Hi, I recently upgraded to faster broadband only to find my desktop PC is not wireless. What can you recommend as far as upgrading it to be able to connect wirelessly? I have moved my modem from my office to the lounge and connected in there, leaving my desktop unconnected to the wifi network. Any advice would be much appreciated. I presume I need something like a "wifi adapter" but don't understand the difference between the antenna looking ones and the nice compact ones. They seem to range from $19 to over $100, and I am presuming you get what you pay for, but any advice and comments would be appreciated. Cheers!
