We've opened up 1 of the laptops and there appears to be three antenna cables. 1 black, 1 white, and 1 grey. The grey one wasn't attached. Any one know what these different antennas are for? We tried unconnecting the white antenna cable and connecting the grey and it seems to be a bit more stable (at school, yet to try offsite).

Weird, we have a whole bunch of these cards in our machines that seem to go fine, hp 6730 s with Vista though so they may come properly connected out of the box.
The three antenna wires are for three seporate antennas, due to wireless N the MIMO (multi input multi output) approach uses differing signals from each antenna to get the cleanest signal possible by also grabbing reflected signals and also allowing for better control of the returning signal. Basiclly the N draft standard uses all three antennas and the card allows G to benifit from this as well.
I have seen this kind of thing before with alienware laptops which strangely had rubbich wireless signal. Opened them up only to find one antenna not connected at all, connected it up again and it was fine. This incompetence was evident on multiple machines - alienware (at least just after being taken over by Dell) are junk. I would suggest connecting all of the antennas and giving it another go.
If you brought them recently with Vista Business licenses then you may have the 7 upgrade avalible soon which may allow you to use the possibly much better drivers avalible to later windows versions.
