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 don't care whether you delete this topic or not. It is, somewhat, development related. I'm just doing a new topic for this thing because, if I were to post this on a ROM thread, it would have become covered with 100 other posts within the hour, decreasing the chances of the developer reading it! My hope, with this thread, is that someone interested or someone who knows about this, sees it and does something about it! Please read first, and if you, the one who has the power to delete threads for whatever reason, consider it utterly useless and retarded, delete it.
I'm a new DHD user (switched over from the Desire). This issue was in Sense ROMs for the Desire, as well. The Desire S had this problem with stock GB, too.
In CM-based ROMs such as MIUI (which is what I'm currently using), you get an "Advanced" section under Wireless Networks. From there, you can choose the wi-fi channels (11, 13, 14). On a freshly flashed MIUI, no channel is selected. I have two wi-fi networks in my appartment (one is mine, one is from a neighbour). That second wi-fi network, from my neighbour... my phone does not see it (unless I choose 13 or 14 wi-fi channels).
Funny thing. That neighbour's wi-fi... it's set on channel #3. It's a MSI RG54SE II router, if that matters.
Now, on Sense ROMs, such as Android Revolution HD and RunnyDrOiD (the ones I have tried so far), you don't get the option to choose the channels. So... that RG54SE II is unseen by my phone.
Back when I was having the Desire... Only LeeDrOiD ROM had that "Advanced" section under Wireless Networks. Not sure if that's the case with his ROM for the DHD, as well...
So, this thing is not only for the DHD. It's also for the Desire, and the Desire S. My gilfriend has a DS, and until I convinced her to let me unleash her phone's lockers and flash something on it, she could only see 3 Wi-Fi`s (stock 2.3.3, that is), while I could connect to all 20 that were available in the zone.

Hope you get my point. Hope you know what I'm talking about. Hope I'm not the only one that noticed this!!!
If anyone has any idea on how to solve this... please tell me. I have tried LeeDrOiD's "Adhoc networking" (that was the only network-related addon I could find, so...) patch, but that didn't do the work. I don't know what will, since there isn't any addon for this... or I'm blind? Open my eyes, then - KINDLY, not with a banhammer.

This is not the answer you're looking for, but it's worth a mention. You should just ask your neighbor to use a recommended channel. I notice that you're outside of the U.S., where you are supposed to use channels 1, 5, 9 or 13 to prevent wi-fi networks from interfering with each other (within the U.S. you are supposed to use channels 1, 6 or 11). You can make up a story and tell your neighbor that his oddball channel 3 configuration (that he probably decided to use for no good reason) is causing interference with your own network, and you have the technical proof to back it up. From Wikipedia:
"There are 14 channels designated in the 2.4 GHz range spaced 5 MHz apart (with the exception of a 12 MHz spacing before Channel 14). As the protocol requires 25 MHz of channel separation, adjacent channels overlap and will interfere with each other. Consequently, using only channels 1, 6, 11 is recommended in the US to avoid interference. In the rest of the world, the four channels 1, 5, 9, 13 are recommended."
Maybe you can just get your neighbor to follow the rules and switch his network to channel 1, 5 or 9. Then every ROM that you use will have no problem connecting to his network and the problem is solved. I'm assuming you have his permission to use his network resources.
Both my Huawei and his MSI router are configured to channel 3. I put it to that, because there are other 10 networks within this area, and I thought... meh... perhaps they're not using the same channel, lol. Anyway, with the phone, on 14 channels, I only see 5 networks, including mine. With the laptop, I see about 11, so I believe this applies to whatever networks there may be outside, too...
The neighbour I'm talking about... I don't have his permission. I think it's one of those 50 year old couples who don't give a **** about what hardware the ISP installs in their home. Most older-than-45 people here, in my country, know nothing about Wi-Fi, and, since they don't even use it... I wouldn't be surprised if the people who own that MSI router don't even know it's there.
Anyway... the gateway, interface, whatever (192.168.1.1) is accessible, and the user/pass are not changed ("admin', that is). It ain't got a password, neither, obviously. So I could get in and change everything I wished regarding WLAN. Too bad it ain't got /n, but still... I'll try to change the channel even further, and try again with a Sense ROM.
Still, that doesn't fix the issue. Downtown, the most crowded place in the entire city... there are about 25 Wi-Fi networks around (at least that's what I can detect with my phone). My phone (CM-based ROM) can see them all. My girlfriend, with her stock ROM`ed Desire S, could only see 5 or 6. That is no longer the case now, since she's got MIUI, too. And I believe this is the issue with all Sense ROMs : you see 30% of the WLANs you'd see with a CM-based ROM...
I can't ask public stores : hey, your wi-fi... it's set to a channel that my phone just can't see, change it!

@Formhault - You risk Jail if you violate the neighbors privacy. It's like you found on the street a wallet full of money and you don't gave back to the injured person.
I posted a thread just like this before and it passed rather unseen. And un touched. Also I asked for a similar situation and had negative answer. But my issue is that I have a VIZIO router.
This is a rather new router and it gives me another option VIZIO HD. Which is more advance and speedier. I have a 12mb connection but I dont have full speed as I cant connect with this.
And a samsung galaxy can also a motorola atrix so I would like to know if someone knows if this can be modified.

Firstly, using a persons WiFi without permission is theft, regardless of whether it is locked or not. Does an open window in someone's house mean you can legally steal there belongings?
Secondly, this is not Development related in the slightest.
Thirdly, you want the XDA community to help you find a solution to break the law? You should search for an answer elsewhere. i.e. not XDA.

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.)

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.
Hi all, just picked up a Tab S5E today - love the screen, built quality etc. What I don't love is the Wi-Fi performance. I'm left very confused.
I installed Android 10 right out the box and did a clean reset - after which my link speed in Wi-Fi settings shows 86 mbps throughput. For reference, my other phones (Oneplus 5 - 3 years old and Oneplus 8 Pro both show 866mbps receive and transmit speed).
When right next to the router I get a max of about 150mbps, with an average of 80mbps on Speed Tests - This is the case whether holding the tablet or not. When about 5 metres away through a wall this goes down to 45-55 Average, in comparison both phones show around 280-330 average.
When right next to the router with my other phones I get my networks full download which is 550mbps.
I understood before purchasing that if holding the tablet in the bottom left corner when in horizontal position (camera on the left) you are likely to lose signal - potentially mitigated with using a case. However, by wrapping my hands round the left antenna, on average - the speed increases to around 150-170 - odd...
When attempting to put pressure on the antennas from both ends and firmly wrapping my hands around the tablet, I do not see any network connectivity issues relating to dropouts and the WiFi bars remain on 5.
Honestly not got a clue what's happening here, either who have decently fast connections don't big this up online, or this is just a weird hardware fault with my unit.
Pretty disappointed. If anyone has any advice / screenshots of their speed results higher than this - I would greatly appreciate this, in which case I will definitely pursue a replacement device. I can't accept that in 2020 a device cannot achieve full 5.8ghz WiFi speeds when directly next to the router.
There is nothing wrong with your device. The maximum WiFi speed on the Galaxy Tab S5e is around 160 to 180 Mbit/s. I didn't expect this either when I bought this model and it is also a major bummer for me.
The device supports 802.11ac, but unfortunately Samsung only put a single antenna into it which limits it to a single MIMO stream (on a 80 MHz channel that gives you theoretical 433 Mbit/s throughput, which of course no device will ever reach). I would expect something around 220 Mbit/s with this configuration, but somehow the maximum speed I get with this device is only around 160 to 180 Mbit/s. It is not only the speed that is bad, it is also the signal strength that is exceptionally bad compared to all my other devices.
Your phones and other devices probably have two antennas and support 802.11ac with 2x2 MIMO which gives you theoretical throughput of 866 Mbit/s and around 500 Mbit/s in practice.
Thank you for your reply. I just received a replacement unit and tested before updating to the Android 10 update. There was indeed something wrong with that previous device as the link speed shows 433mbps and I consistently got 280-295mbps download.
However, I just updated it to Android 10 - now it's completely gone again. Link speed 87mbps and downloads of 20-70mbps. This is most definitely a software issue which I'll be contacting Samsung about.

I also got a WiFi issue when upgrading to Android 10. My tablet was working perfectly before the update but now will not auto connect. I agree this must be a software issue.
I have just upgraded my tablet to Android 10 and the Wi-Fi speed maxes out at 60 Mbit/s. I'm thinking about selling my device again, this is unusable.

All I can suggest is to create a bug report in Samsung members app. I did so over 10 days ago now and am awaiting a response. The more people that do so the better - a fix needs to be rolled out for this. Something's quite wrong with how the WiFi module is working after this update, probably driver related.
Has anybody tried wiping the cache partition in Recovery Mode? If that doesn't help back up your device and perform a Hard Factory Reset. That normally fixes any software issues.

With both the tab s5e's I've had I had reset them both twice, and cleared cache in recovery.
This is definitely an issue brought about with the update considering Android 9 was absolutely fine network wise.

In that case you may have purchased a unit from a bad batch.

I disagree, this is definitely a new problem that was introduced with the recent Android 10 upgrade. Samsung made the Wi-Fi signal "more stable" by limiting the modulation type to QPSK (MCS-2) instead of 256-QAM (MCS-9) which effectively caps it to 87,8 Mbit/s on a 80 MHz channel. Instead of 180 Mbit/s with Android 9 (which was pretty bad), users are now getting around 50 Mbit/s (which is incredibly bad).

My S5e won't auto-reconnect following the recent upgrade to Android 10. Also stutters and freezes for a while after restarting in various apps and settings. System software issues presumably.

Thanks for doing the research to find this out. This definitely explains exactly what I'm seeing.
Very disappointing as I was achieving fine speeds 290mbps or slightly higher prior to the update. Now WiFi on the whole is pretty poor in comparison.
Why was this done intentionally - it really makes no sense. Surely this must get reverted.
I just got an update this morning aimed at WiFi improvements

I can confirm this update has fixed all issues for me. Normal 433 link speed when next to the router and the same WiFi download speed as on Android 9.
Since updating to Android 10, I started having issues with mesh wifi (I'm using Google Wifi). Same position and setup that used to work perfectly with Android 9, now the table starts disconnecting from Wifi and I have to reboot to reconnect. Anyone else has this issue?
I'm contemplating buying an S5e tablet (in Australia). Does the reduced speed of WiFi impact on any practical applications ? My internet cable subscription is for 50mbps. It used to be 100mbps, but I dowgraded on purpose, seeing no benefit for the cost. Even at 50mbps (practically 46) we have moments like today when both myself and my son are working remotely to different employers, while my wife us watching a video. I realise there could be apps which require more bandwidth, so I'm just curious what those might be.

That is exactly my problem as well. Google WiFi and random disconnects from the tablet that sometimes get fixed by disconnecting/reconnecting but majority of the time a restart is the way to solve it.
No other device in the household gets disconnected from the network (neither was the tablet before upgrading) so it is definitely the update to blame.
Having similar issues following the update. I tend to turn the tablet off when I'm not using it, and thus far I have yet to successfully connect to WiFi on startup. I have to manually toggle WiFi to get it back on.
Same wifi issue here after updating to Android 10. Is there a way to manually update using file some were receiving in late July?
I am really bothered by this GROSS limitation too! It makes issues with the driver even worse.
Maybe our answer can be found on this page or something or nothing ?

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.
