My Ubuntu 13.04 did some updates over the past few weeks (honestly, didn't pay attention... the pop ups said "updates available, do you want to install?" and I said "yes" without reading them). Before, I was able to connect to my home WIFI with no problems. I haven't used my Laptop on my home network for about a month or so, so I don't know exactly when the problem started, but now I cannot connect to my local AT&T UVerse gateway (2Wire) hub. The odd thing is that I have no problems connecting to every single other wifi network.
1) Yes, I've checked I have the correct WIFI passcode
2) No, I do not have MAC filtering enabled on my gateway
3) No, I do not have "limit the number of connections" enabled on my gateway
Sooo, WTF??? Please point me in the right direction.
