I've attempted to switch from my wired network to a WiFi on with Internet connectivity (to check for updates), and this opened a can of worms.
In the Network Manager, I unchecked "Use Default Wired Profile" at the top, which was probably a mistake.
Then with my WiFi connection seemingly working, I was no longer able to establish a Remote Desktop connection (to the static IP configured for the WiFi network). So, I restarted the Id. However, then it started failing at the network setup stage: it would not connect to either the wired network, nor to the WiFi, and stop the boot process without opening JRiver.
In the attempt to fix the problem, I did things, which did not help me:
1) A full reset ("Restore Defaults" - option 77)
2) Restored the BIOS settings defaults (hope it did not break anything).
I was eventually able to get it back to a working state by manually re-configuring the wired connection.
But the very next time I switched to my WiFi network with Internet (this time without the static IP or the setting to "always join this network"), I got myself back into the same state: not being able establish the wired connection, upon restarting.
Fiddling with the configuration of the wired connection (mainly, just opening it in the text mode, saving, and manually re-connecting), I'm back to "normal" again. However, I feel the network connectivity is no longer stable, and the problem may recur any time. (Also, FYI, starting the Id in the GUI mode without a successful network connection causes additional problems: JRiver crushes immediately upon start up, and there are other errors).
What should I do? Should I just send the unit to you, for a complete re-imaging? Are there any other ways to get the Networking stable? Is it possible that restoring the BIOS defaults caused any problems?
Sorry for the long email. But, arguably, the fact of attempting to connect to WiFi should get the ID to the state, wherein it's unable to even properly boot.
