I have 3 PC's connected with a wired router, I'm trying to connect a wireless laptop to the internet. I bought a Edimax USB netword adaper from OCUK and connected it to one of the PC's, I thought I could just use the internet sharing thingy like I could in Windows XP, I'm now using Windows 7 on all computers and havent got a clue how to set this up. Could anyone help me with this?
