I'm using a WPA2 EAP network. I'm sitting next to the access point. The connection keeps dropping and taking ~10 seconds to reconnect. My other devices are staying online. What's causing it?

syslog:

right after you got disconnected can you open up a terminal and run: dmesg | tail and post the result here? – binary.koala Feb 14 '11 at 3:47
@binary.koala Nothing significant there. – A Student at a University Feb 14 '11 at 3:47
I never figured out the problem, but I had this and it's fixed in Ubuntu 11.04. – zookalicious Aug 24 '11 at 1:47
