The only laptop we have my wife uses for work and school so that's not an option. Thanks for the suggestion though.
If I can't find one locally this weekend then I will buy one on here.
Thank you for all the info guys.
Edit 3/20: My wife decided to get me the Wireless N Adapter as a late birthday gift last night so I'm back on Xbox Live.
