Unstable internet connection - dpinger issue?

[pseudonym3k]

Currently on 26.1.1 but this started on 25.7.

OPNsense ran without issue for nearly two years, then after the upgrade to 25.7 we started having connection dropouts.

During a period of connection instability, the below is repeated several times in the gateway monitoring logs:

Warning dpinger exiting on signal 15
Notice  dpinger MONITOR: WAN_GW (Addr: xxx.xxx.xxx.xxx Alarm: down -> none RTT: 20.0 ms RTTd: 1.2 ms Loss: 0.0 %)
Warning dpinger send_interval 1000ms loss_interval 4000ms time_period 60000ms report_interval 0ms data_len 1 alert_interval 1000ms latency_alarm 0ms loss_alarm 0% alarm_hold 10000ms dest_addr xxx.xxx.xxx.xxx bind_addr xxx.xxx.xxx.xxx identifier "WAN_GW "

I have tried so many IPs, from geographically close server IPs to Cloudflare and Google DNS IPs. None have worked, though some have caused more dpinger exits than others.

Several days ago I ran these tests:

1. Configured a nearby IP known to have near 100% uptime and fast response, in gateway monitoring. With my phone on cellular only (disabled wifi radio, disabled bluetooth), I ran continuous pings on that server for several hours.

2. Changed my phone to ping my own public IP for several hours.


No pings failed, but our internet connection still dropped periodically, and the dpinger entries were in the logs.


I disabled gateway monitoring after the above tests and we haven't had any more connection drops AFAIK.

I am just a home user and my OPNsense has very few minor tweaks over the default install. And while I don't strictly need dpinger - I have no backup connection - I like having a record of internet disruption especially when I've been away.

Is there anything else I can do/look at, to troubleshoot and (hopefully) get dpinger working well again?

Thank you for any help and info.

Kind regards.

This might not be your problem, but I've found that some providers, particularly wireless providers, sometimes drop the abnormally small ping packets sent by dpinger. For all of my gateways I set "Data Length" to 56 (you'll need to switch on "Advanced Mode" to see this option).

I have cable (Spectrum), nonetheless it's worth a try. Thank you! 😊

I am also having this issue. 
Sometimes the gateway comes back but I had a situation today where it dropped about midnight and was still down at 5am even though i could ping the monitor address from Opnsense. 
This has only started to become a problem since 26.1 - was fine on 25.7.11_4.   Editing and applying nothing on the gateway config gets it going again.
