Nighthawk with xfinity and 100mb connection issue

Question

As per the subject, I'm running the Nighthawk modem with xfinity. Normally I'm connected to my pfSense firewall with 2500Base-T. Last couple of days the internet has been acting up and when I go into pfSense I see it as 100Base-T. I have to stop the interface and restart it to get 2500Base-T back.

I also have ATT fiber on another port and it stays at 1000Base-T without issue.

This is something new that started about a week ago.

I'm wondering if anyone else has observed this behavior. It typically happens at night.

I don't know if it's xfinity playing with the router with their managed firmware or if it's something hardware-related (not ruling out firewall either).

What equipment are we talking about here?
&nbsp;
Which Netgear modem?
&nbsp;
If xfinity is the ISP, did it supply hardware of any sort that you are using?

Looks like a complicated setup. Is that a second Internet sevruce connecting tio the same network?
