Hi my name is ***** ***** I can assist. Try this method below, if you haven't already.
1. Plug the Ethernet cable that connects your computer, that was plugged into one of the LAN ports, 2. Setup your PC with static IP - ex: 192.168.0.2 (different from 192.168.0.1)3. Make sure the PC has the new firmware 4. Unplug the power5. Hold the reset button for 3~5 seconds and re plug the power WITHOUT RELEASING THE RESET BUTTON.6.Open a web browser to 192.168.0.1 and then you should see EMERGENCY FLASHING page then click browse/upload locate the file and click UPLOAD FIRMWARE NOW
What is the H/W Version on your router? It should be on the label.
Just checking with you again. Are you still in need of assistance?
