I have a Belkin pre-N wireless router (F5D8230-4) hooked into my cable modem upstairs, which of course feeds the wireless signal to my house. I want to have my old Linksys BEFW11S4 wireless router connected to my xbox 360 downstairs as a wireless "adapter". Is this possible? If so, how? In case you haven't guessed, I don't want to spend $100 for the xbox wireless adapter, or have to run 100+ ft of Cat5 to the across the house.
