New Router/Notebook loses wireless connection every 5 mins...

[dogsballs]

I just set up a new cable modem and wireless router, linked to my cable internet service. Wireless router is D-Link DI-624.

One notebook works fine with the wireless, but the 2nd notebook (the one I play poker on) works fine with the wireless only for about 5 mins, before losing the connection. Then it claims it doesn't find any wireless networks within range. But if I go to the Networks Connections control panel and hit Repair, it goes through the repair process and everythings fine for another few mins, when it happens again.

I set the router up on the 1st notebook. The 2nd notebook never previously had any problems connecting wireless. The signal is strong when it's going.

Any ideas what's causing this? Anyone had something similar?


Thanks for any tips.
