My wireless connection cuts itself occasionally

[splashpot]

Every once in a while, my wireless connection will just disconnect for about 5 seconds, then reconnect. This happens about once every 10-15 mins. I am right next to the access point so it's not a signal strength issue. Both my mom and my brother use laptops in the house and they don't have this problem. And they sit farther away than I do. Is there some setting I can change or look at that might fix this problem?
