Hi,
I've just joined this forum for help with my WR941ND router. I'm totally stuck! FYI I'm not a hacker.....
I tried to upgrade the firmware of my WR941ND because of a problem I had with internet connection dying (something to do with wireless router not working properly with my ADSL modem? Seems like DNS stops working because I could ping an IP address, but not via its URL.
It happened after 5 to 10 minutes of surfing.
Anyway I used the Web GUI and a file from the TP-LINK site and attempted to upgrade the firmware, however, at completion, my browser did not refresh!!!! Oh oh.....
After searching, I discovered this thing called openWrt and this forum. I found posts about accessing a serial debug port.
So I grafted an RS232 interface onto the four pin header of my WR941, and shorted R356.
(After somewhat munting the fricken case to get it off!!!)
Below is what I get if I power the unit up. Is there anyway I can return it to stock or have I inadvertently BRICKED my wireless router??
I thank you in advance for answering a clueless noobs questions.
Best Regards, Nick
