Through this morning the networking functioned normally. Then I noticed a
batch of new system updates. After installing and rebooting the trouble
returned, slightly worse. Now the internal wifi simply fails to connect.
The external usb-wifi adapter works as expected. I'm again seeing failures
reported for networkmanager-wait-online, but don't understand what they mean.
Looking through journalctl output, filtered for wlan0, I see a torrent of
output, some of which states:
Nov 30 09:19:00 raspberrypi NetworkManager[852]: [1732987140.7820]
device (wlan0): Activation: (wifi) association took too long
Nov 30 09:19:00 raspberrypi NetworkManager[852]: [1732987140.7821]
device (wlan0): state change: config -> failed (reason 'no-secrets',
sys-iface-state: 'managed')
Nov 30 09:19:00 raspberrypi NetworkManager[852]: [1732987140.7826]
device (wlan0): Activation: failed for connection 'Wi-Fi connection 1'
Nov 30 09:19:00 raspberrypi NetworkManager[852]: [1732987140.7828]
device (wlan0): state change: failed -> disconnected (reason 'none',
sys-iface-state: 'managed')
The mismash of reasons looks inconsistent to me.
The only changes have been disconnecting and reconnecting the usb-wifi
dongle, right now it's connected and the gpio is showing 5.08 volts. I
suspect the small fluctuations seen reflect line voltage drift more
than load.
In any case, I've now navigated successfully from the frying pan back
to the fire 8-)
Thanks for reading,
