Dlink WBR2310 Connection Problems

I picked up one of these routers to use with my Macbook and it seems to disconnect every 15 minutes or so. I would have to turn Airport off and on to use my connection again, or have to reset the router itself. Is there anyone else that has had this issue with this router and could offer a solution? If not, I might just consider dumping this router and purchasing a better one.

try updating the firmware for it. If that does not work, just return it and get a different router, as that 1 could be faulty
