Failing Raspberry Pi 3 config; WLAN disappears

Hello! First post. New to snaps.

I’m going through the RPI3 Getting Started and after I “Press enter to configure” and after I set up my Wi-Fi access point and click “Done”, it begins “Applying network config”, stops at 66%, apparently loses wlan0 (it disappears from the screen), and reports “brcmf_cfg80211_reg_notifier: not a ISO3166 code”.

The access point is running a fairly recent DD-WRT and it’s been working well for Macs, iOS, Android, and various media devices.

I’m trying to connect it to a 2.4GHz mixed mode AP on channel 6. (I set it to channel 6 after some Googling on this problem suggested that might help. No joy.)

I also saw some comments concerning possible under-powering of the RPI3, but I’m using the same set-up I have otherwise, and I did also grab a second USB power block to try that, too.

Any thoughts?

I did find some references to disabling power management as a possible fix. I’m open to that, but was really trying to go straight demo and keep it simple.

Looks like you are hitting bug or (i guess we should merge them)

Using a wired network during setup, rebooting, then ssh’ing into the board and runnig “sudo console-conf” to set up the wlan woks fine btw. This is only broken on the first setup screen, wifi is rock solid beyond this.

Thanks very much! I added my info above to that bug report. Now I just have to get an HDMI screen in the same room as I have Ethernet. :slight_smile:

Just an update to confirm that trying wired and then running sudo console-conf did indeed work perfectly. Thanks!

This is actually fixed with netplan 0.23~16.04.1

…which is in the core snap in the edge channel (so all daily image builds already have it)

(actually turned out to be Bug 1696162)

Cool… I’ll probably get a chance to test this out soon as I’m hoping to try and work on this project I’ve had on my mind for a while.
