Okay, I tried the steps I proposed and now everyone is connected to the Valet but I can't find the NAS. I left it in DHCP mode and don't know what IP the Valet assigned it. I'm assuming it has to be in the range 192.168.1.xxx, but the D-Link Easy Search utility can't find it. My PC was assigned 192.168.1.118, so I guessed the router was handing out addresses starting at 1.100 and pinged 100 and 101.
How can I find my NAS so I can log into it and move it back to Static IP mode, and well, actually use it?
