Raspberry Pi 3 WiFi not working

,
1

Hello guys! I downloaded raspbian for robots and the wifi DID NOT WORK with my raspberry pi 3 model b v1.2. I was tearing my hair out thinking I had a hardware problem and actually ordered a new raspberry pi, and was aout to return it. Wlan0 was not working, nothing was connected, no online help was working… then thought I might as well try vanilla rasbpian or something first. The wifi works fine on vanilla raspbian.

Hi @ajavdk,

One thing here on that particular image (if you still have it of course):
What does ifconfig -a show up?

And what does it mean that it doesn’t work?
Does an error show up when connecting to an AP or does it not do anything at all? Or is it that the WiFi menu can’t be accessed?

Thank you!

Hi there - only Lo and Eth0 show up IIRC, not wlan0. On vanilla raspbian (jessie) wifi connects fine. The wifi menu can be accessed but does not get a signal from WPA supplicant IIRC.

Hi @ajavdk,

I have an idea: does running

sudo apt-get update && sudo apt-get install firmware-brcm80211

solve your issue?

Thank you!
