Wireless Adapter wont connect to Internet!

hello,

i recently bought a couple belkin wireless G mimo adapters, and i cant get them to work with my network! for some reason, they only work with one of my computers. if its connected to any others, it just connects to the network, not the internet, and then gets stuck on identifying. its trying to connect to a wireless N linksys router, never had any kind of problem like this before, all of my other non belkin adapters work fine with the network, and the signal is 3 bars, so im at a loss here, any help?
