Tiger doesn't want to airport


Got two new laptops with 10.4.2 on them. The wireless connection is light grey. I put their mac addresses into the airport and click on update. About 30 seconds later it says update was successful.

But when I go to connect to the network on them I get an error telling me they haven't been added to the ACLs on the airport. I go back into the airport admin and the entries are there.

I know there are airport troubleshooting docs on apple site but I don't think they fit this.

We did have a power surge a couple of weeks ago. I reset the airport and everything works ok for the other laptops. Help much appreciated - stumped on where to start with this one.
