C7000 AC 1900

[EricEin]

Had to factory default my C7000.  Typed in the 192.168 address to get into configure.  It takes me immediately into changing password for admin,  Set a new password, answer security questions, add in SN it says password changed .  Click on link to take me to set up and it takes me immediately back to password reset screen.  Defaulted modem several times, cleared cache in my laptop several times.  How do I get out of this endless cycle of terror?

make sure you meet the minimum requirements for the password. 

I use 

1. upper case letter

2. lower case letter

3. special character

4. number

5. at least 10 characters.  (might not need 10 but that's what I use)
