Wifi "Wrong password" error after update v.1.2.1

[LordOveride]

Running on Raspberry Pi5 , previously before update to v.1.2.1 , the wifi works fine. After update, it kept giving "Wrong password" even though it is the same password and been working previously.

What seem to be the problem ?

Hey @LordOveride,

Could you try running the following command on your umbrelOS terminal to reset all Wi-Fi connections on your Pi:

sudo nmcli -t -f UUID,TYPE connection show | grep wifi | cut -d: -f1 | xargs -I {} sudo nmcli connection delete {}

Warning

If you are using the web terminal, please make sure your Pi is connected to Ethernet so you don't lose connection. You will need to be on a wired network temporarily to set up Wi-Fi again on umbrelOS.

Following that, you should be able to set-up Wi-Fi using the http://umbrel.local/ settings app. You may need to reboot first though.

If you have any issues with the set-up, check to make sure the Wireless interface is up sudo ip link set <interface name> up, you can find out the name by running sudo ip a.

Explanation

As for why Wi-Fi wasn't working, I'm not too sure but my guess would be the key got corrupted somehow or something in the network manager configuration changed so it wasn't able to connect again.

For transparency purposes the command above will do the following things:

• sudo nmcli -t -f UUID,TYPE connection show lists all the network connections on your Pi.
• grep wifi will filter for Wi-Fi networks only.
• cut -d: -f1 extracts the UUID of the network to delete
• xargs -I {} transforms the parameters in a way nmcli can understand.
• sudo nmcli connection delete {} will delete the Wi-Fi network(s) effectively resetting the connection.

Hopefully these steps will help you get back online!
