I do not know my user ID - Computers & Internet

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.
