WAN status unknown

[moosport]

After I swapped out a combo cable modem for a standalone.  Pfsense 2.3.4 ran without issues after reboot.

After a few weeks, WAN0 is showing unknown status. It does not pull an IP anymore.
Broadband connection works when I plugged in a laptop directly to the cable modem.

I did not change the clone MAC which I had used forever.  Any ideas what maybe the cause and how to fix it?

ISP did not see an issue on its end.
