All the Internet TVs I've seen in the UK come with their own wireless dongle which plugs into one of the built-in USB ports. If yours does not have one, buy one from your local computer store - probably around £15 UK or $10 US - plug it in and run the Setup utility in the TV's menu. You'll need to know the wireless security key to allow access to your router and the guide to finding that is here http://www.tomshardware.co.uk/forum/38111-18-find-change-wireless-security
