Negate SOHO receving dhcp updates from ISP dhcp server & causing disconnects with internet

r0sebush a day agoHI,
I have a netgate SOHO router, with the lastest version of pfsense.
For the past few weeks, my sessions are getting disconnected, like my VPN into work and some games, website etc.I see in the system logs, when this may be occuring:
Sep 18 11:02:35 rc.gateway_alarm 3471 >>> Gateway alarm: WAN_DHCP (Addr:75.133.112.1 Alarm:1 RTT:7938ms RTTsd:1019ms Loss:22%)

Sep 18 11:03:39 check_reload_status Restarting OpenVPN tunnels/interfacesI have "chater" spectrum itnernet. it's a 60 mb/ 4mb up system. I have a cisco modem DPC3008.
Not sure why this is happening, but I saw a no too similar issue, where it was recommend to enable traffic shaping using PIRQ. So I set my speeds to 58Mb / 4 MB up. Seems to work, but there have been additional resets. Is this an issue with the PFSENSE and how it monitors the CISCO Modem? Do I need to disable the monitorings & actions?
Should I down grade b? Or do I need to understand from Spectrum why are they sending DHCP requests/refresh to my modem & thus causing the router to reload stuff. ** I've called them & they said they don't send frequent requests, but I don't think that they research this. So they're sending a new modem for me to test. ** IF there are issues, they will send another lines-man to test external lines again.
I had the cable line from the pole to house replaced. The tech found there was some kind of surge & it was causing timeouts on the line. Not sure if this is related to a much larger issue.
Any help would be appreciated. Thank you.

I've done a packet capture. It appears that the DHCP server is sending out a DHCP Offer. Not sure why the NETGATE is resetting some of my sessions/connections. Between the DHCP requests there are multiple ICMP PiNGs to the modem.150122 1729.155768 75.133.112.1 255.255.255.255 DHCP 351 DHCP Offer - Transaction ID 0x5e6ff866
150135 1731.173643 75.133.112.1 255.255.255.255 DHCP 351 DHCP ACK - Transaction ID 0x5e6ff866Any clues? Why is the netgate resetting sessions/connections??
Help? -
Pfsense doesn't just reset its connection on a offer ;) Nor would dhcpd send out offer unless it saw a discover or request.
My guess is your wan is being saturated, you loose your monitor to your gateway - and you have pfsense set to reset everything when that happens.
If your wan becomes full just turn off restarting states on loss of gateway.

@johnpoz I've set the monitor of gateway to NOT action on actions, but it appears that something is happening, extreme lag is occurring on my connection:
