stable with my smart watch, though the watch seems to be draining the battery faster on this phone... Who knows man ??
You might have noticed I am on the P beta. Also have you run actual wifi speed tests or are we taking seat of the pants feelings?

Hey bud, yes good to see promising reports from P beta... Hoping the bad WiFi is resolved for the ones who get it.
And yes, speed tested, repeatedly. Sadly, Essential's top speeds are way worse than the Note 8, HTC U12+, iPhone 7 Plus... I'm talking almost 100mbps less ?...
For whatever reason though, the choking of the bandwidth down to unusual issue has gone away. Not sure if rebooting the Router did that? WiFi signal is also the worst I have seen on this phone out of all the others mentioned...
I appreciate you sharing your experience.

So your downloads are not as fast as your other devices but you no longer see the downloads slow to a crawl (~100KB/s)? My downloads are not slowing to a crawl either any longer. Something must have been updated from a Google perspective because nothing I changed could explain the issue just going away... :fingers-crossed...

Haha well my good luck didn't last too long, I fried my data, playing with Substratum, on a rooted system :'(... but here's to hoping the 5ghz good luck continues! Don't you love it when "magic" is the answer !?
All jokes aside, my WiFi signal and radio is still the weakest hardware I have EVER seen on ANY device!

I just had a issue with Substratum as well... what do you mean "fried my data"? I was able to recover my system using the Substratum rescue, copied to the cache/ partition and flash in TWRP. Did you already re-flash everything?

Hey bud, yeah, I was playing with Substratum on a NON-rooted, bootloader locked device with Andromeda. So when I had the bootloop, I had no custom recovery in place to flash the rescue zip. :'(
So I "fried" my data, beyond retrievable, I mean. I was surprised that the Essential stock recovery didn't even have a way to install update.zip? That way us non-rooted folks can always save our rescue zips on our computers and see if there was a way to sideload the zip through the stock recovery... Oh well, either there is a way, or I didn't know and couldn't get enough help in time in the middle of the night. I needed my phone working in the AM...
I have had 7.01 when I got the phone yesterday. Went to 9 same day and I can't watch a video. Speed test shows 1.2 M down 2.3 up. I checked other devices and they are showing 70 down and 10 up
My Essential didn't even see my 5Ghz network on 8.1, but I just updated to 9, and now everything is good. Getting 72mbit on a 75mbit connection, too.
On 9.0 rooted with ex kernel on 5ghz ac 866mbit no issues at all... I get 40 megabytes a sec on my wifi.. I have 65 megabytes a sec with my current isp. I why straight to 9.0 phone was on 7.1.2 when I got it a few days ago.

I just did the see 5th security patch update while already on P. My ph1 has never been able to connect to my Xfinity 5ghz channel. Actually, it will sometimes connect, but says 'connected (no internet)' then drips connection. So it's ALWys had trouble with that. My HTC 10 does not, my V30 does not, my M7 does not.
Since the 9/5 update, even my 2.4ghz channel is crazy slow. I get about 3mbps down with my case on. Took off case and get 15mbps. Verified thru multiple tests. My V30 gets 63mbps on same 2.4 channel.
Anyone have this situation? I can't seem to find any further settings in wifi settings to try to see if a setting is wrong.
Does the ph1 just have the worst wifi radio ever? Or is there somewhere in setting that I can change something that I just haven't found? Much thanks.
Stock. Not rooted, no custom kernel,etc. I've been hesitant to root this device because of the A/B slots confusing me a little and just don't have the time currently to really dig into it.
I've the same problem with 5GHz wifi... Connection is very poor. Automatically reconnect to 2,4GHz network. My iPhone 6s didn't problem with this. I don't know, how fix it.
Xfinity routers suck. That said my PH1 connects just fine to my Linksys 5ghz AC channel. Works all over my house and only switched to the 2.4 GHz when I go outside.

What are you guys using to confirm throughput? I'll be testing my replacement (recording audio issue with the one I purchased) when it gets in.
I do file transfers from my PC to my phone and back again and measure the time vs size of file. Over the local network obviously.

I've Tp-Link Archer C1200 with 5GHz and wifi AC. Other devices like a MacBook Air, iPhone 6s and ZTE Axon 7 works perfect with this router on 5GHz and AC speed. I think, that problem is with my Essential Phone.
