I installed the kubuntu-desktop package on a normal Ubuntu install, but beforehand set up a TimeShift snapshot in case I wanted to undo the install. I logged into kubuntu but it was unable to connect to the internet. After restoring the TimeShift snapshot, I still was unable to connect---neither on my elementary OS dual boot nor on a liveUSB session.

It always seems to fail on "getting IP configuration." Here are the results of some commands:

$ ifconfig -a

I solved it. The problem was not my computer but rather the router (just did a restart). The router wasn't able to allocate new IP addresses, so eventually every device on the network would have been affected but my computer was the first.
