Networking after Buster upgrade

Sat Jun 29, 2019 9:24 pm

I upgrade a Pi 3B to buster successfully, but after a reboot wlan0 is not connected.

In checking the properties, I'm offers a long list of options none of which seem appropriate. MY network uses WPA2 PSK AES, which of the many options in Wicd is appropriate?

Cheers

Thanks!

When I use rasps-config, the networking option reports 'Could not communicate with wpa_supplicant.'

For anyone with a similar problem that needs ACTUAL help, it turns out that rfkill was somehow set on the wlan.

I unset it and all is well.

Please explain how one tells if rfkill is on and how it is turned off. Thankyou.

I suspect the quickest solution would be to follow the currently recommended path by using a fresh buster image download and installing any supported systems needed for your application.

@cflyer185 I discovered the issue by digging on DuckDuckGo. I issued the command 'rfkill list all' and I could see all interfaces. After digging a bit more there is a switch in the guy wireless setup that I had missed.

@PhatPhill, I agree if you don't have an extant system, or you're happy to rebuild everything. Not my situation :-)

Cheers
