I dont think the modem's functionality has changed. I feel it has something to do with the settings on Rogers' server, maybe something like the IP setup like OP mentioned.
Yes I did a factory reset to the MyQ gateway. It is directly connected to the modem.
Everything was working fine before June 21, 2020; and the myq gateway stopped working starting that day, showing no internet connection. The only changes on the day is the renewal of my Rogers contract.
When my contract got renewed, did Rogers have to terminate my existing connection and set it up again as a brand new connection? If that's the case, any chances that the new set-up is different from the previous one?

After switching to Ignite my previously working MyQ devices have stopped working through the MyQ app. Had to remove and redo all the set up to get them to work in HomeKit again - doors open and close with HomeKit so there is something very specific with the MyQ app and Ignite modem that is the problem.
