I just got cable modem. The computer upstairs works fine when hooked up directly to the modem. I have another computer i would like to receive wireless internet too downstairs. I have a wireless G D-Link adapter for that computer and a wireless D-Link router for the upstairs. The problem is that I can not get either computer to run internet whenever I hook up the wireless router. I hooked up the cable from modem to WAN spot. The computer is hooked up to the 1 spot on the router. If anyone has any ideas on what I need to do PLEASE Help!! Thanks
