Flint 2 Router taking a very long time to connect to internet

Hi, I had my Flint 2 router working and then had some issues on the internet side of things that made my modem not work. Comcast came out and fixed that and now my modem works, but my Flint 2 won’t connect.

I hook it up and it just continues to flash light blue. I log into the activation page and under Ethernet 1 it says “Connecting…”. It’s been like this for 30 minutes.

I have a spare Netgear router that works perfectly fine when connected to the modem instead of the Flint 2, so I’m not sure what is going on.
