Are you talking about WD’s “My Net View”. That just does a simple arp -a, but doesn’t say anything about client signal levels or which are on wireless and which are wired.
If you’re talking about about another piece of software I’d appreciate a link.
have you made any progress on this? I am also running my new N750 in bridge/AP mode and want to see wireless client status. It seems that the WebGUI is severely limited in AP mode.
