Wireless Access DSL Sharing – HELP

I have Orinico RG1100 wireless network receiver connected to NIC and DSL to another NIC. Have PC card. All I want is to share DSL. Everything connects fine, good signal etc, except I can do nothing to access DSL from portable. Messed with a Linksys system for two months and paid consultant before trashing it, now one more try. I have tried everything I can think of. Running XP pro both computers. I bet the answer is easy, but finding someone who hasit hasn’t been. THANKS IN ADVANCE. Ed
