Help needed with Airport and 10.3, please.

Hi
I've been using my iMac (Airport Extreme card installed) as a software base station to provide wireless internet access to my wife on her iBook (Airport card installed). My iMac is connected to the internet through a DSL modem which is configured as the DHCP server. We have both been running 10.2, and there has been no problem.

Last night I upgraded the iMac to 10.3 and my wife can nolonger access the internet over Airport. The airport network is available and the iBook can access the network no problem, but the iBook can not connect to the internet.

I checked the network status on the iMac and it shows a green light for "built in ethernet", but an orange light for "Airport" saying that airport does not have an IP address and cannot access the internet.

The iMac can access the internet no problem, and I have checked and double-checked that the Internet Sharing is turned on.

Is this a compatibility issue with the DSL modem or something I can fix by configuring Airport properly.

Thoughts anyone?
Cheers.

 

Apple has been most helpful

As well as posting my Airport problem on a couple of forums, I emailed Apple to tell them about the troubles I was having.

Apple has been great, running their own tests and getting back to me with a solution the very same day. They confirm that there is an issue when a Mac running 10.3 shares its internet connection over Airport (as a software base station) to a 10.2 client. The Apple US engineers are now working on sorting this out. In the meantime they recommend upgrading the client computer to 10.3.

This is what I did and the problem for me at least was resolved.

At some point I will get myself an Airport Extreme base station, maybe I'll get myself one for Christmas;-)
