Hi there, A weird one I need help with. We have 3 macs at home and an iPhone that have all been joining my airport network with no problems since day one. A few days ago my girlfriend's Macbook just stopped seeing our network on her machine. All are now running 10.5 and were fine as they were with 10.4 My MBP and iMac are fine. Nothing has been changed on the MB and it still sees out neighbors networks and works ok anywhere else. Can anyone shed any light on this as I am baffled. I've tried everything I can think of and it just won't see that one base station at all. I've just done a complete erase and install of Leopard and it's still not seeing the base station. Thanks in advance.
