I am configuring a wireless network, moving towards putting my ADSL router onto a Wireless Access Point. When my router is connected via Ethernet I can access the Access Point, but when I unplug my router (causing a "Network Cable Unplugged" status on the Ethernet port) I can no longer access the Access Point. When I attempt to ping it, the ping command hangs and does not return. Ping also hangs when I attempt to ping 127.0.0.1. As soon as I plug in the Ethernet connection, I can again ping to both the Access Point and 127.0.0.1. I suspect that ping is possibly trying to go off to the Ethernet network, but I can't see anything strange in the routing table. I have DHCP servers configured on both the ADSL router (subnet 192.168.1.x) and the Access Point (subnet 192.168.0.x) and each adapter is configured to use DHCP.
