Purchased a netgear wireless card for my laptop and a netgear wireless router yesterday but had problems picking up a signal? We have cable internet so I ran a DSL cable from the cable modem to the router, but I'm wondering which port I am supposed to plug into, 1thru 4 or the LAN connection? I thought I tried everything but still couldn't seem to pick-up a wireless signal on our desktop. Have the card installed in the back of the computer w/the antenna screwed in. Any help??
