After a system reset my DIR-615 E1 insisted on a firmware upgrade. I did so, same FW I used early this year, and now I see the globe light and all four Ethernet ports lit, no WiFi light, and the thing is unresponsive to my browser at 192.168.0.1, where it had been before.
Repeated resets and power cycles have had no affect.
Did I just brick my poor WiFi router?
