Re: Does the Pi 3 have a quality problem with onboard wifi?

My suspicion is a driver issue, since we have quite a few reports in github with the same symptoms that I am fairly sure are either driver or firmware problems, not HW. Thanks for the feedback, Jamesh. Could you tell me what files I should be looking at to verify that it is a driver or a firmware p...

Re: Does the Pi 3 have a quality problem with onboard wifi?

The HW is pretty simple, so unless your specific device has an issue, I doubt there is quality issue with the Pi3 design itself. I'm not questioning the design , just what I've got in front of me, namely a new Pi 3 whose wifi didn't work from the start a Pi 3 which worked perfectly for 7 months unt...

Here's the github thread which may be your problem https://github.com/raspberrypi/linux/issues/1342 from that there's the following possible workarounds: change router wifi channel from 11 to 6 ensure country is set correctly in /etc/wpa_supplicant.conf ( connecting from a Samsung phone kills wifi ...

Re: Does the Pi 3 have a quality problem with onboard wifi?

This is not a HW problem, it's a driver issue. This is encouraging. However, it does not match my experience. The board failed when I did my cron-driven weekly reboot. I hadn't changed any software. Also, when I booted the defective Pi with the USB stick that worked with another Pi, `wlan0` was sti...

BT is switched off because the EnOcean board uses the serial interface.

I'll start one of the duff boards up later and see what's in dmesg.

Re: Does the Pi 3 have a quality problem with onboard wifi?

@elkberry I don't think it's anything to do with the access points: only the Pi 3s are having problems, not any other devices.

When I do

Code: Select all

ifconfig -a
only `lo` and `eth0` show up (no `wlan0`). Also

Code: Select all

sudo iwlist wlan0 scan
fails with a message to the effect that it doesn't support scanning.

Does the Pi 3 have a quality problem with onboard wifi?

I have three Pi 3s running Jessie 8 (jessie-lite from March 2017, I think). They are equipped with EnOcean Pi boards and have been running 24x7 since November 2016. Recently, one lost its wifi connection and I couldn't get it back. I ordered a replacement from Digitec here in Zurich, but wifi didn't...
