I dont have my Xbox and i just purchased the wireless xbox 360 adapter. i bought it throu ebay. is there any way i can find out if it works through online?.

Get a new internal adapter

if ur xbox has the wireless adapter it doest need to be plugged in. if you dont have that adapter, you must either buy it and connect wirelessly or purchase a cable long enough to reach the router downstairs

it would not work as the console is designed to work with a special type of adapter that detects wireless network. besides most dongle internet network require you to install some sort of dial-up program on your system to connect before it can be linked up with the internet and this is not possible on the xbox 360.
you can purchase any of the compatible adapters from ebay.com or from the website if you prefer.
hope this helped you? please comment if you need more info.

xbox 360 wireless adapters are usally the worst to get.
i suggest buying a long enough ethernet cord and using that, a 50m ethernet cord is around about $25. so pretty cheap.

if you plug the computer into the usb port a box will come up and you register it as for the adapter get the one for the xbox plug it in and go to the dashboard then console setting then xbox live connection then test connection and if it doesnt work try the linksys one or the wired one.

the wireless 360 controller wont work because you have to get the adapter to use a CORDED controller for your computer.

go to amazon.com look at theyre adapters for the xbox they say it works for $45.00

The XBOX 360 can only be connected via an RJ-45 ethernet wire to the router unless you purchase the wireless adapter. The adapter can be bought at any accessory store such as walmart, Target, Gamestop, etc.

Turn off the console. Take out the adapter and plug it into the ports on the front of the xbox 360. if this doesnt work, you will need a new on.e

It only works with the microsoft adapter nothing else. You'll have to buy the Xbox 360 Wireless Network Adapter from microsoft and it cost around $100 bucks. It suxks that microsoft charge for this thing, it should come free with the machine
