I'm going to throw out the facts that I have in case any of this ties it together for anyone...
This could be related to ongoing problems that I've been having with our business class service. Upgraded to faster service in December. They put in a new docsis 3.1 gateway and now have "securityedge" and the cradlepoint connection pro... honestly I don't want/need either of those... just wanted faster internet speeds for our customers.
New service was blocking all sorts of websites, set security to minimum and it still blocked sites that we weren't expecting (like a college student that wanted to turn in a paper through a college online portal).
Anyone able to connect these dots? I'm inclined to get my own modem but they said I can't with a static ip (which I would abandon to get more stable all around internet).
I've tried opening all ports on the comcast router too... credit card terminal still not working...
Sorry for the info dump above.
Thanks so much for taking the time to reach out through our business forums. It sounds like you have had a lot going on and the facts most certainly help and I would love to look further into the connection issues that you have been having. I am so sorry that you have experienced so much in such a short amount of time since this modem has been replaced. Can you please reach out through private message with your first and last name, full service address and account number or phone number?
