Username password change on Balance 20x

I thought for security on my home wireless network I would change the default password for my router. I went to the IP address on the label on the bottom, changed the username and password both previously admin but when I tried to log back in I was unable. What did I do wrong and how do I fix it? Someone changed my Google password on me and so I’m worried about my network security.

Nevermind. There must have just been a “delay” before the new usernamed and password took effect.
