Help w/wireless adapter

i bought the wireless adapter and whenever i try 2 use it is reports back as "disconnected", the light is a steady red though which means it should be connected

sum1 told me it was my xbox so i sent it in 4 repairs, i just got it back and i'm still having the same exact problem any suggestions?

and the adapter isn't breaking because i used it on my neighbors 360

Buddy, that adapter is a piece of crap.

I had it, never worked.

I bought a 500 ft. ethernet cable, a few drill holes later I've racked up over 100,000 kills and have a 2.13 k/d ratio on CoD4. Get the long ethernet cable. :)

^actually mine works perfect. His is probably defective. There arnt many complaints about the wireless adapter.

but how much does the 500 ethernet cord cost?
