how can i extend my network using an airport express
I have an airport express that connects wirelessly to an airport extreme. I would like to use it to extend my network. It has a strong signal coming in to it from my extreme. It works fine when I try to connect to the network, but it dies completely when I try to use it to extend my network. After going through a restart, it disappears from the network. The only way to bring it back to life is to unplug it, let it rest a few seconds, plut it in again, and then reset it to Connect to the Network before it crashes again.
I have a model of the express that is supposed to work with extending the network.
Thanks for any suggestions.
