[SOLVED] FreedomBox disappeared from network list in router

[sunil]

I had a problem where my FreedomBox disappears from the router each time the network is disconnected and reconnected.

Whenever there is a power outage of a few minutes (which might happen like once in a week at my place), the router is switched off but the Pioneer edition FreedomBox keeps running on battery power. Once the power comes back on, I found that the FreedomBox does not acquire an IP address from the router. A reboot of the FreedomBox device seems to fix this problem temporarily. I also tried rebooting the router but that has no effect.

I connected a monitor and keyboard to the FreedomBox device and found that the device eth0 has no carrier. I tried restarting the services networking and NetworkManager but that did not fix the problem.

If the problem is repeatable by turning off and on the router, please check dmesg/journalctl message if eth0: link up/down messages. If these message don’t appear as expected, it would explain why the connection was not brought up after the router started again.

I checked if it’s a broken upgrade by running sudo apt -f install . The package installation of freedombox 19.14~bpo10+1 was broken. I fixed it by running sudo dpkg --configure -a as prompted and rebooted the machine. I think the problem is solved for now.

freedombox package in an inconsistent state can not explain why NetworkManager did not do its duties. Apart from configuring the connections initially, freedombox package has no role in how network connections are brought up or managed.
