Sys-net Crashing - Help Needed

Qubes has been running well for a while, however an error is now occuring, which is causing my sys-net VM to crash. The crash occurs upon connecting to a network. I was able to connect to a network once, but sys-net crashed when connecting to sys-whonix. I’m using an external wifi adapter.

What commands can I run to see logs of the issue?
Any tips on how I can identify/solve this issue are appreciated.

You can find VM logs in Qube Manager. Right click on the VM and choose “Logs”.
