Hello,
I have a Moto X pure purchased a little less than a year ago, and I noticed an issue with 5GHz WiFi speed.
In particular whenever connected to any 5GHz AP the connection is established but almost no traffic goes through (speed test shows it crawling, especially in upload, and it is completely unusable)
Connectivity over 2.4GHz WiFi and LTE works perfectly, so it does not appear to be an issue due to radio/modems
The phone was unlocked to gain root access, has been used on Official Motorola ROMs almost all of the times, with one single LineageOS test to confirm if the issue is related to Mororola radio/modem or if it appears to be hardware in nature.
Given the fact that the same exact result is present with LineageOS, I contacted Motorola support, in order to request a repair.
I am aware that by unlocking the phone I voided the warranty (even though I have heard of several users in this forum that were able to have the phone repaired/replaced free of charge after the unlock), but in my specific case the support rep stated explicitlkly that Motorola would not service the phone at all:
"Dyril: Yes. Once you unlock the boot loader of your device, we can no longer process a repair for it. You may refer to this link h t t p s://motorola-global-portal.custhelp.com/app/standalone/bootloader/unlock-your-device-a for the disclaimer before unlocking the bootloader. " (URL edited to allow the post.. . but is the default disclaimer before unlock)
The disclaimer in particular mentions the warranty being voided, but that page does not include any statement indicating the fact that Motorola would refuse to service the phone even at a cost (I asked in the chat if there would be a cost for the repair given the voided warranty)
Does anyone have any direct experience or contact that could help me on this matter?
Should I proceed with a repair request directly, ignoring the support chat?
Thanks

I Donno worst case they reject it the unlocked bootloader was supposed to void warranty with the exception of hardware if there is a defect in the hardware.... But I would try loading a full factory OTA image one that would have any modem updates...

the issue was present with every ROM I tried, I tested all official full factory ROMs from Android 5.x to 6.0 and also LineageOS too, but issue was present all of the times, suggesting that it would be an actual HW issue, so hopefully still covered
Unlocked bootloader voids warranty, period, regardless of issue or cause (except EU)... I still have a tough time believing this is a hardware issue though, 5Ghz is finicky, and it uses the same antenna as 2.4Ghz in this device as far as I know.

I understand the warranty is voided, but as mentioned in the initial post I also asked if the phone could be repaired at a cost, and their complete refusal would be the issue and also surprising.
As far as the issue being software caused (drivers/radio, rom) could you suggest any additional kind of test I could perform?
I reflashed the phone multiple times using fastboot/mfastboot using all of the moto x pure roms I could find on xda-dev and dload from motorola support site, and also tried the latest LineageOS nightly (that might possibly be using different drivers/radios)
I agree that the fact that the 2.4 is working properly would suggest that the antenna is functional, but from what I gathered from h t t p s://forum.xda-developers.com/moto-x-style/help/moto-x-xt1575-wheres-antenna-t3338080 there are actually different antennas for the different bands (thing that would make sense due to the physical size requirements to optimize reception on the different frequencies) so that might explain why one band works and the other does not
In my experience, 5GHz is sometimes problematic on all of my devices. Unfortunately this seems to be a very common issue. The 5GHz band is well known to have issues with range when it has to go through walls, even a single wall.
Is your router right next to a television or other electronic device? If they are working on 5GHz (not necessarily connected to your router), then they could be interfering. Not saying this is the issue, but just an idea to look into.
The issue presents itself even close to the router, and testing with a Galaxy S4 or a Nexus 7 2013 from the same exact position allows me to reach speeds of 100+Mbps, while the Moto X Pure crawls, and the same behavior is experienced with different routers/APs even of enterprise level.
Do you have any suggestion on possible tests or ROMs/modem radios to flash to confirm it is not a software issue in any way?
Sounds like a H/W issue to me. I have had zero issues connecting to 5Ghz WiFi at my house.
Hey @kattolo
I have some issues when connecting with my phone to a D-Link DIR-822 on 5Ghz, but no problem at all with my TP-Link Archer C9.
I'm not sure exactly why, but i tested on the same place, just placed the D-Link one, try it, bunch of problems in 5Ghz (none in 2.4Ghz network), took it off, replaced with the C9, it always gave me much better speed, connection reliability and range.
Try with other equipment (routers) that can provide you 5Ghz networks, just to be sure it's your phone and not the emitter.
Obs: sorry for any english mistake, not my main language

Mine is a XT1581, the Chinese versio of Moto X Force. No matter it's stock ROM 5.1 or 6.0.1 EU, the problem only occurs on 5Ghz wifi. I've tested it with my home router, a old Netgear 802.11n device with 5Ghz band maxing 300mbps, and also tested it in my office with multiple AC routers supporting up to 866mbps.
My phone connects smoothly with those 5Ghz wifi, showing the wifi logo on the notification area on top of screen. But once I run speedtest app or browing the web, almost within seconds, the wifi traffic drops to zero, then even the wifi logo is still on, in Setting--WLAN, the phone starts searching for wifi signals but eventually to no avail. So I'll have to manually turn off wifi switch and then on again to connect to the 5Ghz wifi, and the loop goes on.
An interesting point I've found is that, when the 5Ghz link speed between my phone and the router is somewhat lower, it works fine, with almost no wifi disconnecting or drops. For example, my home router supports max speed 300mbps on 5Ghz, and if I manually set the router's link mode to 130mbps, my phone works good. In my office, I occasionally discovered that if the link speed is like 173mpbs when the phone is connecting to a certain AC router, no problem at all with 5Ghz wifi.
I guess I've tried messing with every possible parameters in /system/ect/wifi/WCNSS_Qcom_cfg.ini, but no luck at all.
As I said earlier, no problem for me with the Archer C9 (I'm 8 ~ 10 meters away from the router in straight line, 2 rooms far from where it was placed)

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
Hello. First, great forum- I can feel the love, as well as the collective genius at work here. It's refreshing to find a forum where people actually know their sh*t on a real, technologically advanced level. It's relieving as well, considering the headache that my new G2 is causing... as follows:
This is a Sprint device and I am still within the time frame to return if a resolution is not found.
Issue:
1.) While wi-fi remains connected (doesn't drop), it is terribly slow, averaging .8 - 3 mbps. Whereas, other Samsung android devices are averaging 15-20 mbps. Internet is cable, and I have reset the modem without experiencing any performance increase. (technicolor TC8305C, bgn)
2.) 4g is no better, averaging a mind boggling .5 mbps. (Don't even get me started on 3g- .1-.3 mbps)
3.) If 4g is even able to connect, which is rare... it disappears and and is nowhere to be found, or be (re) enabled.
Attempted (unsuccessful resolutions):
1.) Performed Sprint recommended troubleshooting techniques:
a.) updated profile
b.) soft reset(s)
c.) hard resets- multiple
2.) contacted customer care: received "refreshers," and was walked through numerous settings and performed various resets.
Recommended CC resolution: return device for exchange.
3.) Sprint store attempted to identify problem, and in the process found that their demo, along with employee handsets (G2) as well as new unboxed versions had the same problem. They offered to switch to an S4 or Nexus5 for free, or wait a couple days to see if the LG rep could offer a fix.
(further) Resolution: pending
Here's the deal- I think we can all agree that this phone is kick ass. Therefore, I would rather not switch, as I enjoy the experience it provides, as well as the satisfaction of getting to really bond with a device when troubleshooting them. Though, this phone seems to be pretty 'buggy,' and while I don't mind tinkering with computing devices (been seeing the blue screen since win '95), I'm not sure I want to be dealing with the potential hassle with a device we all rely on day in and day out to be our life blood... plus, just because I don't see/haven't experienced the other issues others have, doesn't mean they won't potentially manifest down the road. :/ Maybe the Nexus 5 is the better choice... but it seems like cost cutting has taken place in a couple areas- battery (2300), and the camera. Almost like the G2 is the flagship and the other is mildly scaled down in certain aspects even though the end result is compelling for both.
Please know that I am scouring middle earth low and wide for resolutions, and have not composed this post without first looking and becoming familiar with other peoples similiar experiences. I will continue to fact find, and I apologize for not reading all related threads before posting, but time is of the nigh, as I am still within a time frame to return in case the problem is inherent to this specific device (a lemon). Plus, I don't quite understand everything you're talking about, as I've never had/chosen to dig that deep into the obscure settings and techniques I've seen listed (and also because I JUST got it) Hence, the user name- g2 n00b.
So thank you in advance for your time in helping with this. It is both greatly appreciated, and not without gratitude on my part. Also, I hope I displayed proper educate by formating this post in a manner which is easy to sort through. K. let the trouble shooting begin.
also, to the mods- sorry if this is thread/issue has already been covered elsewhere. I also posted this issue on another board and nobody had heard of this problem, so I am fairly confident that i may be justified in having poted this. However, feel free to delete/lock/merge/ if I just didn't see it.. but please provide the link so I can further fact find, because I'm stumped. Thanks.
I just did a speedtest on mine (Also on Sprint) using Wifi.
Same speeds I get on my PC.
It's an oddball suggestion but did you disable the Sprint connection optimizer?
Optimizer enabled. Though, I have tried disabling it and running diagnostics to no effect- doesn't matter what I do, it still won't exceed 3mbps, unless I am lucky enough to receive 4g in certain areas.. then it's a 'blazing' 3.5mbps, but usually .8. I have msl code and have adjusted band priorities and still no difference there, including ##72786 to reset default connections to make sure nothing was adversely affected after investigating the issue.
I'm really bummed. I love this phone. I feel like everything I felt I was missing in the S3/S4 are present here. Love the interface, form factor and all of the settings. Maybe I should take Sprint up on there offer to get an S4 a Nexus 5, but I REALLY don't want to go back to caveman battery hog status on the S4 and have to purchase a backup. I imagine the N5 is more efficient in this area, but it still has a 2300 battery vs 3000 in the G2. Needless to say, I'm frustrated and confused.. but often times, such is life.
Any thoughts on the N5, or suggestions to further trouble shoot are greatly appreciated and welcome?
I have disable the connection optimizer and have done this http://forum.xda-developers.com/showpost.php?p=47423537&postcount=1
The only other idea I have is hit up a coffee shop and due a speed test on their wifi.
The sprint stores by me have crappy wifi speed hence the coffee shop.
I seem to have mostly resolved the issue. I switched channels and encryption protocol. Apparently, my g2 didn't appreciate AES very much. Has anyone else seen performance differences with their device when comparing AES to TKIP? If so, are they drastic? I would think AES would be fine with the g2, considering how advanced it is. I consider it to be somewhat unfortunate if I am forced to select TKIP just so I can get a decent connection. That is, unless of course there are settings I can alter in the ##data# screen that can make better use of this encryption. Is there anything I can do now that I have narrowed down the culprit?

What wireless router are you using? I use a D-Link at home and my G2 kept connecting and disconnecting repeatedly. I was able to fix the problem by updating the router's firmware to the latest version. We've never had any problems with other wifi devices on our router, so it seems the G2 has some unique peculiarities WRT wifi.
I'm running AES with no issues, but noticed following.
LG (Sprint) connects first with a slow 72mbps and switches after a while to a faster speed of 433mbps
I have an Asus Router RT-AC66R, if I play around on the router with Frequencies or the wireless mode, LG would go down to a slow speed.
Don't have Optimizer enabled.
I suspect your problem is a router problem and not the phone.
At work I've got a wifi network consisting of 9 Aruba IAP105 access points in virtual controller mode.
Sitting at my desk, with a Verizon Samsung Galaxy S5 on 4.4.2 I've seen it roam between the nearest two access points 5 times in two minutes. This issue isn't affecting a Galaxy S3 on 4.3.
The two closest access points have significantly different signal strength - the phone should connect to the stronger one and hold that connection, but instead it's constantly switching which makes the wifi connection practically unusable.
I've worked with support on the access points and they've basically decided it's a device issue since the logs show the phone removing it's own association from each AP. That combined with the fact that the issue isn't earlier versions of Android, iPhones, or computers leads me to believe they're correct.
There's also a Motorola Droid Maxx that's definitely affected, as well as a handful of other Android devices I can see in the management console for the wifi network but haven't personally inspected.
I've seen lots of threads of similar issues, with the most common fix suggesting to change the channel of the access point which isn't applicable here since these access points automatically select the best channel available and negotiate with each other to avoid overlaps.
Any ideas I could try or suggestions? Thanks!
Anyone having issues connecting to wi-fi networks on channels 12/13? On my device I'm unable to see SSIDs in these channels most of the time. Sometimes I can see networks in channel 13.
Am engaging with Google tech support, so will keep you posted.
What country are you in?
UK
I seem to be the only person on my street that knows channel 13 exists. No issues for me connecting. Although I run my phone to my 5Ghz connection normally, I can connect to my 2.4Ghz if needs be.

Good good.
I'm wondering whether it's down to me not activating the SIM in the phone as yet? Like a double check that the phone should be allowed to use 12&13 (rather than just selecting English UK as the language).

There's really no difference in using that over channel 11 in your case with the co-channel interference.
YES!
It's not just me then. Home router (2.4Ghz) is on ch.13 and when i return home the device will not auto-connect until i toggle wifi off and back on again. Wifi works fine until i leave again. connects fine to my wifi network at work but that is different channel and on 5Ghz too.
RMA'd my device and the new one was bad. Wouldn't see my network at all, but wouldn't register my Sim card either so I have just returned this replacement device. Replacement number 2 is on the way.
I switched to ch.12 and the same thing happens at home. Didn't try any other channels as they are too noisy. So I wonder if this is a software issue? I'm in the UK and the router is made by technicolor for Plusnet.

If channel 11 is noisy, then so is 12 and 13.

You might want to change to channel 11. With the current setup you are not only killing your own data rates, but also the rates of everyone on channel 11. These channels are not supposed to overlap, because that creates interference. Switch to channel 11.
This is my WiFi situation. I'm normally on CH.13, but switched to 12 as a test.
My 2nd unit arrived last week, and unfortunately it's the same issue as before - no channels 12 or 13, not even visible. I'll be back in touch with Google today.
Hopefully this is a software issue rather than Google/Huawei spec'ing a duff wifi chipset.
Google spoken to and basically it's a case of tough-titty - some devices aren't going to work with channels 12 & 13.
For anyone else reading this, I had this problem and 'solved' it.
If you find that you can't see channels 12 and 13 then it's almost definitely caused by the Wifi country code restrictions.
I got my Nexus 6P here in Korea and initially tried it out with no sim card. Even though the location is set in settings, without a sim card it doesn't get the wifi country code set, and I couldn't see those channels. As soon as I inserted a Korean sim card, I was able to see them.
If you are in the UK or elsewhere, using a local sim card and you can't see those channels then chances are either your country doesn't allow it or the code is already set. Either way, your options are just accept it or try one of the 'not officially supported' ways to getting around it. That's likely why Google said you were out of luck. It's possible but involves rooting etc. I think. Just search for 'change wifi country code android'. Good luck.

I am afraid that the issue is not as simple. I also have problems with channels 12 and 13, however my phone can connect to those channels, but only for a while. I quote the report I filed in the AOSP bug tracker (not yet assigned, though):
Before I continue, I am based in Switzerland, use a Swiss mobile provider (Swisscom), and I bought my phone through Google in Switzerland. This is relevant because in Europe 802.11b/g/n channels 12 & 13 are allowed, while in the North America they are allowed only under "low power conditions" with the effect that, AFAIK, many devices simply do not support them. My Nexus 6P however should (and shall) support those two channels.
Now, the problem.
I have two access points at home, both in the 2.4 GHz band: one on channels 4+6 and the other (normally) on channels 12+13. What I noticed is that my Nexus 6P would initially connect to the strongest signal independently from the channel, as expected, but then after a while (a couple of hours, maybe) would just stop seeing the signal on channels 12 & 13. Not just my own WLAN, but also neighborhood WLANs on the same channels. This means that the phone can be sitting a couple of meters from the AP in my office (channels 12+13) and be connected to the AP at the opposite corner of the building (the one on channels 4+6). I checked with "WiFi Analyzer" and the phone really does not see any signal above channel 11.
Disabling and re-enabling WiFi will make the phone see channels 12 & 13 once again. However after a while the problem appears again.
At home this is just an inconvenience: I moved the frequency of the second AP to a different channel and that "solved" the problem. On the other hand this might be a much more serious problem when I am in an environment where I can't change the WiFi settings. Maybe I want to connect to a public hotspot broadcasting on the "wrong" channels or I am at the office in an area covered by APs on channels 12 & 13. Tough luck.
Incidentally, I saw at least one report of someone who had exactly the same issue: he had to disable WiFi and enable it again to get the phone to connect to his WLAN (on channel 12 or 13, I can't remember). I also have to say that in our household we have a few other Android devices (2 x Nexus 7, 1 x Nexus 9, 2 x Nexus 4, 1 x Moto X Play) running either 6.0.1 or 5.1.1 and a few other devices (iPhone 5S, iPhone 6, laptop, 2 x Kindle) and none exhibits this behavior. It seems to be specific to the 6P.
I suspect that after a while the WiFi driver simply reverts to its default regulatory domain ("US", I assume) and stops listening to channels 12 and 13. Why it might do so is anyone's guess. Maybe doze interferes with the driver.
Same problem here. The only way to reconnect to WiFi channel 12 or 13 is to manually switch WiFi off and on again on the 6p.
I'm in Hungary.
Guys, there is a thread in the Nexus Help Forum and I reported the issue in the AOSP Bug Tracker. Add your contributions to those threads and star them. Let's try to bring this to Google's attention, otherwise we will never get any action on this topic.
Edit: For some reason I can't add links to the post. Please search issue 197106 ("WiFi 2.4 GHz channels 12 & 13 not working properly on Nexus 6P running 6.0.1") in the AOSP Bug Tracker and the post "My Nexus 6P can't connect to Channel 12 or 13 WIFI's" in the Google Product Forums.

I have been trying for a week to extract some information from Google and Huawei, but I must say that their support just doesn't know anything about this issue. It's even difficult to get someone to understand what the problem is: one Google support guy thought I was talkng about LTE channel 12, for example. Huawei support started talking about options in the WiFi settings that are not there, then they wanted to guide me through adding a new WLAN, and finally started clutching at straws, giving more and more fantastic explanations of why it might be so.
Bottom line is: nobody I talked to ever heard about this issue.
I would really like to understand if it could be a hardware issue (which I honestly doubt) because my RMA window is closing soon and I don't honestly know what to do: apart from this WiFi issue my 6P is absolutely flawless and I do not want to risk getting a new telephone only to find out that WiFi still does not work as expected and it's also got other issues. (And, yes, something like this already happened to me.)

Hello, I also have the same problem. As I can report it to Google? I have not found a way.

Did you call the Google Store Support? I hope that if they hear the same reports repeatedly they will take notice.
If your telephone is unlocked (and if you are on XDA chances are it is), flash Franco's kernel. I did it today and now my problems with WiFi are gone. Plus Franco's is known to be very battery efficient. It's a win-win situation.
Title pretty much covers it.....I have had it with the WiFi issues on the OP8 Pro and was going to go back to the OP7 Pro.
....but people are saying that they are all fixed in Android 11 beta on the OnePlus forums...is this true? And what about Dual SIM which I also need on occasion?
If I move to A11 OB2, can I root and get GPay working?
Is it stable enough to be a daily driver?
Many thanks in advance...

You can root OB2 device, and the OB2 seems usable and also stable enough for daily usage.
I recently acquired a oneplus 8 pro purchased directly from oneplus.com. I have model IN2025. It is the 12gig ram 256 gig storage version. I also have a samsung active watch 2 which I again have had no problems with my oneplus 7 pro. When I initially acquired it, I tried using it with the android 10 non beta firmware. I had multitude of issues up to and including:
1. high difficulty (to not at all) connecting to either my 2.4ghz wifi network OR my 5ghz network. It would state connecting however stall at obtaining IP address. No other devices have issues connecting to either networks including my older oneplus 7 pro.
2. if it would finally connect, while it may state that the 5ghz is connected at 300mbps or the 2.4ghz connected at 144mbps, with random speed tests I would not experience anywheres near those speeds (my ISP dishes out 200mbps). at most I would get 30mbps on my downstream....again if it even worked.
3. both the 2.4ghz and 5ghz networks would often disconnect and never reconnect if and when they did successfully reconnect
I installed the open beta 1 and then did OTA to open beta 2. This has helped quite a bit HOWEVER I've experienced the following issues:
1. while I have no longer received the locking up on obtaining ip address, even if it states I'm connected to my wifi (either the 2.4 or 5ghz) the network is still extremely slow
2. sometimes the device while connected to either wifi network will appear to not send any information aka stall which potentially makes using google messages over wifi unreliable as well aka text msgs show up late etc
In both pre and after beta installation 5g has been significantly slower than 4g cellular data(though I can't say much to that as more than likely the 4g in my area has towers closer near by). Also while on 4g or 5g cellular connections I have though not as frequently experienced data stalls.
Things that have helped resolve some of my issues:
1. this I believe is the largest potential bandage: make sure use device mac address NOT RANDOM is selected. After having done that my connecting to the internet appears to be better (even if it still stalls out)
2. while I've not tried it alot as I use bluetooth alot (with the watch I have and my car and wireless headsets)I've read that turning off bluetooth can help both wifi and cellular data issues
I am currently in the process with oneplus of returning the 8 pro for a new 8 pro as I have not owned/had the phone for greater than 15 days. If that does not resolve the issue, I too may go back to a oneplus 7 pro...or perhaps the 'dark side' and go the samsung route.
Just sharing my experience so far!

Excessiveidling,
This is exactly the type of info I was looking for. So it sounds like it is better, but still bizzare WiFi issues that no other phone on the market has. My situation is...
I have to leave bluetooth on because of watch and hearing aids
I need to rely on WiFI calling on occasion and need it to be 100% reliable.
I need working WiFi at home because I use my phone for some applications that connect via my home network, so having WiFi work "most but not all" of the time is a deal breaker.
So at this point I think I am going to switch back.
I've been a loyal OP fan for quite a while (4 phones now), this has been really disappointing. I even bought a new router because someone said WPA3 would help...but it didn't.

While I can not say anything to the validity of the following statement...I have heard in other forums that the samsung devices with the same qualcomm chipset had wifi/cellular issues (especially with 5g).....that was only ONE forum post however unlike the multitudes of forum posts I've seen regarding the oneplus.
If I were to guess, only based upon my limited modding experiences with previous android phones, an updated modem/chipset software COULD resolve these issues...further more a different/modified kernel as well. Doing that would probably void any warranty though and for spending 800+ on a phone, you shouldn't have to modify in order for it to work just as well if not better than an older phone.
I'll let ya know how the exchange goes. I'm willing to give them another shot 1. because of my excellent experience with the 7 pro and 2. because I've seen so many posts, reviews, etc stating the oneplus 8 pro is THE PHONE to have overall.
Thanks,

I read the same thing re - chipset, and agree that is a possibility. The other is a horrible RF design for the BT / WiFi antenna because they crammed in the wireless charging.
But I don't see any of this getting fixed anytime soon. I wonder if the OP8 (non pro) has similar issues -- I didn't check.
Let me know how your new phone works out - an RF HW update or a new batch of chips could change things.
