Router change password

@XfinityKassie​ Hello, I went on to the app and went into the wifi and then toggled on the tools. (Xfinity app → tap WiFi → tap your network → Advanced Settings → look for "Admin Tool Online Access" or similar → turn it on. )

Then tried logging in to 10.0.0.1 on safari and when it finally showed the page with the user name and password i put in what I was told in the chat which would be
admin   /    password as the credentials and it did not work. Told me incorrect information

Then I tried a second time logging in to 10.0.0.1 on safari and used the information that the same chat person sent me to print out for instructions and that told me to use

admin  /  the password on the bottom of the router. So I did and that did not work either.

Neither user / passwords provided by Comcast worked. Please assist

Hello, @user_kinim0 thank you for the additional information that is helpful. So the default username and password would be the one that is on the Xfinity gateway, that would be correct. It would only work if you hadn't previously changed that information, so if you updated that the only way the default password/username would be recognized is if the device has a factory reset performed. 

- Did you previously change the network username or password?
- Have you recently done a factory reset of the equipment, and the default information isn't working?
