I have a problem in my OpenWRT router when I try to upgrade my router

(TP-Link TL-WDR-3600) to openwrt firmware via web ui. Now my router is bricked and I can't connect

the router via WebUI (, putty and WinSCP. I checked the ipconfig command in

command prompt. But the Default gateway is missing.

Finally I try to connect via USB to serial cable using putty.

enter image description here enter image description here

But the putty is shown a blank screen for a long time. ( 30 minutes ).

I am really hopeless, I think my router is seriously crashed.

Could you please suggest any advice?

    How have you hooked up the serial port to the router? Can you try a speed of 9,600bps - 115,200 may be too fast.

Do not panic. I do not think that your router is bricked. It is just unreachable for you PC. Did you try to set the IP address of your PC manually to Your PC now has This address cannot communicate to your router.

  • How did you try to connect to your router? WIFI or network cable? Should be by network cable and with an IP address that is in the same subnet as
