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, bob prohaska --- SoupGate-Win32 v1.05 * Origin: Agency HUB, Dunedin - New Zealand | Fido<>Usenet Gateway (3:770/3) .
