      Realtek NICs are bad. USB NICs are bad. USB Realtek NICs.... 😉

      But not always. What is logged in pfSense when it disconnects? What's logged in the access point? Is it connected directly?

        @stephenw10 I have the pfsense in the Fujitsu Futro S720 ThinClient, which has a NIC. Would it make sense to install a second NIC via the PCIe slot on this device? Is this even worthwhile for this device?

          What CPU does it have?

          But, yes, add another NIC if you can.

              Is it worth it?

                @Bruzzler said in LAN Interface no carrier:

                GX-217GA

                Mmm, well that's pretty old but probably fine for basic use as long as your available WAN bandwidth isn't above, say, 600Mbps.

                  I have a 100 mbps . I got a cheap USB ethernet from Dell. The problem is that I can't install another NIC or the cost is not worth it for the device. I have tested with the new adapter, but have the same problem, then I set both WAN and LAN interface to half duplex. It worked for 20 minutes. But I noticed that after I used more data with the client, the LAN interface switched off again. The internal NIC is also a Realtek.

                  It works, but not for long. My impression is that there is a data collision. I even had the case that both interfaces switched off. I am at a loss at the moment. I will try only the two usb ethernet as NIC and see how it works.

                    Half-duplex is pretty much always wrong. If you need to set anything fixed it would be at 100M Full Duplex. But you shouldn't need to.

                    I would use VLANs with a VLAN capable switch rather than USB Ethernet given the choice.

                    Try switching the NIC assignments. I assume the USB NIC is LAN currently? Make sure it's still the USB NIC that fails when it's the WAN.

                      @stephenw10 Until now, WAN has always been my internal NIC.

                        Ok, so try swapping it to LAN and see if the problem follows the USB NIC.

                        It may not. You might find it 'just works' as the WAN.
