Hi everybody,
any suggestion on how to make a Cable modem talk to my Airport express? 
It was all working fine until a few days ago when it all went dead.
I can connect the Macbook to internet if I plug in the ethernet cable but when I try to connect through the airport it doesn't work.
Telstra Clear says they don't support home networks (this must be new, I've been using the airport express for years with no problems until now!!!) so I can't get help from them.
I thought maybe the shaking in Christchurch had damaged it, so I had the Airport express checked by the Apple service centre but they said it works fine.
I set up the ethernet connection with the settings given me by Telstra Clear (IPV4 manually, IPV6 automatically, no proxies).
Thanks  heaps for your help!
