How much would a wireless adapter cost, like , from gamestop or some store? I'm Thinking about getting one. And how can I use it, do i have to have a wireless network in my house or something?

My gamertag is Earth192

Check to see if you have a wireless enabled reuter , if you do , then buy an adapter , it should cost around $30-40

Brand new at a retail store they go for $99.99 lol. Gamestop also rips you off greatly. Doubt you'll find it for under $80 at a GS. IF anywhere look on amazon.com or ebay. You can find one for around $60.

You need to have a wireless network in your house or one close enough to connect to as long as you know its WEP/WPA or it's unsecure.
