how to use 3 wired airport express
I am trying to extend wireless to all my house. I have a router/firewall that will do all the routing. I have bought 3 airport expresses and wanted them to be hooked up to my network via ehternet for best performance. The first two work as described but when I plug the 3rd one in via ethernet, Airport Utility asks to extend the existing wireless network. But after a few minutes it brings down the entire network wired and wireless. But when I disconnect the ethernet cable from the 3rd one it works just fine. But of coures the performance is no were near as good with out the ethernet connection. Basically I am trying to eliminate deadspots in the house with there expresses but cannot get the 3rd one to connect via ehternet.
Thanks in advance
