The problem is the "also connected to the modem".
Xfinity only supports 1 public ip address (unless you pay for more or are on a business class line).
Meaning that only 1 device can be connected to the modem (even though it has more ports).
So disconnect everything from the modem, power it and the router off for 2 minutes.
Then boot the modem back up and give it a couple minutes to fully boot.
Then connect the router and boot it up.
Try setup that route.
