      @stephenw10 icg1 & icg2. Yeah, it could be what are the chances they are both problematic and both drop at the same exact time?

          @stephenw10 different ISP, different modem make, and different tech (adsl vs fiber)

            Hmm, very unlikely then. So neither NIC ever loses link. The PPPoE sessions do not get disconnected. The PPPoE connections simply stop passing traffic.

            Do you see it logging missing LCP echos in the ppp log when this happens? It has to drop 5 before the ppp link is restarted and that doesn't appear to be happening but if the NICs stop passing traffic it would drop some LCP packets.

            Do you have access to the modems on a private IP at all? You could assign the parent interfaces with those IPs as gateway and they would then be monitored separately to the PPP link.

              No. In 10 days of PPP logs, I only see a single "LCP: no reply to 1 echo request"

              Do you have access to the modems on a private IP at all

              no. One modem doesn't have a web interface afaik, and the other is being used in bridge mode (so the router doesnt do any tcp/ip stuff with it, as I understand)

                Hmm, and the ppp sessions remain up on both WANs?

                And I assume you saw multiple WAN alarms during that time?

                    Importantly that? ^ The uptime on both WANs shows they never disconnected?

                    If that's the case this looks like something completely different. Like maybe it lost routing. Or something hung whilst reloading the filter maybe. I would expect to see something logged in either case though.

                      @stephenw10 thank you so much for your help! I'm nearing the end of my rope with these disconnects (as are my Zoom colleagues), and I think I'll just try a new box. Thanks so much!!

                        Hi sorry for asking for this to be simplified but apparently virgin media has broken there 2.5gig port with the latest firmware for the hub5 the thread on the forums say it is due to eee and would like to test this but so far can’t find out how to get info if it is enabled or not, am using an intel x710 card

                        Currently on pfsense 23.09-1

                        Can someone list the commands needed to get info about that state of eee my card is listed as ixl0 and ixl1, 0 is the wan port

                        Thread for virgin media https://community.virginmedia.com/t5/Tech-Chatter/Hub-5-Firmware-Upgrade/td-p/5480079/page/2

                          On ixl it is set by:

                          [24.03-BETA][admin@7100.stevew.lan]/root: sysctl -d dev.ixl.0.eee.enable
                          dev.ixl.0.eee.enable: Enable Energy Efficient Ethernet (EEE)
                          [24.03-BETA][admin@7100.stevew.lan]/root: sysctl dev.ixl.0.eee.enable
                          dev.ixl.0.eee.enable: 0
                          

                          You can also check to see if it's sending or receiving LPI symbols:

                          [24.03-BETA][admin@7100.stevew.lan]/root: sysctl dev.ixl.0.eee
                          dev.ixl.0.eee.rx_lpi_count: 0
                          dev.ixl.0.eee.tx_lpi_count: 0
                          dev.ixl.0.eee.rx_lpi_status: 0
                          dev.ixl.0.eee.tx_lpi_status: 0
                          dev.ixl.0.eee.enable: 0

                            thanks for that

                            would i be correct in saying that eee is enabled?

                            sysctl dev.ixl.0.eee
                            dev.ixl.0.eee.rx_lpi_count: 1205843
                            dev.ixl.0.eee.tx_lpi_count: 1448892
                            dev.ixl.0.eee.rx_lpi_status: 1
                            dev.ixl.0.eee.tx_lpi_status: 1
                            dev.ixl.0.eee.enable: 1

                              Yes that's enabled and it's both seeing and ending LPI.

                                  okay so managed to disable it but doesn't seem to be persistant through a reboot, but turning it off does solve the virgin media problem, just need to make it permament now

                                  to disable it i had to use sysctl dev.ixl.0.eee.enable:0

                                  and adding dev.ixl.0.eee.enable as a system tunable and a value of 0 survives a reboot :)

                                    I think if you look at my 1st post in this thread I mention adding an option to the system tunables section in the pfSense UI so that the EEE option can configured/persisted. I think that's still a thing?

                                    However, I thought @stephenw10 mentioned there was a bug (not sure it's fixed) that the EEE config below actually uses 1 to disable it, not 0. Although, this is for igc adapters, I'm not sure about your ixl adapter. Maybe @stephenw10 can chime in on how to use the system tunable for your adapter?

                                    @stephenw10 said in How To Disable/Enable Energy Efficient Ethernet (EEE)?:

                                    EEE is disabled by default in igc in FreeBSD. The description text for 'hw.igc.eee_setting' is incorrect. That should be 1 to disable it as mentioned.

                                    To check your current EEE configuration:

                                    [23.05.1-RELEASE][user@router.lan]/: sysctl hw.igc | grep eee
                                    hw.igc.eee_setting: 1
                                    [23.05.1-RELEASE][user@router.lan]/: sysctl dev.igc.0 | grep eee
                                    dev.igc.0.eee_control: 1

                                      I see you found the system tunable! I guess I'm wondering if using a 0 actually disables it. Again, there was mention of a bug in this thread that system tunable uses a 1 to set EEE to disable (at least for my igc adapter).

                                        That's true but that only applies to igc.

                                          How I’ve configured it works for my case and card and is easily tested as with it enabled I have 90% packet loss and with it disabled it works and zero loss

                                          Thanks for all the help and to @stephenw10
