N300 WiFi Range Extender - Won't Connect - Redirects to Login Page

Hello! I've searched and can't seem to find the answer to my particular issue.  I initially set this wifi extender up about a year ago with another internet service provider.  I am trying to set this up now with my account through Xfinity however it won't connect. 

I get through all the settings, all the way to Connect any Wifi enabled device message and this is where it stops every tme.  I check the box where it says "Click the continue button" (Sorry for the bad image, its from someone else video) and when I do it brings me back to the login screen for the mywifiext dot net site. I feel like i'm in groundhog day and i'm probably missing something very simple. 

When i set it up the first time about a year ago I never had any of these issues. It was a smooth setup process. I've done the factory reset a few times.  Not sure what else i'm missing and why it keeps rerouting me to login. 

Thanks!
