Wifi does not work

[Josar]

Try to get an new RPI3 to connect to a wifi network but this does not work.

Error listed from dmesg | grep brcmfmac :

I updgrade to the last kernel which runs fine on an second RPI3.

Maybe its an faulty device?
Or where can this come from brcmfmac: brcmf_sdio_bus_rxctl: resumed on timeout ?
Thanks in advance.

I have not seen errors like that before, especially so consistently. If the same image runs on a different Pi3 with the same power supply then I have to think it is a (very rare) hardware fault.

That's what I see and WiFi stopped working here too after firmware upgrade on RPi3; the OS is ArchLinuxARM here.

Had a capacitor soldered instead of an resistor. See pictures.

Bad device with a white capacitor instead the usually black resistors. (Sorry for the bad quality.)

Working device.

Repaired device with 22 Ohm [0402] resistor instead the 22.5 Ohm [0201].
Worked instantly after boot.

Wow - that's amazing detective work. If you send the serial number of the faulty board and a shipping address to [email protected] I'll make sure you get a replacement.

@Josar That is really amazing !

As a new rpi user the pi zero w works perfectly but the rpi3 exhibited the same errors so I've been racking my head for a couple of days, trying different kernels and firmware I've given up....

However on inspection it seems that my wifi was shipped chipped :( Hugely disappointed as this is going to hold up dev

I'm sure this is the cause of my woes

I seem to be having this same issue. I have no wifi interface on one Pi 3 but I can switch the SD card to another Pi 3 and it works perfectly. When hovering over networking in the top bar it says: wlan0: Not associated.

I am getting the same error as mentioned above. My Raspberry Pi 3 Model B Rev 1.2 is old and I was not using it for a while. The USB WiFi works, eth0 is there but internal wifi is not working. This occurred one more time a while ago but WiFi started to work automatically again. Now, it's again not working and I have searched a lot. None of the solutions work.

Thanks so much. I've tried to track this down a few times in the past, but just had to use hardwired network. I did not find a capacitor, but i did find that that resistor was broken and mesured 3 MOhms. I replaced with a 20 Ohm and at least wpa_supplicant will connect. I still need to check my configuration. Bluetooth also started working and connected to a keyboard. At least I know that it was a hardware problem.
