I have wireless internet in my house I want to know how to get internet connections for my xbox 360 without any cords.
Without Cords and wireless network adapter

How much does the xbox 360 wireless network adapter cost. like in total, tax included because i only have 5 and was wondering if that was enough thanks.

I want to plug my 360 into my computer so i can use my computer’s wireless connection to get onto xbox live. If i can avoid buying a wireless network adapter for my 360, i will be very happy. My operating system is windows vista home basic.

I dont know if i should get a PS3 or an XBox 360. I want to get an xbox 360 and play xbox live but it costs for that and plus i dont have a computer near my TV so ill have to spend another 0 to get a wireless network adapter. That totals 0. The PS3 is 0. I do admit that Xbox 360 has better games but PS3 will get better games. Also itll cost me more to buy an xbox 360 than to just buy a PS3 ( which has free online and WIFI). Even if i do get the Xbox 360, is it worth paying 0 (0 for the adapter, 50 for the Xbox live Subscription) just to play Xbox live? Ive also heard that the wireless adapter breaks very quickly. Is this true? I do like the Xbox 360 better but i mean it breaks down a lot plus u have to pay for everything which is gonna total up to be alot more than the PS3. So should I get an Xbox 360 or just get the PS3?
I have a PS2 and a PSP right now.
