thanks for the advice and info guys. i will probably just pick up a wireless usb adapter, as this seems like the simplest and quickest solution. fyi, i do actually do a lot of online gaming and over the years my pc gaming has mainly been with laptops and on the move so using wireless has been the online option. probably also explains my misconception about pc's already being set up for wireless. meanwhile i have also gamed a lot on psn when at home, and have used this with wireless and wired connections to no noticeable difference..
is the main issue with wireless vs wired packet loss? and is the difference really that big? i do not use far from the router..
