      I assume you also tried a different cable just in case? Since you can't get full speed connected directly to the ONT, I think you should call Verizon as something doesn't seem be configured properly on their end, or maybe there is an issue with your fiber signal level/quality, etc.

      I have been using Verizon FIOS gigabit service together w/pfSense for over two years and have always gotten full speeds - there is really nothing special you have to do to set it up (e.g. no VLAN's, priority tags, gateway bridging, MAC cloning, etc.) besides maybe a bit of network hardware tuning for high speeds.

      Hope this helps.

        Worth checking if your WAN connection linked at 1Gb full duplex. Check the Status > Interfaces page for errors.

          Given he's seeing 800-800 Mb in one direction, the interface is definitely running at 1 Gb. Also, Gb is always full duplex.

            Yup it should always be full duplex and it should always be autonegotiate. But we have seen equipment that doesn't stick to that. Though I agree it would have to be something more like a hardware issue to get such asymmetric speeds.

              Well I've taken another look at speeds directly to the ONT
              Started with a power reset of the ONT.
              Then with a new cable and laptop, verified I got 1 Gbps Full Duplex link up.
              Ran speed test through speedtest.net
              Got back PING ms
              7
              DOWNLOAD Mbps
              141.84
              UPLOAD Mbps
              242.88

              Then on verizon.com/speedtest
              DOWNLOAD
              405
              Mbps

              UPLOAD
              476
              Mbps

              both of these are terrible, and indicate something still ins't right hardware wise or provisioning?

              I guess I need to call Verizon now.

                Um, yeah that looks.... sub-optimal!

                Seems like an upstream issue.

                  Was that with the computer by itself? Or through pfSense? Try the computer connected directly, to see if the problem is with pfSense or the ISP. It's best to keep things simple while testing.

                    Yes the tests were with the laptop directly connected to the ONT with new cable and I got those results...

                      Then it's not a pfSense issue. Call your ISP.

                          Just curious what you guys think, but do you think Verizon has reason to dismiss a speed test done directly to their equipment? Dismissing your results, pointing blame at your device. Hence why I'm sure verizon's own speed test is the only one they officially recognize, as it separates "Device" and "Router" in its test. FYI, I don't expect to get 1000/1000, even 800/800 would be fine by me to device.

                            @lasermole - do you still have Verizon router/gateway? If yes, it might be worth plugging it in temporarily and run the Verizon speed test to the router. Given what you have described so far, I doubt that even that test will actually see full speed. If it doesn't, I expect them to help your further since the issue is then more clearly somewhere with their equipment.

                              Yes I do still have the router/gateway device. I could hook it up again and try through that to see what speeds I get. I'll let you know what comes of that test.

                                Tried the speed tests again with the Verizon router in place between the laptop and the ONT.

                                382
                                Mbps

                                "Router"

                                I really feel that "router" test is bull. I mean I don't pay Verizon each month to read how fast their devices are, to their network, on a screen...
                                That is not end user usable bandwidth. And I'm sure they will use that result to silence my complaints and shift the blame to me any way they see fit.

                                  @lasermole - do you have any other device (besides the laptop) you can test with? What are the specs of the device (laptop) you are testing with? Any third party firewall / AV etc. software running in the background which may be slowing things down?

                                    I've tested with two laptops, a Lenovo T520 i5 with 16GB of RAM, and 120GB SSD and onboard intel gigabit nic.
                                    And a Dell Precision 5530 with an i7 8850H 6 Core with hyper threading. Used a USB 3 Gigabit nic, as it doesn't have onboard.
                                    Both of which I went through thorough checking to kill anything running that would use CPU power, or bandwidth.
                                    The T520 had no firewall, or AV running during the test.
                                    The Dell has Carbon Black AV/Firewall on, its my work laptop.
                                    And each test the laptop was the only thing connected to the ONT, or the Verizon router.
                                    And to note I disabled the Wi-Fi on the laptops, and on the Verizon router from day 1. And I don't ever use the Verizon router. I only brought it in to test everything after i setup pfSense.

                                    Both laptops tested poorly in speed tests. as shown above.
                                    I have contacted Verzion, and will add another post with those results.

                                      So I got Verizon on the phone yesterday morning.
                                      I explained I was experiencing poor speeds on my Gigabit service.

                                      The tech immediately asked if I was using my own router, and explained they can't guarantee speeds to any device but theirs. I continue appeasing them and attach the Verizon router to the ONT, then my Dell laptop wired to the router directly, and we proceed to verizon.net/speedtest to do their speed test and get:

                                      Device (check)
                                      DOWNLOAD
                                      642
                                      Mbps

                                      UPLOAD
                                      767
                                      Mbps

                                      Router
                                      DOWNLOAD
                                      947
                                      Mbps

                                      UPLOAD
                                      911
                                      Mbps

                                      This still seemed kinda crappy, but I realized since they only care about the "router" speeds, and that absolves them of all wrongdoing with network on their side I accepted it and said "you can't help me any further thank you"

                                      Now I plugged my pfSense box back up as I normally have it direct to the ONT.
                                      And I did another speed test with the Dell laptop again...and mysteriously I got the best speed test I've got yet from Verizon's site with normal network hookup for me:

                                      Device (good)
                                      Download
                                      866

                                      Upload
                                      766

                                      So now I'm leaving things as they are. To note I do have pfsense WAN interface cloning the Verizon router MAC, but I already had that before. So I wonder if something just "clicked" into place now, or if Verizon changed anything silently? I made no new configuration changes to pfsense during this process.

                                        Would not be the first time a connection mysteriously started working after the ISP claimed to have found no fault. 🙄

                                          Funny now my speeds are crap on download again.
                                          And I'm sure nothing is eating all the bandwidth during my test.
                                          (tested through pfsense router )

                                          Is there anything that could "degrade" speeds over time in pfsense? anything that builds up or needs cleaning? buffers?

                                          Verizon speed test shows:

                                            @lasermole said in gigabit wan download speed much lower than upload:

                                            Is there anything that could "degrade" speeds over time in pfsense? anything that builds up or needs cleaning? buffers?

                                            Nope.
