Hi folks, I have a bit of a problem. Without doing any updates (unless there was an automatic one that I can't remember), the wifi on my brand-new Thinkpad x220 has started dropping the connection every 10 minutes or so, and ESPECIALLY if I let it go to sleep. Pages don't load, and I can't access the router via the browser. In fact, I can't even ping the router.
The network manager in gnome thinks it's still connected, so I can't just hit reconnect. But turning the wifi off and then back on, or using the hardware switch to power-cycle the radio restores connectivity for a while, but it inevitably drops again.
At first I thought it was a network congestion issue, but changing wifi channels hasn't helped, and the issue doesn't occur on my girlfriend's laptop, nor on either of our phones. Additionally, I booted into Windows 7 on the same machine and have not experienced the same problem. So, I'm ruling out traffic congestion on 2.4GHz.
I'm running F16 with Gnome 3, with intel 6205 (centrino) wireless card. Running kernel 3.4.4
Nothing in dmesg, this is seriously puzzling. Please help!

Bump, edited original post after updating to kernel 3.4.4

Tried changing encryption modes on advice from #fedora folks, but no dice.
