I also have an Intel Corporation Centrino Ultimate-N 6300 card in my laptop. I tried everything, but no solution. Kernel 3.0 worked while I have the problem since 3.1. Today I noticed something important: All the problems only appear with encrypted wifi. I noticed that, because I came across a free hot spot, and there it worked perfectly! If I am at home I can access to my WPA2 encrypted wifi, but I can't access to any webpage, which means I have no access to internet. This problems seems to be an encryption problem. (WPA for sure, I haven't tested any WEP wifi). All "solutions" I tried didn't work. I'm talking about kernels offered by archlinux. I tried orneiric on the live-cd version and there everything worked. Ubuntu 12.04 doesn't work.
