Update to the last D-Link firmware through web-ui before OpenWRT
installation then follow the instructions to patch your device using
D-Link FailsafeUI.
- D-Link FailsafeUI:
Power down the router, press and hold the reset button, then
re-plug it. Keep the reset button pressed until the internet LED stops
flashing, then jack into any lan port and manually assign a static IP
address in 192.168.0.0/24 other than 192.168.0.1 (e.g. 192.168.0.2)
and go to http://192.168.0.1
