Wi-Fi problems?

Have any of you guys had any problems with Wi-Fi on the Galaxy Tab?
I've been trying to connect this device with a wide range of routers and keep ending up with no or a very poor signal.
Just upgraded to firmware P1000XWJJ3 and the problem persists.

no, i don't have such problem on JID firmware
BTW how did you update it to JJ3?

Mine JJ2 also is not so good with receiving signal where my laptop or phone easily do.

How far away from the router? Any walls between?
My Tab works pretty well if i'm close to the router, but with some distance between - oh say 5-6 meters - it rapidly decreases and soon enough drop the connection all together. Very strange, been trying different routers and different settings and it's the same all over the board.
Regarding the firmware (JJ3), just go to http://www.samfirmware.com/ click "Tablets" and select firmware and then install with Odin. Easy as one, two, three.

MIne works fine with through thick walls on the balcony. What wireless security/ preamble type have you got? Is the router set to 20/40? Is it transmitting at 100% or auto?

The router doesn't matter. If i sit on my balcony smoking a cigarette, I either have a weak signal or the tab switches to 3G. My phone or laptop hold the signal easily.
The distance is like 5 meters and 3 wals between us. One of them concrete. But my phone holds the signal there, while my tab doesn't. On the other hand my wife's SE Xperia X10 barely holds inside the living room. So I guess android in general is not that good with wireless.

Of course the router matters mate. Instead of guessing why dont you try to troubleshoot... surely logic alone will tell you that its not your tab as a)noone else is having this problem b)your xperia is.

If it ain't broken - don't fix it. This router serves half a dosen of devices. Only android ones are having issues.
My laptop, my wife and my daughter's laptops, my htpc and my son's desktops as well as my phone are OK with it. It is on 100% and no encryption. I have it for years now and it never disappointed me. Why should I blame the router?

For one thing, if youve had it for years it is possible there are firmware updates that will immediately improve the connection of both your working devices and the newer, less backwards compatible android devices.
There are also security frames and CTS overhead to consider. Your router may just be too old to communicate with the newer radios in the android devices. These things happen all the time. Just google wifi problem and add any device you can think of to the end of that... there will be people conplaining about weak signal everywhere, and its usually the routers that are at fault.
EDIT: If it aint broke dont fix it is not an acceptable philosophy for a gadget lover

Well we have several people tried flashing this firmware and it is failing.
Can you be more specific on how you flashed it?
Which PIT file did you use?
Did you select repartition in ODIN?
How is the browser in JJ3? is it smoother than shipped stock?
Thanks.

I've tried a multitude of different settings and it can't even compare to my Nexus One or Galaxy S. Keeps dropping the connection and report a signal strength of about 10%, it's driving me nuts! My current configuration is as follows:
Router: Netgear WNR3500v2
Firmware: DD-WRT v24-sp2 (08/07/10) min
Network:NG-Mixed
Channel:2 (2.417 GHz)
Channel width: 20 MHz
TX Power:71 mW (Default setting)
Security: TKIP+AES

Simply flashed with default ODIN settings and both EUR firmware and EUR PIT-file ( Galaxy Tab / .PIT File: DOWNLOAD. (EUR). I didn't do a wipe before nor did I clear dalvik cache or any such thing.
Can't really tell about the browser, from my point of view it feels pretty much the same.

explanation
The problem is almost certainly your old wifi router having bugs with PSP (power save mode). Android relies on the PSP standard to reduce the power usage on Wifi, your laptop and other old devices probably don't. I've seen old routers disconnecting almost immediately with android devices...
You can try setting "Wifi Sleep Policy" set to "Never" (will impact battery live, obviously). Though there was a bug fixed in ~July where Android would still use PSP, and the tab might not have the fix yet.
But the best fix is to buy a new router. It is broken, standards-wise, and needs to be fixed. Also, newer wifi routers are a lot faster and generally hold the connection better, so its really a no-brainer...

Ditto my brother!

I have to agree... I have two instances of WiFi use with my new Tab:
1) At home, older Netgear router (not that old mind you) - DG834PN - Does 802.11b/g/Super G
2) At work, brand new Netgear router (brand spankin' new) - Wireless N etc
At work, my connection on the tab is consistent without a drop out, fault less and constantly fast. Even the signal strength is good across the other side of the building.
At home however on my older router (no Wireless N) it's slow, signal strength is poor and constant drop outs are present. I need to hit "Retry" on the network connection box so often at home.
So yeah I feel that should be fairly conclusive. The Tab seems to like brand new wireless hardware.

No wonder. 802.11N is much stronger WRT to power since it has 2 antennas. But it is still the tab to blame that it doesn't hold a signal of standard equipment.

Actually, the problem you're having at home is super g. Its not a wireless standard. If it is working in 20/40 auto mode, just switch it to 20 only. This should improve your network connection in general.
Also gonsider using g only - b is pretty redundant by now.

My router lists b and g, g only or Auto 108mbps.
I have had it selected on g only for a while now.

What settings does it have for the super g... does it give you the option of disbling pairing or something like that? It could be the bonding that causes your disconnects.

Is this a normal iconia wifi signal?

Yay so I'm really happy about the iconia so far. The whole no acees to SD card through computer while connected to the computer will take some getting used to, but its the wifi that'll probably get this sent back. It's really bad. I've reset the connection half a dozen times since last night because it keeps hangin and can only downloads app when in the same room with the router.
Now the issue is that I'm laying beside the router now and getting 2 bars. If I sit up I get 3 bars. Yippee. The signal in the bedroom, on the first floor, get maybe 1 bar and I can't stream or download anything in there. I never get a great wifi signal in there', but its between 2 and 3 bars on my phone and netbook,. I wondered if there might be some interference so brought up the handy wifi analyzer and found 4 other wifi signals all on the first channel, so now my router is on channel 11. It didn't help any :-\
So if I exchange it, will the new unit possibly be an improvement? Is this just the way it is?

I noticed that the connection quality drops sharply the further away you are, but atleast on my tablet it still doesn't drop as sharply as in your case. I have the router here in living room and I get 65Mbps, everything works fine. Then if I move to bedroom or kitchen it drops to something around 20Mbps, yet it still works just fine.

What type of router do you use.I have a newer netgear with no issues my router is in the basement at front of house almost under the front porch.concrete ceiling above it. I can go out to my back yard approximately 200 feet and still get 1 bar and OK speed.I do notice. That the indicator bars do not exactly deplict your signal strength.
I also know there is a issue with some routers and the network card in this device I read in a thread long back.you have to turn off n or g feature I think it was.but do firmware update on router as well might help.not all routers are created equally Linksys sucks in my book. Lately
I can also see neighbors wifi signal but 1 bar they are 500 feet. Prob could not connect thou
Wish you lots of luck

hmmmmm
You could have a faulty Wi-Fi antenna ...
More likely, you are using a cheap router or a router with out of date firmware. Have you checked to make sure you have kept your router up to date with the latest firmware?
Also, have you tested this with other routers? If a multitude of routers show the same issue - you likely have a hardware problem with the a500 - if only your router shows this problem, then likely it is a problem with your local router.

a different unit MAY help, but I would try friends routers n such. My router blows but I can still stream Netflix no problem all the way across the house. I can't even do that on my laptop which has a beastly card. +1 for updating your router and device though, that might help.

Thanks for the replies. I have an old Motorola sbg900. I think I bought it 2 years ago. I have noticed that the iconia doesn't see as many networks as my phone does and the speedtest results are interesting. I left everything default in the app. By the router, I get 9 mb/s with the iconia vs 7 mb/s with the phone. In the bedroom, I get. .8 mb/s on the iconia and almost 6 mb/s on the phone. That is a huge drop and gap :'( I'll look up updating the router. I've never had connection problems before and we have 2 desktops upstairs plus both me and my roommates phones and both laptops and the wii and xbox. I just hope I can get some signal improvements on this nifty device.

sounds like firmware or...
I would find a friend with a different type of wifi router and test your connection with it. That way you get a pretty good indication of if you have a issue with your router or an issue with your Iconia.

Bother, my work wifi allows me to connect, but doesn't allow me to do anything with the connection. I am connected, but cannot do a speedtest. Relying only on bars the phone gets all 4 while the iconia gets only 3. The iconia also only sees 3 of the wifi signals in the building while my phone picks up 7 plus an open adhoc network. I know, it's time to visit with some friends so I can do a second test or maybe this is an excuse to go out for lunch today
ETA: At McDonalds, both devices had 3 bars and identical download and upload speeds. I've gone ahead and ordered a cheap $20 wireless n router to see if that improves things. It should arrive tomorrow, but since it's coming via UPS, it may not arrive until Monday.

[Q] G2 WiFi speeds N+AC

Does anyone notice there's a big bug with WiFi on the G2?
I have 2 WiFi ac routers, one at home and one at the Office, an Asus RT-ac66U and a Linksys ea6700. Both capable of 1750mbps max speeds.
Internet speeds are 120/6 and 200/20.
Scenario is exactly the same for both routers;
When fresh reboot the router, G2 connects at a speed of 433Mbps.
Speedtests show results of 119/6 at home and 190/20 at the office.
Great you would say!
But here goes. Once WiFi get disconnected and reconnected, speeds go down to ~40mbps. No matter what I do!
These are N speeds, not AC
When looking at connection settings it still shows a link of 433mbps
Tested dozens of times, on both routers, so it has to be an issue with the G2.
Anyone else noticed the same??
DAMN, should have been in Q&A, mods plz move

I'm not an expert on wi-fi, but have stumbled through setting up several routers around the house. But I do not have an ac router.
Is the home router in mixed mode? Ignoring a/b/c for a moment and focusing on g and n (and implying ac), I have two wireless routers in the house. One runs N only (but both 2.4 ghz and 5 ghz) and the other runs G only. Now, my N router is capable of running in mixed mode (to handle both N and G) BUT in mixed mode, my max speed when connected in N is lower than it would be if I ran in dedicated N mode.
Most of my devices now are at least N (2.4 or 5) but I have an older printer and wii that only do G. But as mentioned above, rather than run my best router in mixed mode, I run 2 separate routers, one in N only and one in G only.
Maybe something similar might help with your ac speeds?

Really appreciate your input!
But I already tried settings like AC only etc. Doesn't make any difference.
Once connected for the second time and up to the router no more AC speeds...

Is there a way to test LAN speeds on Android? I have the same Asus router but my wan speeds are so pitiful that I wouldn't be able to tell if the phone was dropping to N speeds. If I could test speeds to my desktop across the local network I might be able to test what you are experiencing.

Is there a way to check on the phone, which band it's connecting to? I haven't found anything.
I have the same router and my issue is on reconnect. I leave my wifi on all the time. When I get home, it connects automatically the moment I pull up to the house. The problem is, the speed is severely crippled. Range is awesome, speed is bad. I have to cycle the wifi and reconnect. Once done, no more problems.
One thing I should note, I was having the same issue occasionally on my Droid RAZR after getting the ASUS. Does anyone know if they use the same wifi hardware? Maybe it's an issue with the router itself?

Don't know about an app to test lan speeds unfortunately.
Think a google search would come up with lots of options.
@crashN2u
I leave my wifi on too all the time for now, it keeps it at full speed then.
There's no way to check which band you are connected to.
Router doesn't have an option to choose AC Only, only N +AC
And in the mean time I have tested it with 4 AC routers, Asus RT-AC66U, Netgear R6250, Linksys EA6700, D-Link 868L.
With all routers exactly the same conclusion. First time everything is great. Excellent speeds. If you never turn off WiFi it remains at high speed.
But once you turn off WiFi on the Phone and turn it back on it immediately drops to ~36-40mbps max (N Speeds).
This remains until I rebooted each router and after that full speeds again.
It must be something in drivers LG used.
There's the solution to for, I'm sure of it by now.

Well, I can see I won't be much help -- especially since the same result on 4 routers!
I am not sure if the following app supports AC, but a very helpful and free app I use is called "Wifi Analyzer". I can't post links but that is the exact name (author = farproc).
It has many useful tools/functions that you may find helpful, switchable between 2.4 and 5.0 ghz, channel scanner, etc.
Does your 2.4 ghz N and 5.0 ghz N/AC have different SSID's? From what I read, AC is 5 ghz only and N can be either 2.4 ghz or 5.0 ghz. I wonder if you are dropping from 5.0 AC to 2.4 N because the 2.4 N is being detected as "stronger signal" than the 5.0 AC at reconnect time?
I named my 2.4 ghz N SSID as "Blah" and 5.0 ghz N SSID as "Blah_5ghz" just so I know what frequency I'm on at a glance (using a widget that shows the SSID) but many routers by default will have both SSID's the same, making it less obvious what band you are connected to. I also use an app called "WIFI Prioritizer" (author Robert Botha), which will allow me to connect or re-connect in the SSID order I specify: i.e. when I get home I will connect to SSID "Blah" (2.4 ghz N because it has the longest range). Every 5 mins (you can specify), it checks to see if my SSID "Blah_5Ghz" is in range and will switch to it if it is (you can also set signal strength connect and disconnect thresholds).
Anyways, I probably can't help further but am following this thread with interest. Good luck!

My Phone is packed with tools like Wifi Analyser, InSISDer etc etc atm
I always separate 2.4 and 5ghz networks to be able to see exactly what's going on but thanks for the heads up :good:
From further investigation and thinking, and with your suggestion about stronger signals;
Thing is, AC routers are more or less all simultanious routers.
That combines 2.4 and 5ghz signals for higher transfer speeds.
I think in there lies the problem when drivers are not 100%.
In theory 2.4 signals are stronger then 5ghz signals and have wider range.
But in testing I made sure that I was in the same room and no more than 2 meters away from the router.
when testing it showed equal signal strength up to -20 so really strong signals.
Therefore I concluded that N on 2.4 whas equally strong as 5ghz and then again I isolated 5ghz SSID so that's not it unfortunately.

I promised to stay away but I can't resist!
Have you tried some of the more generic troubleshooting tips (on the home network), such as trying with no security or lesser security (WEP) to see if it still reconnects at the lower (N) speeds? I realize that usually that test is of course for a more basic issue than yours but maybe the G2 has trouble handling security overhead.
Some devices and routers just don't like each other (as many know), but 4 different routers...?! Gotta be the G2 side, as you've surmised. Wish I knew someone with an ac router so I could test myself. I'm debating on getting an ac router but you've got me spooked! (kidding/teasing)

Well haven't tried lower or no security.
When I have the chance (aka the wife is away and not *****ing about wifi not available ) I'll sure try that.
But I don't think that WEP will be an option because AC requires AES protection if I'm not mistaken.
But really do not be afraid to get yourself an AC router hehe.
No honestly, I've tested 4 routers with:
AC Capable:
HTC One. Goes all the way to max isp speeds. All the time, no issues
LG G2.
Not AC Capable.
IPhone 5. Max speed at 5ghz (constantly tested) is ~90-100mpbs.
HTC One X. Max speed at 5ghz (constantly tested) is ~70-90mpbs.
So even if your hardware maybe not be capable of AC speeds you still get excellent connections
Oh and for the record.
Here's my personal listing of the hardware I've tested. From best to well not so good.
1. Netgear R6250.
Excellent constant speeds. No drops whatsoever with around 6 devices connected. Excellent range!
2. Asus RT-AC66U
Shame Asus introduced a new wifi driver some time ago which doesn't perform that well. Constant speed drops.
They know about it but thusfar no solution.
When you get this one, stay on old firmware for now!
3. D-link 868L
Real looker this one. Can be put in plain sight in the room like a picture frame :silly:
Great constant speeds, but some drops here and there.
Excellent range.
4. Linksys EA6700
Linksys is sold to Belkin by Cisco.
Up to now I have never seen anything good coming from Belkin!
What a piece of crap.
With a really thin wall between router and phones coverage went down more dan half. Hell even when distance less than 2 meters away coverage was about -45.
Do not get this crap!

I wonder... the wireless N spec (not sure if also AC) calls for devices and routers to have a 'low power mode', which may or may not be enabled in routers and/or phones (e.g. GS3) by default. According to some article I read, newer routers may go into a power saving mode if it detects low traffic and supposedly ramp up when the traffic increases.
Possibly it doesn't ramp up fast enough when a new device connects and the device mistakes it for not having the highest speed (AC) capability. Might explain fast speeds after router bootup but not later. If there is any truth to that (no clue here), it might speed itself up either by testing with a larger file or seeing if the "2nd connect" condition changes while say, streaming videos from the PC to the Xbox or watching Netflix on the main TV. Certainly, either would be considered high traffic and if there is no change to the 2nd connect, well -- there goes that idea.
Is there a wifi power saving mode on the G2 like there is on the GS3? (i.e. dialing *#0011# to turn it off).

Good point!
Well, there is a setting in wifi, advanced to minimize use of wifi when screen is off. Sounds like a power save mode to me.
But, just tested it and that makes no difference.
With that setting deactivated on the G2 still at first boot AC speeds and when I switch off and on wifi I still get N speeds max.
And besides that, on the Asus router there's a setting called "Enable WMM APSD". Which stands for "Automatic Power Save Delivery".
I read up on that and the custom firmware guru RMerlin writes about that setting that especially Android devices could suffer from that setting.
So I disabled that a long time ago.
On other routers I couldn't find such setting.
But to iron that setting out I just tested it once more.
First with setting off. Still first connect AC speeds, after turn off/on back to N speed.
Then turned wifi off, enabled the setting and rebooted the router.
But this time to let the supposedly power save kick in I let my Phone idle for 15 minutes so that it surely was in deep sleep.
Then turned screen on, and again AC speeds when first connected.
After that turned wifi off, screen of for 15 minutes. Turned screen on again and once more N speed.
And link speed is always shown as 433mbps btw, which is correct.
There's just some bug in driver code by LG which doesn't work correctly.
I'm more and more convinced of that.
For now I just keep wifi on all the time so that I always get full speeds.
Batt is capable enough so no problem there

I found a tool to test local network speed. It uses two android devices for a p2p test or you can install a server program on your PC. I'll do some testing and see if I can reproduce what you are seeing. Here's the link: http://pzoleeblogen.wordpress.com/2013/08/12/local-network-speed-test-for-android/ and the market link: https://play.google.com/store/apps/details?id=com.pzolee.android.localwifispeedtester&hl=en
And to be sure I understand, you boot your phone with wifi on, AC speeds. Turn off wifi on phone and turn it back on, N speeds. Reboot phone with wifi on, back to AC speeds. Correct?

And to be sure I understand, you boot your phone with wifi on, AC speeds. Turn off wifi on phone and turn it back on, N speeds. Reboot phone with wifi on, back to AC speeds. Correct?

Thanks for the app!
Gonna test this for sure since I also have a HTC One lying around which is also AC capable
Not 100% corect.
I can do with phone what I want until wifi gets turned off.
Then a reboot of the router is required to get AC speed back.
No need to reboot the phone.
Quite busy atm so don't have enough time I would like to be testing

Between my wife on her laptop, my son on his Chromebook and my daughter streaming Netflix on our Roku, I hardly ever have a chance to reboot the router without someone complaining
Since I haven't rebooted my router in days, from what you are saying I shouldn't see anything above N speeds until I reboot the router. Do you actually have to turn off wifi on the phone to have it drop from AC to N or is it enough to leave the range of the wifi and then come back? And does if turning it off is required, do I have to be connected to the router at the time I turn phone wifi off?
I'll try testing this weekend.

Going out of range isn't a problem as long as you don't have an app or setting on in wifi, advanced to switch off wifi.
As long as wifi isn't turned off I can go everywhere, in&out of range, other routers connect but speeds remain AC, everywhere on every router.
I can reproduce everytime that when I turn off wifi on the phone and back on from then on I only get ~36-40mbps max.
It's like the phone thinks that's max capable speed altough wifi link speed is again shown as 433mbps.
If I have switched off wifi on the phone and back on, on all 4 AC routers I tested all needed a router reboot to gain full AC speeds again.
Oh and maybe a small tip, I always say to the misses at home that there's a small problem with connection so a quick reboot is required.
Up to now that still works

I just did a few tests from my phone to my pc with 100MB data sets. I got between 200 and 260 Mbit/s down both before and after toggling my phone's wifi off and on. Didn't seem to make a difference. I got about 6Mbit up.
So, I didn't seem to experience the problem you have. But try repeating what I've done with this local network app. Maybe you won't have the issue with it that you are seeing on your WAN connection.

Wow and do you really see real transfer rates of 25-30 MB/s to your G2?
I'm using a Qualcomm Atheros based AC-router and my G2 (running latest CM11) hardly goes over 10 Mbit ~ 1,5 MB/s. Weak I know. (Confirmed 433 Mbit link using a wifi app.)
Maybe I need a broadcom-router like yours to see some real AC-speeds.
Thanks for the reply. Take care

horrible WiFi strength ruining Nexus 10

Can anyone confirm or not if the crap WiFi strength on nexus 10s is an acknowledged fact? I have seen some say it is, yet still see other comments praising the devices WiFi saying it is stronger than ipones etc.
This is my second N10, I sent the first back due to WiFi performance and I believed it to be defective. My second devices arrival has suggested otherwise as I have noticed no improvement.... Am I just really unlucky?
On my home network, every other device has ho WiFi issues, but my n10 struggles! It seems to sho a decent signal strength in the WiFilist in settings, but a low strength in the top right corner.... Can anyone advise? I get similar strength issues on other networks (public and at friends houses. SO frustrating not being able to perform one of the most basic functions on a £300+ device). Was hoping 4.3/4 upgrades would help- nothing.
Should I get a third nexus sent out? Is this down to poor quality components? Anyone having same issues?
Thanks!

Hard to generalize, but mine has been rock-solid (on 4.3; I'm holding off on "upgrading" to 4.4). Seems to give faster throughput than my N7

My N10 seems to be at par or a bit better than my better halfs Ipad. Taking both tablets and going for a walk out in back (acreage), in the outbuildings, and near fences, the signal strength and ability to connect to my router and see other routers was actually a touch better with the N10.
When first getting the N10, it did seem to drop the wifi signal, but replacing the el cheapo several year old router with a newer medium price router cured that issue.

The Google Nexus 10 as well as the Amazon Kindle HDX are two of the few devices that actually support MIMO (multiple input multiple output) wireless.
This typically allows for very solid and swift wireless performance.
I suspect that software updates may have had some impact on the Wireless functionality of the Nexus 10, but that is also in combination with some types of access points, so it varies to each customer.
Some places I get really terrible wireless, but at both my work and at home, it performs extremely well.
Hopefully a future KitKat patch will address the wireless more. I notice that new binaries are included in KitKat pertaining to both wireless and Bluetooth for the N10.

Hello, I just became an owner of a Nexus 10. when I first time connect to my BSNL Teracom wifi router it is not connected. it is always showing connecting or obtaining IP address...
It connected through my S3 Hotspot but not through teracom router
I wake up in the morning and just press again the connect button. Bingo...it is connected..!!! Not understand why it is behaving like this. I am not done any changes in routers settings also. Is it not connecting b'coz the routers frequency mismatch or anything else ?? After once I switch off and on the router the same problem happens
all my phones including a Samsung s3, tab neo and also my laptop all are switches automatically connected to the wifi router.
Please help.
thanks in advance.

Yup... Crap WiFi on my nexus 10 too. Just randomly disconnects or is so slow that its unusable for streaming movies... I own a ton of android devices and this is the only one that gives me problems. When I turn it on, I just hope it stays connected. Let's hope this post goes through lol

Mine pulls 40mb out of a n wifi connection.. the main connection is only 50 -55 on average. I'd say its the best performing wifi device I own.

I have owned my N10 for over a year. The WIFI signal strength is good, but I often get some lag issues, which ended up being my router. When I have issues, I now reset my modem and everything works again. I have read that some people only have a 2.4GHz modem, and they have received better luck by limiting WIFI to that frequency only.

Link found to WiFi 5GHz problems

So like everyone else I have the 5GHz wifi problem. If I'm not in the same room as the router you can forget using 5GHz. So I found the link to the problem. I just don't know how to solve it. I connected to the 5GHz in a trouble location while having mobile data and Bluetooth turned on. Internet speeds were terrible to the point the speed test would barely run. I turned Bluetooth off, and the speed test are right on par with my old phone, and 5GHz is working fine while Bluetooth is off.

5Ghz is not meant for long range though, 2.4Ghz takes care of that..
You should be able to obtain a signal within around 30feet, potentially more, but it'll drop off at that point.
2.4 carries a lot better..
Could it be to do with the channels that the phone may be using for WiFi??
Turn off all WiFi devices and Bluetooth in the room and see how the test goes.
Very strange.

I am a bit confused as to why people are reporting needing to turn BT off to operate 5GHZ Wifi. BT operates in the 2.4xx space. If you are saying turning it off resolves your problem this points to either a greater hardware/software issue or that you are not operating in 5Ghz at all.

I understand how 2.4 and 5 work as far as range and bandwidth goes. I tested this theory in the same spot my old phone would get 100mbps down (what I pay for) while connected to 5Ghz Wifi. The OnePlus 8 Pro while connected to 5Ghz in the same spot with Bluetooth enabled would cause the phones speed to drop to around 5mbps down and sometimes to the point I get nothing and losing connection. Now if I repeat the same scenario but this time I disable Bluetooth the connection is stable and speeds are 90-100mbps down. I repeated this multiple times sitting in the same location. Yes I understand that BT uses 2.4Ghz. I'm not saying that you need to turn BT off for 5Hhz Wifi to function. What I am saying is some how on this phone, and reported by others, the 5Ghz Wifi on this phone does not function properly. There have been zero solutions or reasons why that I am aware of. My post was pointing to a possible reason why and the fact that it is a hardware/software problem and maybe the right person could look into. I have no reason why the BT being on and off affects the 5Ghz Wifi on this phone and not the 2.4Ghz but it does. And my old phone was a $300 Samsung A50 that I was testing this phone against in my post. I tried to find what channels the phone uses for WiFi but was unsuccessful. If you find the channel lost I would be more than happy to switch channels and see.

It ends up it is an issue with the channel. Before I bought the phone I had manually set my router to channel 153 because auto kept putting me on the same channel as my neighbor. The OnePlus will connect to channels 149 and 153 but isn't really functional. I had to select one of the UNII-1 Channels. Once I did that 5Ghz worked and is functional and stable. The sad part is the reception isn't nearly as good as my $300 Samsung. Maybe they'll improve that if they can. I'm still bewildered why turning off Bluetooth allowed channel 153 to work.

Turn on auto channel on your router. You're going to have issues unless your entire network and devices are moderated perfectly.
Auto does the job
