If you’re reading this, it’s probably too late. You’re probably already running into this issue:
and it’s probably driving you nuts!
If you haven’t done the move yet, good. Telnet into the router and run:
nvram get http_username
and
nvram get http_passwd
The way that Tomato and DD-WRT store passwords usernames and passwords is different – DD-WRT stores them encrypted whereas Tomato doesn’t, so with this, you can use it to log into Tomato after you’ve done the move. I call it a move and would hate to call it an upgrade, because some hardcore DD-WRT users might be offended.
Now, if you haven’t done this already and are seeing the error, this will be interesting. With the ASUS router, I think I was able to just do a 30-30-30 reset and it took care of it. Unfortunately with Shibby’s implementation of Tomato, they don’t implement the reset button, so you can press the reset button until you’re blue in the face and it won’t do a thing. On other routers, you may need to press the SES/AOSS button. On the Netgear Nighthawk, it’s the WIFI on/off button. You can hold it down and it will start a password-less telnet daemon at port 233 if held for 20+ seconds. So, when you’re booted into Tomato (the web login will still say DD-WRT) and you can’t log in, hold the button down for 20+ seconds and then go to the command prompt and run:
telnet <router IP> 223
There, you should be able to run the 2 ‘nvram get’ commands and use that info to log into the router and do a reset from there.
Hope this helps!
