      Yup eee should be disabled.

      The values for hwpstate_intel should be set lower for higher performance. Setting it to 100 means the most power saving / lowest performance. Try setting it to 50 or just disable that. The default value depends on what the BIOS passes though.

        @stephenw10 as it is I just deleted it entirely, so it shouldn't be doing any limiting at all. I couldn't find any specific features in the BIOS pointing at this, though, so I'm just running on defaults now. Fully rebuilt PFSense and still having the same loss issues, though, but, as I've confirmed loss on a second router as well, I'm leaning back towards an issue with the provider instead...

          The hwpstate_intel driver is enabled by default and should select 50 by default. That should be more than sufficient but as I said some of those devices have some very odd choices set in the BIOS by default. You should try setting a high performance value there like 30 and see if it makes any difference.

            @stephenw10 I'll give 30 a go. The seeming irony to my situation is my RTTs to my gateway monitor IP aren't even bad, it's just I'm seeing enormous loss (on ICMP):

            If I run a throughput test I sometimes see 200-400Mbps down, which is in line with what I'd expect, but the issue is tunnels are dropping and apps disconnecting

              Check the mac stats shown in: sysctl dev.igc.0 or whichever NICs you are using.

                  Missed packets or errors. Check the other NICs in use. Also check the other sysctl values for errors.

                  Also check dev.igc.X.iflib.override_nrxqs. We had to set that 1 on the 4200 to prevent context switching issues.

                      Mmm, try setting those to 1. You may need to add them as loader values to /boot/loader.conf.local.

                        @stephenw10 yeah, no dice on that.

                        The only thing I will say is I tried a USB NIC and that also was seeing packet loss, so at this point I can't fathom, besides a CPU issue as a whole with the Topton box, how this could be anything but the provider's problem. Unfortunately they insist there's no connectivity issues to their modem and the gateway I'm connecting to is upstream of that, so theoretically they should see an issue if there was one...

                          No difference at all with a much lower hwpstate_intel setting?

                            @stephenw10 I blew away my router entirely and rebuilt it from scratch, restoring some of the FW side of things but not the system tunables and other settings just so I could confirm I was starting with a clean config. Here's what I have:

                            And here's what we look like:

                            ANd here's what the system log looks like for gateways:

                                  Can you just show the full output from sysctl dev.igc ?

                                      igc.0 is the WAN that is seeing the loss

                                        Just to add to the curiosity, all loss cleared up approximately 2 hours ago and appears to have remained stably loss-free since then. I spoke to my provider again and they seem quite insistent there is nothing wrong with my circuit and they see no reason why this should be happening. However, they also confirmed the modem they have given me is quite dumb and 1) cannot hard-code interface speeds/duplex and 2) does not support a DMZ host, so if I moved it back to router mode I'd need to manually open each and every port.

                                          @rmeskill said in High interrupts on WAN/LAN interfaces?:

                                          dev.igc.0.mac_stats.good_pkts_recvd: 147664355
                                          dev.igc.0.mac_stats.total_pkts_recvd: 147669598

                                          Hmm, the only thing I see there is that. Implying ~5000 bad packets received. But no errors so probably just rejected. Not really a huge number out of 147M.

                                          I see about the same percentages here:

                                          dev.igc.3.mac_stats.good_pkts_recvd: 1208385
dev.igc.3.mac_stats.total_pkts_recvd: 1208642

                                          And have no issues.

                                          One difference I do see is no msix_vector values:

                                          dev.igc.3.iflib.allocated_msix_vectors: 2
dev.igc.3.iflib.use_extra_msix_vectors: 0

                                          Do you see that in the boot logs?

                                            Oh and note that the igc driver can only link using negotiated speed and duplex. It will fail to connect to a NIC that is actually using a fixed speed and does not negotiate.
