Server and bt voyager 2091

[smallsoldier]

Ok heres one to get ur teeth into before i bugger everything up lol. Have just moved house where i had lovely NTL 10mb connected to a server 2003 machine (via ethernet) and 4 machines which connected to the server - server has dhcp, nat etc

Ok now i cant get NTL i had to go with BT option 4 (highest one) and now have a BT router 2091 (with wireless) - how do i configure this so it works with my server ( i used to remote into the server from other pc's) i think this is easy - but, how can i do it so that wireless clients use the dhcp on the server and not the router itself !!!

Currently i have been plugging the router into the server and all works ok but for remote assistance etc i have to plug into the router directly to get it to work. Cheers for anyones ideas - u will laugh but i am an mcse and run my own pc business but i cant get into my head what i need to do lol
