Unbrick Tenda W1801R router












0














I have been running Tomato v132 on my Tenda W1801R router and few days ago, I decided to update to the latest firmware.



After flashed with v140, it worked fine for a few days. Then all of a sudden, the router doesn't assign IP and not broadcasting the SSID anymore. Tried 30/30/30 hard reset with no success.



I tried to connect to it via a network cable and setup the desktop to use static IP, couldn't get an IP either.



Tried to upload the old firmware with TFTP, but the client couldn't get a connection. So, is it really done?

  • Open the case, and look for a three- or four-pin header that might be a serial console. (The circuit board might only have solder pads, and not have the header installed.) Get a FTDI or similar USB-to-3.3v_TTL_serial adapter to connect to this header.

  • @sawdust you are right, there is no header to plug in a FTDI cable. So this router is done.
