I am facing same problem. Router was working fine with v2.07NA. On 13 January 2013, after flashing firmware v2.10NA, Router seem to have bricked. Unable to do recovery using firmware upgrade system page (http://192.168.0.1). Status bar shows waiting for http://192.168.0.1/cgi/index.... Nothing happens further.
When tried flashing with firmwares 2.07NA, OR 2.10NA it shows error as "Incorrect Hardware ID Image"
This message does not appear for versions older than 2.07NA.
Even tried router setup software of Dlink. It gives an error that Ethernet is unplugged, even if plugged in. (tried several working ethernet cables).
Tried calling local Dlink office in Dubai. No one picks the call. Very frustrating and dissapointed.
