FYI, Innacomm W3400V is a free ADSL Modem + WiFi Router from Streamyx.
This modem + router have been branded by TM, so it have its own log
in page. The funniest thing is the log in page is do some JavaScript to
check whether the username and password specified contain any special
characters, such as !@#$%^&*. So, that means you cannot use any
special character on your password. But, if you try open the
configuration page and change your password using special character, it
will accept it.
The problem starts here. I have changed the admin user password on my
router using special characters. So, every time I tried to log in, it
always says the password is wrong, authentication failed, and so on.
So, I tried to find a workaround to change the password back, without go through the log in page.
1. Open
PuTTY
. PuTTY is a Windows based SSH / Telnet client and it quiet useful, if
you do not have it, you can Google it and download it for FREE!.
2. SSH to your router, enter your router IP address, normally it should be 192.168.1.1.
3. Once you connected, it will prompt you for username, just type in
the username that you want to change the password e.g. tmadmin
4. Then, it will prompt again for password, enter the password.
5. If you have successfully authenticated, the Main Menu will appear.
6. Type
passwd <option> <new_password> e.g.
passwd admin password then enter.
7. There are 3 options for
passwd command, which are admin, user, and support. Normally the username for admin is
tmadmin, for user is
tmuser, and I don’t know the username for support.
8. After that save the configuration by type in
save and enter.
9. Reboot your router, either reboot it by turn it off and turn it on again or type in
reboot.
10. Open your browser and open router’s web config. Log in with new password.
VOILA! You have changed the password!
