Wireless internet on laptop with built-in antenna?

Probably because the laptop detects the Link-Sys wireless box, but for some odd reason it wont connect to it, and it works well on the Desktop just like you mentioned...Does the Laptop have a built in Ethernet port? You can plug a blue network cable and plug it to the Link-Sys box, and you can try to connect it. But I prefer doing this wireless if its on a Laptop.
