wierd d-link problems

Ok, I have a d-link 2xr wireless router connected to the basic rr (roadrunner) modem. I have both a d-link dwl520 and a airlink mimo adapter (not running at the same time). I couldnt get the signal range needed from my router, so I bought a d-link g repeater. The repeater picks up the router and I think connects to it, and my card will connect to the repeater. I have 93% connectivity to the repeater, but the internet is not flowing through the repeater, it's not transmitting 'net to the adapter...Any thoughts would be much appreciated. Thanks
