How do I factory reset my modem/router so I can reset the password to get into it?
What router/gateway do you have? See here for pictures/models. If it's the newer white Wifi 6E model(CGM4981) then you have to hold the WPS button for 60 seconds. If you don't do it for the full 60 seconds it only activates WPS mode. If that doesn't work, swap the router out for another one at the store. Seems that one wasn't refurbished correctly.
PS. A fellow Rhode Islander? Cheers!
Ahh, the black one. According to the support page, the reset button needs to be held 10 seconds for factory default.
On a separate point, may I ask why you are renting the gateway and not using the router part? Why not buy your own modem too? Do you get the gateway for free with your contract?
