The other day, I installed some updates (in 12.10) and rebooted after I was prompted. I then found that I could connect to the router, but no websites would load. After several reboots and connecting/disconnecting from the network, I noticed my assigned ip never changed. Thinking that maybe the dhcp lease wasn't properly being renewed, I ran dhclient in the terminal.
Since today I'm not able to load webpages on my pc. This happened after I resumed the suspended Windows.
I am connected to my Router via WLan (tried lan, lan via wlan client; no difference) and while all other computers in this household have proper working Internet, this PC in particular refuses to load webpages.
