Backpower fried wlan0?

What is the problem?

I have an Ender 3 and a Pi 3. I haven't used it in a while, so I was logging in to update and get ready for a project, but the pi wasn't on the wifi network. I connected the ethernet and it grabbed an IP and I updated, but wlan0 will not connect to the wifi network. Is it possible the backpower problem fried the chi?

What did you already try to solve it?

I have confirmed the information supplicant.txt file - no change
I put the micro SD into a different Pi and it connected to the wifi, so I think I have a hardware problem.

Have you tried running in safe mode?


Did running in safe mode solve the problem?

Afaik the wifi chip is connected via usb so that's not impossible but I never heard of it.

I would connect the pi via ethernet and run a wifi scan to make sure it really doesn't work at all.

Ssh into the pi and run

sudo iwlist wlan0 scan
