Hey guys,

So this is my problem. In my house everyone uses windows except myself and my friend. Since day one our Macbooks refuse to share our home wireless network; if my airport is turned on, hers doesn't work and vice versa.

I installed 10.6 yesterday and she is running 10.5.6 but the problem has been happening since before I had Snow Leopard. (I was quite happy using my Wireless Broadband until Snow Leopard said no)

I've tried searching everywhere for an answer and this is my last step before ringing Apple Care. My housemates are getting quite fed up with the network always dropping out when one of us connects.
