Hi.
After 2 years uptime it disconnected from wifi and was unable to reconnect even after reboot.
I suspect my AC adapter has degraded. Can this SBC measure the voltage?
Upd: saw this post: https://raspberrypi.stackexchange.com/questions/112122/wifi-not-connecting-depending-on-power-supply
I use NetworkManager and when it starts it usually cannot connect to wifi saying that the pre-shared key is wrong, marking the connection as failed and not re-trying. In particular, the log contained a failed "asking for new key" message.
Re-starting the service or manually activating the connection worked.
As a workaround I created a *.conf file in /etc/NetworkManager/conf.d/ :
[main]
autoconnect-retries-default=0
Not sure if it helped though. One boot had a different error and a re-try. The other boot suddenly connected with the 1st attempt.
