When I try to connect my brothers xbox 360 wireless'ly to internet I go through the motions but when it comes clicking the tab 'wireless settings', that tab isnt highlighted, and wont let me access it, so I cant get to it to scan for wireless networks available etc etc, how do I get past this? I have inserted the disc in case an update is needed and the system doesnt read the disc at all, which apparently means the software is up to to date? the router is (i think a netgear DG834GT) can anyone help?
