      @Gertjan thanks for the quick reply.

      According to the MAC, the manufacturer of the NIC is Realtek. It is a USB Ethernet adapter that is connected to the pfsense device. I have tested the ethernet adapter and cable, they work on other devices.

        @Bruzzler said in LAN Interface no carrier:

        the NIC is Realtek

        Copy exact these 4 words into Google ( www.google.com ), hit Enter, and read the first page for links.
        If you get really uncomfortable, don't worry, that's normal.

        Not sure ?
        Use youtube, and do the same thing. Now things will go downhill fast.

        The story always ends well.
        It start with : get an 'Intel' NIC ..... ๐Ÿ˜Š


        What about swapping WAN and LAN ?
        In this case the 'Realtek' won't be talking to the "TP_link Archer C50" anymore, but the Fritsbox.

        No "help me" PM's please. Use the forum, the community will thank you.
        Edit : and where are the logs ??

          @Gertjan Hey,

          I have changed the interfaces, now I can only access via ssh. It looks like I have to get another NIC like you said. Does the NIC have to be connected to the PCI or is it ok if I get an Intel NIC with usb connection?

            Realtek NICs are bad. USB NICs are bad. USB Realtek NICs.... ๐Ÿ˜‰

            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?

                      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.
