Problem with connecting to my Netgear DGNB2100 wir

I just got this yesterday to improve my connection on my pc, xbox, bro's pc and xbox. We can get both the pcs connected fine but both the 360's wont connect, we have tried both wireless and both with the connections bridged though the computers, all of the settings are right but nothing. Does anyone else have this modem/router, or has some advice?

Thanks
