It sounds as though a process dies due to some command which gets sent and
cannot be interpreted properly by the driver. My guess would be that you
need to re-run the process to resolve the issue until the next crash. Have a
look at the log files to see what is happening and be aware of the culprit.

What happens if you set up your addresses statically? Maybe communication
with the DHCP server triggers an issue. Try to set up your DNS servers
manually. Maybe they get de-allocated or re-assigned, depending on the
nature of the network you are connecting to.

They tend to preserve the last known configuration, I think. Even if the
connection is not there, the fields will not remain void based on what I
know from Windows.

I was going to say "Make it CTRL+ALT+F7, just to ensure you don't get
'jammed'". I never knew that just ALT was enough to return to tty7.

Excellent point, clearly made. There are lists on-line which indicate which
hardware is Linux-friendly. There is no good excuse.
