Wireless Adaptor Help

[Jam]

I just got my Elite back from Xbox but now my Wireless Adaptor will not connect. My Xbox finds the Adaptor but not my network. The router is literally just below the Xbox, so it isn't range. I've never had any problems before I sent it off, but when I tried it on my mates Xbox when he came round with it during the time it was broke, it didn't work then. I am connected by ethernet ATM, but I've payed £60 so its wireless, so I'd prefer it to be wireless.

Help?

I don't know if any possibily but send your wireless back and use ethernet, OR send your wireless adapter back to get changed if still in warranty.
