My airport express has been acting VERY strangely lately. One moment everything's working, next moment I click a link and nothing, no sweet sweet internet going to my MBP. Just now it happened, and I tried using airtunes, again nothing. It said the airtunes speakers could not be found.

To fix it, I have to unplug the airport, plug it back in, let it reset then hook the modem back up to it. I've been having to do this five or six times a week lately, and it's a real pain. It always works just fine after I do that, but only for an unpredictably short time. Any guesses as to what's going wrong here?
