My DWR-921 rev c3 router has stopped working after I attempted upgrading the firmware. Resetting the device doesn't work. And browsing to 192.168.0.1 says "This site cannot be reached".
I have tried to do the emergency flashing described here: http://forums.dlink.com/index.php?topic=44909.msg163599#msg163599. When the router comes on, all the led lights on the front panel flash continuously with the exception of the power indicator. I have tried the same procedures on a different computer with the same result. I'm at my wits end. Any help will be appreciated.
