Intermittent WAN, lose WAN DHCP IP address

opticalc

pf sense loaded on a zbox C-series CI323. been running great for months, but now all of a sudden multiple times a day it just stops working. when i check the dashboard theres no longer an IP address on the WAN (dhcp/ethernet to a cablemodem)

Ive noticed that going to pfsense and disabling then reenabling WAN will fix it, also powercycling the cable modem fixes it as well. Is there some setting I need to make to catch this happening so that it is automatically resolved?

Is you ISP doing a cut every xyz ours or per day?

opticalc

not that i can tell.

I think this is some kind of malfunction with my WAN's DHCP client system. the last log I have is from a number of days ago.

and on bootup, syslogd reports:

syslogd: /var/log/dhcpd.log: operation not supported by device

im not sure what device it refers to, possibly my pfsense is just not renewing my lease? I dont believe im out of space:
