I have a currently working home network with an Airport Extreme N Base Station, an Airport Express (n) configured for WDS, and several Macintosh and Windows computers either hardwired to the Base Station or connected wirelessly to either the Base Station or the Express. I also have two HR20-100’s located near the Airport Express. Both HR20’s are now hardwired to the Airport Express through a Linksys Ethernet Hub (model NH1005) (uplink port to the Express and two of the four other ports connected to the upper Ethernet ports on the HR20’s.) Unfortunately, I have not been able to get a network connection with the HR20’s, either by using the Default Settings or by manually setting the HR20’s to use IP addresses in the range 10.0.1.xx and using either the Base Station address (10.0.1.1) or the address of the Express (10.0.1.3) as the Gateway address. My searches here have returned mostly information on how to set up WDS (mine is already working) or how to set up non-Apple wireless adapters. I have rebooted all parts of the system several times, but still no connection. Any suggestions?
