Wi-Fi wont turn on - OnePlus 7T Questions & Answers

Hello! I've just rooted my OP7T and Wifi wont turn on, however data connection works fine. Any idea as i cant find a relevant thread, if there's one please link and close this :v sorry if i ruined any rules!

No wifi after rooting is usually due to flashing the wrong OOS version.
Did you follow the steps here?

jeez man, first, learn some punctuation.
did you update the radio? you should have. go to the development section and find the thread with 'radio' in the title. follow the instructions. then try to get onto your network.
and, you may check your settings. it shouldn't affect your wifi connection, but if you're roaming, the data connection will be off, if it is set that way in your settings.
thanks i'll try it.
do not know how to go past recovery part please help.

[Q] WiFi error after flashing WiFi N

So, I flashed the supposed fix to get WiFi N without reading the entire thread...
http://forum.xda-developers.com/showthread.php?t=707218
After doing so, my WiFi just says "Error" when I try to turn it on. I then flashed the supposed fix on the last page of said thread, but nothing changed, I still get the error.
Can anyone help me or advise me on what I need to do in order to fix this? I'm running 2.2 with the latest OTA and rooted. I've tried wiping everything also.
Thanks. Also, thanks to the mod who responded to my reporting of that thread and locked it.

[Q] Wifi Problems: Wifi won't turn on

Hello everybody,
I have currently installed the ev_bravo-nightly-2014.01.22-squished.zip on my desire.
But I have a problem using Wifi connection. I have read several threads about similar topics, but could not find a solution. I experienced the same problems with the previous release. At first, after installation, wifi worked well, but after having it turned off it won't turn on anymore. It also says MAC-Adress is unavailable. What I have done was to delete the app2sd script from init.d and to install Int2ExtV2 (runs perfectly). I don't know if this can cause the interference? I have not made any other changes.
Does anybody have an idea?
It would be great if anybody could help me.
I've had this issue with some Roms previously, the Wifi turns On, but won't turn on again after you turn it off
(is that the problem you're having?)
the solution/work around was to put the phone on Airplane mode, and back
this sometimes fixed it
..if not then I'd just restart the phone
there might/should be some other solution..look around or wait for someone to reply :good:
I can confirm that 'MildWild (Android 2.3)' does Not have this issue

Did you find a resolution to this problem? Mine has just stopped working after many years of being OK.
Cheers
I resolved this by running a factore reset eventually, but this of course means you have to reset up your phone from scratch.

[Q] [H] Wifi is greyed out and not turning on.

Hi! I purchased an m8 from someone else.
He also seems to have gotten the phone from someone as well.
He had a rom which I did not know, and I wiped it because he had personal data.
After coming home and trying to flash a new rom, the wifi is the only thing that is not working.
The wifi is not turning on. No problem with the router.
I tiried so many things. I got s-off by paying 25 dollars but still does not work
I got a boot.mg file but I don't think I have it for the rom that I am using.
I flashed so many roms but still the wifi is the only thing that is not working
The previous owner said the wifi was fine. What can do I?
If I understand correctly, you have a phone with S-Off and only a wifi issue. This sounds like a firmware issue.
You could try installing TWRP and then restoring an older Stock nandroid backup from here. Then update your firmware. I'm sorry I can't help you with the details since I am pretty new to all this myself.
As mentioned, you need to update your firmware.
