I messed up my wifi - Redmi K20 / Xiaomi Mi 9T Questions & Answers

I flashed a new rom and now the phone connects to my home wifi but fails to get an ip address.
I have tried other roms that worked in the past but no dice, the error reproduces every single time
I wiped data, formatted it, made a factory reset, flashed roms following the instructions but i havent been able to fix it.
Anyone can give me a hand with this?

Does the phone know its WiFi MAC address
If custom ROM affected your Persist, phone lost its MAC address and cannot connect to WiFi - you should restore your original Persist
But then you probably also lost certificate for DRM L1 (and AFAIK that cannot be restored)
Price for playing with some custom ROMs
Check about Persist in other threads here under Q/A and Guides, things were discussed couple of times (I dunno more, my Persist is still ok)

Thanks a bunch, mate. It shows wifi and Bluetooth mac address, so it looks like that is ok, unless im checking in the wrong place.

[READ]AOSP ROM broke my mobile data

I built latest ICS from AOSP. I also used the proprietary binaries. I immediately wanted to test wifi and mobile data and it didn't work...
So I flashed back to Pixel ROM. There my wifi worked again but mobile data connection not
Then I flashed latest KI radio. Still no mobile data...
My provider is Proximus
The APN settings seem correct at first glance.
#151# is showing me I have 179MB left
What can I do to fix? I tried numerous ROMs and radio's? Is it possible something is broke on my Nexus S?
IMEI 357194041841347
IMEI is still correct.
My device is showing no wifi mac adres or not bt adress. Also no ip adress. Maybe it is because wifi and bt are turned off...
Maybe I am paranoid, maybe not. Maybe I flashed a wrong partition ? I was hoping someone could help me.

which AOSP rom did you use ?
You might want to remove that IMEI number. The guy that quoted you also.

Flash latest factory image via fastboot which will completely wipe your phone, backup your important stuff to PC .

Wifi and Bluetooth isnt showing up any networks and MAC is 02:00:00:00

People do you even have a solution for my WiFi problem? I have been asking this on several forums but unfortunately I get no reply, my N6P is no more detecting WiFi signals and Bluetooth. I literally get only loading screen on my WiFi panel and end up loading at the end only. I flashed stock images as referred by one of my friend but unfortunately nothing happend N6P without a WiFi is boring guys please help.
I don't get Bluetooth signals also
There is also no IP address seen and it is showing unavailable and MAC address in 20:00:00:00 from long time
I have been done flashing stock firmware images of Oreo and Nougat.
One day long back it's been months, I once tried flashing custom kernel it suddenly worked then I don't know when it disappeared.
Anything related to kernel and the signals of WiFi and btooth ?
Your help will be appreciated guys help

If you have already wiped your phone completely by formatting the partitions and flashing the stock image using flash-all.bat script, there is nothing else to do. Both Wi-Fi and BT are on the Broadcom chip soldered on the motherboard. Try again. Ensure you have the latest ADB/Fastboot binaries on your PC. Connect your phone to the PC and fastboot format (not erase) system, userdata, cache partitions and then use the batch file included with the full image. This will return your phone to bone stock. If you still have the problem, the motherboard and/or chip is bad. If you have "already done that", you are at the end of the road.

Oneplus 5 does not connect to wifi networks

Hello!
My Oneplus 5 does not connect to any wifi networks. It is able to see all wifi networks in the range, and is also able to save the network if the password entered is correct, however, it won't actually connect to any network that is saved. I have tried using advanced options while connecting to a network to change from DHCP to Static settings, but it still won't connect to any network. I have also tried changing the wifi band frequencies (2.4 and 5 Ghz individually) to connect to a network but that too does not help. Mobile Data and carrier signal on the other hand work flawlessly, and so does bluetooth connectivity, NFC and personal hotspot (which is why I am very confused). I should also mention that when it fails to connect to a saved wifi network, it occassionally displays "Disabled" under the network SSID (replacing "Saved").
I have changed 3 different ROMs (LOS, stock OOS and No Limits ROM, even replaced the stock kernel with blu_spark r69 when I tried using No Limits and stock OOS to try and see if that fixed the problem), but the phone just won't connect to any detected/saved network using any of those ROMs. I have reverted it fully back to stock now (OOS 4.5.14 and stock kernel and stock recovery) and am still having the same problem.
Sorry if this issue has been solved before and if I am reposting something, but I really need this fixed ASAP and am not able to find a working solution after searching the forums and googling the whole day. Please help me! Thanks!
Edit: finally fixed the problem thanks to Ivints and PeterGuru. Check out the post that Ivints linked below (especially the comments in page 2 of the same)

Thank you so much Ivints! I'm trying to fix it right now with the solutions I got from the post.
I'm having exactly the same problem that the guy who started that post had. I'll let you know when I fix it and everything goes well again! Thanks again, bud!
if you want to stay on Nougat look for the O2N revert flash file it's in the Oxygen 5 beta threads that will let you get back to a nougat based rom.
The Oreo update touched other partitions outside of /system so those wifi drivers don't work with Nougat anymore

I see... I'll look for that thread and get the flash file! thanks! I'm currently using xXx's No Limits 9.2 OB03 ROM with bluspark 3.2.1 recovery and bluspark r77 (Oneplus 5). The only reason that I feel like reverting back to Nougat is that I want to be able to use Xposed again. So i guess I have that option in hand not too! Thanks, bud!
Hello there my friends, i have a problem with my op5
its about wifi: it doesn t see my wifi anymore. idk why
it s been connected to this wifi 2 years ,even after switching roms kernels, firmwares
and now , it doesnt see the wifi no more, actually it sees it, in `Saved` section, but when i press on it to connect
it says ` not in the area` but my other op6 its connected no problem
and i even tried through qr code, it says ` check ur connection and try again`
Just one add-on cause I was just a few minutes away from formatting my data. My OP5 unlocked rooted, rest stock, wasnt connecting to my home wifis (2,4ghz and 5ghz). I flashed a full ota zip. I deleted wifi bluetooth via backups settings.
But I found out that connecting to an iphone hotspot worked. So I entered manually the network SSID + password although the same network name was already in my wifi list (with marking: "saved"). I then clicked on the second "new" same wifi and it directly connected to my home wifi. Same happened to the 5ghz network. I then deleted the old 2 ones.
I have no idea why this happened, I only tried to get VoLTE/Wifi Call running with the magisk module. This might changed sth but I dont get the connection here since there should be no interference...

Oneplus 5 Wi-Fi problem

Hello, i need some help...
I've already searched and tried a lot of ways to fix my problem but nothing worked.
Suddenly the Wi-Fi of my Op5 stopped working, i cant even turn on... And also the phone doesn't recognize sim cards. The phone isn't rooted.
I've already made factory reset, flashed another rom, cleared cache, etc...
Thanks in advance.
Check if Your both sim's IMEI and WLAN MAC address are displayed correctly.
Sounds like corrupted EFS partition to me. Try to restore backup (if You have one). I think You can't fix this issue without a backup. So only way is to send it to OP for repair (i guess on warranty it should be free).
