Reset Router Password To Default Settings

(Use this as a last Resort!)
Find Your Default Router Password
Simply select your router manufacturer from the list below to display the default router passwords and usernames.

Your Internet service provider (ISP) requires a username and password to access service features, including Internet and email.
Your ISP should provide this information when you set up your Internet service.
Typically, once you complete the setup and save the information, your router or modem transmits it behind the scenes when you try to access the Internet.
As a result, the username and password can be easily forgotten because they are not used daily. If you reset your router or simply forget the password, gaining access to network resources and the Internet becomes a challenge.

Navigate to your router's Internet Protocol (IP) address using a Web browser, entering the IP as if it were a Web page URL, to view its Web-based configuration page.
This IP address varies by network, but if you run a home network the IP is most likely 192.168.0.1.
Oftentimes there will be an "Account" section where you can view your user name and, if the router's firmware was written poorly, your password in plain text as well.
Look at the original documentation you were given by your ISP.
This documentation often includes your user name and password.
Also, if you use a combined telephone and Internet service, your user name and password are likely identical for both accounts.
Your user name and password may also be the same as your ISP email account.

Check your billing statements.
Some ISPs only require an email address and some personal information to authenticate.
Your billing statement will include additional information, such as your account number, that may be a part of your log in credentials.
Call your ISP and ask them to reset your password. Some ISPs may provide a Web resource for acquiring or resetting your password. Try your ISP's website before you call them.

Reset your router back to it's factory settings by holding the reset button for about 5 seconds. I have provided a list of the most popular router brands. If it does not work you may need to google what your specific model's default IP address/default username/default passwords are, for example search for "Encore ENHWI-2AN3 default IP address" The default login info can change, it can depend on where you obtained your router. If you purchased it yourself from a store then the standard defaults should work. If you obtained your router from your Internet Provider you may need to contact your service provider. It also may depend whether it's an old or new model router as well. And you may need to press and hold the reset button on your router several times before it actually clears. Make sure you have a wired connection then once you have accessed your router simply run the Setup Wizard. Set your SSID as something you'll remember like "Mavericks Network" and your Password can be something like your phone number for example 3109876543

The NIC card will need to be reset back to the factory defaults if you do not have the user name and password.

If you contact me through www.gfbm.net I will assist you with resetting the scanner over the phone.


Once reset the scanner NIC you will need to re input the IP and all your other scanner information.

I hope this is helpful,
