Description of problem:

I have a Lenovo X200 with an Intel 5300 wifi chip. When talking on my WPA-secured network (Linksys WRT310N AP), it will work normally for an unpredictable amount of time (a few seconds to a few hours), then get "stuck", such that network traffic fails and existing connections get dropped.

Unfortunately, there's not much info in /var/log/messages to make it very clear what's going on. I'm happy to provide diagnostic info. Also, there is not an obvious event that precipitates the problem: sometimes it happens after a few seconds, other times after hours, with no clear correlation to network activity.

When this hang happens, I can usually kick things into working for another while by running "rmmod iwlagn && modprobe iwlagn", but the laptop will crash after a few of these forced unload/reload cycles.
