Pixel 6a WIFI and bluetooth not working

bfge

Hi! I have some issues with the WIFI and the bluetooth on my pixel 6a .
A few minutes ago i finished flashing GrapheneOS and the WIFI and Bluetooth dont work (thing that was happening on the stock google android).
Should i try to do something or is this a software issue?

We haven't had reports of that. Can you give us some more information about exactly won't work? Does Wi-Fi not connect at all?

Can Bluetooth now find any devices?

matchboxbananasynergy They dont work at all, cant even scan for wifi networks. Also when i try to turn on bluetooth, it "tryes" and shuts down after a while.

Please try going to Settings > System > Reset Options > Reset Wi-Fi, mobile & Bluetooth and see if the issue persists.

matchboxbananasynergy Tried it again as i did on the stock OS, but no luck , it still does the same.

Now i wonder if its a hardware or software issue. In the april update on the stock os the WIFI stopped working and today bluetooth too, i was getting some crash copup messages but thats it. On the forums i see that also some peoples are facing issues with radio related stuff (on the stock os)

Considering that I haven't seen any reports relating to GrapheneOS releases or experienced anything like that on my end, I would also lean towards this being a hardware issue instead of a software one, unfortunately.

matchboxbananasynergy Thanks, ill try to debug the issue a bit more, and if it doesnt work, ill have to reflash and rma it

Am using a 6a on GOS. Not aware of any issues. Which build did you flash?

bfge There's a new build for me today. It's all working so far. TQ2A.230505.002.2023050100

pdagenius i think im gonna rma the phone, in the worst case scenario ill get my money back and get a pixel 7

Long time update: I sent the phone to the RMA and got the money for it, it seems that it was a hardware issue
