5.0 5Ghz Wifi Issues

Did a full image wipe/install with the official 5.0. I'm no-longer able to connect to my Netgear r6800v2 router with the same channel 48 setting for 5Ghz that previously worked on android 4.4.4.
Any other folks out there with android 5.0 problems using 5Ghz channel?
EDIT: I should add - I'm fully aware the N10 has limited 5Ghz frequencies it works on (e.g. 40, 44, 48) - I've tried 36, 40, 44, and 48... none of these seem to work in android 5.0 with the same router settings. It can see the broadcast and attempts to connect, but IP address is never acquired (DHCP)

I'm having the same issue and my 2.4 network is very slow. Anyone else have this issue or any idea how to fix it.

Yeah I've had issues with 5ghz on every lollipop device I have. Haven't figured out how to fix it yet

I had the same issue and changing to Channel 44 (with Auto bandwidth = 40 mhz) solved it for me, it was on 36 initially

No problems here, did a clean flash of Lollipop and 5GHz is working fine with my RT-AC68U, channel 36, auto bandwidth.

Same problem here. Changed to channel 44 and is at least working

Wiped. Clean flash. No problems. On channel 157. Wish it would tell me if im 300mbit or not. Ac n66u.

Installed from a sideloaded OTA.
Have issues connecting to my Virgin Superhub 2 both on 2.4Ghz and 5Ghz.. Channel 8 and 36 i believe.

Go into Settings -> Wifi then tap the connected wifi network. It will tell you your link speed there. Mine is connected at 300mb/s, while in powersaver mode it drops to 24mb/s.

Mine only connects at 24Mbps and its not in powersave mode

I've similar issue, but both on 5ghz and 2.4ghz.
The connection isn't stable and I get disconnected all the time after upgrading to lollipop. If I'm tethering with my phone right next to the tablet (on 5ghz) it works perfectly. I'm not sure if they've tweaked the disconnect/reconnect threshold base on signal strength.

I'm having problems with 2.4 Ghz wifi too. In Jelly Bean I have a pretty good coverage with my home router but with Lollipop I get lots of disconnections and slow speed. I'm not sure if it's a drivers problem or an operative system change, but I know for sure that it's a pain in the ass.

I'm having the same problem with 2.4 Ghz.

Both 5 and 2.4 are much worse for me as well compared to kk.

I've solved my Wi-Fi speed problems changing one setting in my router: just disable WMM ( Wifi MultiMedia).
Try to enable/disable that setting (can be shown also as WME instead of WMM).
Good luck!

My 2.4g is working perfectly, but it cannot see my neighbours 5g network. My Note 2 sees it fine. I checked with Wifi analyzer app.

I can connect to my BT home hub 5 but it only works for a free minutes and then it kind of freezes.
I'm still connected according to my tablet with good signal strength but there is no internet activity making the tablet pretty much a big paper weight for me at the moment.
If some one can help me fix this issue id be very grateful

Connecting just fine at 5GHz 300Mbps with 5.0. I have tested 2.4GHz as well and both function just fine.

I do connect easly, but connection quality is poor... There is definitely something wrong with Wi-Fi on lollipop

No 5 GHz WIFI found after first installation

Hi,
I got my X play XT1562 (french dual sim) just yesterday and when I first started it I was able to connect to my 5 GHz WIFI. Then the backup was restored by this default android function from my Moto G. It seems to have restored some WIFI settings since it knows my 2,4GHz WIFI passwords. However, the phone now does not een see the 5GHZ WIFIs anymore.
Anybody with the same issues? Any ideas?

Try resetting the network settings from backup and reset in settings.

The obvious one to try is change the 5GHz channel on the router, probably not that but it wont hurt to rule it out.

So true it was, thanks. It seems immediatly after the first start after a reset the WIFI can be seen, but no connection is possible. Staying on this screen 1 minute afterwards the 5GHz WIFI spots are gone.
I found out my router was configured as region US even though living in GER. Once I chose a channel which is available in Germany too, this 5GHz net can be seen on the Moto X.
Thx for the hint.

Mobile Hotspot - 5 GHz issue after upgrade from Android 6.0 to 7.0

Hi All,
I would be grateful if somebody could confirm for me one thing. To be precise, i am not sure if there is a bug in the stock firmware regarding the mobile hotspot that worked on 5 Ghz while i was on android 6.0 (that was originally installed when i bought it) and by some reason does not work on Adndoid 7.0.
Do not understand me incorrectly, wifi works fine on 5Ghz, i can connect to wireless access points that broadcast on 5 Ghz whiout any problems.
The problem is that when you switch on mobile data and then trying to switch on mobile hotspot to broadcast your phone on 5 Ghz it does not work. When you change it to 2.4 Ghz in the configuration settings of the mobile hotspot, it works. So no more hotspot on 5 Ghz on Android 7.0? It worked on Android 6.0. What a downgrade!
Or its the bug? Can someone test it and reply? Or may be Verizon made it in purposely?
My phone is 930V and it is not rooted with the latest firmware from Verizon. And i am using it outside of US.
I searched the internet for this issue and noticed that people had the problem with wifi module itself after upgrade to 7.0 but they could not to connect to wifi access points on 5.0 Ghz at all. And that problem they solve by doing factory reset. In my case everything is ok with the wifi module. It connects to my wireless access points that work on 5.0 ghz with the speed of 866mbs. It is just mobile hotspot can not be switched on using 5ghz.
By the way, I made factory reset and all available resets and this does not help. Of course it will not help, because i have different problem. I believe that Verizon in purposely made this. But how to correct that? Is that possible at all?

hm it might be a bug, try downloading Foxfi and give it another go

Latest update breaks 5 ghz wifi

So I finally figured this out - pre the latest update 5 ghz wifi on the Oneplus 6t worked flawlessly. Then the latest update came down (ironically over 5 ghx wifi) applied and rebooted and poof 5 ghz wifi no longer works. It connects, it gets ip, it can see the router everything looks normal but if i try to go anywhere on the internet - it tells me i am off line . 2.4 ghz wifi works just fine but the 5 ghz is broke. It took me a while to find this because I would auto switch to wifi at work and at home and didn't realize what was going on. Playstore would not download, app updates never came trhough. If I turned wifi off it all worked but then I am eating my data plan. Just an FYI to anyone having odd issues suddenly.

Weird. Mine still works fine on 5 GHz after 9.0.11 update (8/256 OP direct, totally stock unrooted).

On 5ghz as well. I've had no issues at all after any of the updates. On 9.0.11, unlocked/rooted.

No issues with mine on 9.0.11.

I have they same problem!

I have the same issue.
For those, who say it works, turn mobile data off and try to browse on wifi 5ghz...

Turned off mobile, still able to browse on wifi 5ghz.
Turned off mobile and wifi. Reconnected to wifi 5ghz. Still able to browse.
Turned on Airplane Mode. Reconnected to wifi 5ghz. Still able to browse.
Sorry. Can't reproduce issue.

For those that it works on 5 ghz - what band is your 5ghz on - if you check your wifi under network details see if it says 5 ghz or defaulting 2.4? (some people have combined wifi that will place you on what ever network is fastest) - also if you could show post your link speed (show on the Oneplus 6t under network details for wifi

Actually - I did a quick test and I could be incorrect. I set up a guest network with 5 ghz no password and got on it just fine and can pull 400 Mbs. My network password is complex so that might be what is causing the issues . I am going to experiment with a shorter password to see if that fixes it - but that would be a shame if that is the fix as it worked just fine before.

On tmobile, unlocked, flashed through twrp, no issue 5ghz as far as i can tell.

So I experimented more. Here are the results. No matter what I did to my internal wifi I could not get a connection on 5 Ghz. No issues on 2.4 with a long pw, a short pw- aes or tkip wpa or wpa2. But cannot, will not go anywhere on 5 ghz. Here is the odd thing. I can set up guest wifi on my router so I did. I set it up with no pw and boom, 2.4 g, 5 ghz1 and 5ghz2 - all of it. Then I turned on wpa/wpa2 and encryption (auto/aes/tkip) and set a password...and boom. Still working?? Exact same set up internal Wifi - nothing same issues. It's Bizarre. I turned off all the fancy settings for internal wifi like link sharing, fastest connection - I separeated them out to 2.4g/5G1/5g2 just like my guest and ...nothing. I can connect all day long but it just cannot get to anything on the internet. So for now I guess I am stuck using my guest network.

To the others who said they have the issue - what brand of router? - Mine is the TP-LINK AC5400

working fine here, verified that 5ghz is connected in settings

This sounds like it's a DCHP server issue with your router.

can't be - dhcp is band agnostic and it works - I get an ip address on 2.4 and 5 ghz just cannot get anywhere on 5ghz when using my home internal router set up - plus when I set up guest network on the same router I am just fine. And it worked just fine before the latest Oxygen update (that and I have about 18 devices on wifi all working just fine - including my oneplus 6 running the same Oxygen update - ) Has to be a bug of some kind.

Same problem here, oneplus 6T and Oxygen 9.0.11. I have this bug since update from 9.0.10 to 9.0.11.
I'm not on TMobile (see on reddit about oneplus_6t_update_breaks_google_play_certification), i'm in Italy with TIM operator.
I have problems with Fastweb Fastgate Router (Askey RTV1907VW), wifi 5ghz is connected but i can't browse, i can't do a speedtest from App on OnePlus 6T, etc.
But now in my office, i have a Vodafone 5GHz router, and i don't have any issue!
Could be a problem of the "channel" for 5Ghz wifi connection?

oneplus 8 pro wifi/bluetooth issues (with a tmobile sim)

So I may have come across something that may help someone else out as well...
Recently (as in less than 15 days) purchased a oneplus 8 pro from oneplus.com. When I first got it it was on android 10 and I was not able to connect to either my 2.4ghz wifi or my 5ghz wifi using WPA2. I had a oneplus 7 pro previously that still connects without issue. I had read elsewhere that the open beta was better so I tried that and it indeed was better but sometimes though I was connected to the wifi, no traffic would travel over the network and it would stall to the point that the only way I could do anything internet or network related was to go to my cellular data. I did the 'device mac' as opposed to random mac and that helped for a brief time however that even cause the same stall/lack of response issues.
Since I don't have much for 5g cellular where I am, I changed it to only look for 4g....still no improvement. On a whim, I disabled any and all security on my 5ghz wifi and low and behold I could connect. I wasn't about to leave either of my wifi networks wide open but also remembered the network I connect at work is also not wpa or any sort of protection so theres a hint as to how to 'fix' these issues. I then read someone about the possibility of having special characters in your wifi password can cause issues. I removed the ! in my old wifi password so it is now alpha numeric and have had no issues with my 5ghz wifi network. I have been able to stay connected with my 5ghz wifi WHILE bluetooth has also been abled and the speeds are roughly normal.
Try at your own risk but in summary:
1. upgrade to the open beta 2
2. disable 5g cellular connections
3. connect to your 5g wifi and make sure the password has no special characters in it as well as use device mac NOT randomized mac
4. perhaps success
With all the above being said, I do still intend on sending this phone back in hopes that I got a dud unit but I'll admit seeing these results makes me feel like its more of a software issue and certain incompatibilities with certain routers.
Just dropping what info I have discovered in hopes it helps someone out there...I would not normally endorse using NO password on wifi or a weak password, but for this phone it may be a requirement at least until the updates can come into play.
Thanks,
E|

I am backing everything up to go to Android 11 tonight, and I switched to a new WPA2/WPA3 router here, but my password has no special characters.
On Android 10, complete nogo, as using WiFi calling with a BT headset on 5ghz slows the network down so much, the other person can't hear you (no upload bandwidth).
I'll let you know how Android 11, OB2 works out for me.
If there are issues, I am going back to the OnePlus 7 Pro and selling the OP8 Pro.
Since I have not been using WiFi, I blew through 55Gb of data this month already so am subject to throttling, thanks OP8 Pro

You could try om a different router of someone else to pin point out if it's your router yes or no.

I did upgrade to OB2 a few days ago and wifi is generally better. But VOWiFi never works with a bluetooth headset - the other person can never hear me.
Also when streaming over WiFi the connection drops or stalls and causes rebuffering. I have confirmed these behaviors with 3 different routers.
Can anyone on TMobile (USA) confirm working VOWiFi while using a bluetooth headset?
Also 4G and 5G speeds slow down when on a call using bluetooth.
Maybe this is all due to qualcomm 865 chipset issues as the galaxy S20 users are having similar issues?

I had faced lots of stability and speed issues on the 5gz band. Received the OS11 update today and my issues seem to be resolved. So far the 5gz connection has been very stable, lightening fast speeds.
