Okay the User Guide for my Wireless Router has this in the instructions and I'm sorta confused. "For initial access to the Router through a wireless connection, make sure the PCís wireless adapter has its SSID set to
linksys (the Routerís default setting), and its WEP encryption is disabled. After you have accessed the Router, you can change the Router and this PCís adapter settings to match the your usual network settings."
My questions is do all computers come with a wireless adapter or is this something extra I also have to buy? And which one do I install/setup on the PC first? The Adapter or the Router?
