Xbox360 not accessing internet through wireless

[indie]

Hey was wondering if anyone can help. Im not sure if its my settings or if the routers is broken but i have 3 computers connected to the router. One is wired and 2 are wireless they all connect to the internet fine. However, i also have 2 xbox360s with the little adapters that can find the network but for some reason cannot connect. Although if i connect a cable in the back of them then they work just fine. I am confused and have followed all the intial help to this point...(unpluggin, DHCP turned on, manual configuration of the IP, etc...) nothing seems to work... Is there something im missing or does anyone have any suggestions?

Thanks in advance

is your network secure? If so are you certain you are using the correct pass code? It's a pretty simple setup so this should be easy to fix.

What router do you have?
