I have a linksys WAP11 wireless access point. I've had it for about a year.. Whenever I use it for 10 or 15 minutes, it kicks me off and removes from my available list. If I hard reset it, I get another 30-45 minutes and then have to do it again. Other times, after I reset it'll work for 2 or 3 days before having to be reset. Any thoughts on the cause of this?
