I am having some problems at a clients house with a home network going down and am having trouble diagnosing it. Let me give you the layout and see if you can offer any suggestions. There is a time capsule router connected to the Cablevision Modem. THere is an active ethernet port in the wall in the kitchen. I connected an ethernet cable from the wall jack to the WAN port of an Apple airport Extreme, and then from a LAN to the Imac computer. There is also an airport express that is joining the network. I have the Time capsule connecting via DHCP, and have the airport extreme on bridge setting. I have the SSID, password, encryption all the same, but channel different. The problem is the Imac is getting kicked off the network and it shows the strange WiFi signal with a straight line through it. At this point connection gets lost. Time Capsule still shows green light, but Extreme shows amber light. I did not open up Airport utility to see what it was saying. I am guessing it is either an incorrect set up or a faulty Apple Airport Extreme. I have now unplugged the extreme and am just using the Time capsule to see if that holds up for a few days. Any ideas would be appreciated.
