I updated Ubuntu to 14.04 LTS and I can no longer see my network - No network devices available shows in the network drop down menu. Networking is enabled and if I choose to boot my Dell Inspiron 1300 from the network I do see some activity on the card but none in Linux. Both lights on the nic stay on permanently.
I don't know where to look for the equivalent of event viewer or similar to even start to troubleshoot, having only about two hours with the install before I updated. Original install was last October.
Any pointers on where to look in logs etc would be gratefully received.
