Airport 5.3.1 utility and the old base stations

Airport 5.3.1 utility has a bug. It has a hard time to see the old base stations g. Usually it just ignores them, making access and configuration of the base station impossible. If you make an initilisation of the base station, it just makes things more complicated since it resets it to the factory default and then it can not be regulated.
Since we lack confidence in the Apple updates, we have duplicated version 5.3 before the 5.3.1 update. We have put it on our servers after the reports of our readers, and await for Apple to find a solution.

Attention, it works with Leopard. We do not know if it works with Tiger.
