At a client's tonight. A few months ago I setup their network at their new house consisting of a Time Capsule and a hard-wired Airport Express to extend the range. They had a lightning strike and some equipment was replaced. The Airport Express wasn't working right. I did a full reset and reconfigured it. The Airport Utility complained that the WAN port was not connected. All the troubleshooting I did showed that the WAN port was bad. As I was about to give up I plugged the Ethernet cable from the switch downstairs into the LAN port - it worked! Previously I had that line coming from the switch going to the WAN port. There was a Blu-ray player hooked to the LAN port. So, I've lost the ability to have a second device connected, but it's working again as a network extender. Is that too weird or is it normal for the ports to get reassigned or repurposed?
