      You need to determine what exactly is failing. Check Status > Services, is anything down?

      Check Status > Interfaces, is the LAN still UP?

      Check the system logs when this happens.

      You may be exhausting something. See:
      https://docs.netgate.com/pfsense/en/latest/hardware/tuning-and-troubleshooting-network-cards.html#intel-ix-4-cards

        @Jimbohello said in Urgent Lan Dropping:

        even static in my pc, no network

        If even static devices lose the network, it has nothing to do with pfSense. Perhaps a little more info would help.

        PfSense running on Qotom mini PC
        i5 CPU, 4 GB memory, 32 GB SSD & 4 Intel Gb Ethernet ports.
        UniFi AC-Lite access point

        I haven't lost my mind. It's around here...somewhere...

          Maybe switch need to be to autoselect like pfsense !!

          Or both on static setting like 10gbe full duplex?

          Hard to diagnostic when nothing as Failed on 1 gig lan for almost 5 years

          Switch lenovo ce0152tb campus

          Thankโ€™s ๐Ÿ˜€

            First off, always use autoconfig, unless you have some specific reason to not use it. However, do some testing. If you have 2 computers with static addresses, can you ping between them? If not, it's likely a switch issue, as pfSense is not used between devices on the same LAN. Even with DHCP, it should take some time for a failure to be noticeable, as devices retain their address, until the lease expires. Break the problem into byte size pieces, so that you can see what's failing. What you're doing is like calling up a mechanic and sayimg "My car doesn't work, what's wrong?"

                If the switch port is set to fixed speed/duplex then the pfSense end should also be.

                On some 10G/1G dual speed ports we do see it is sometimes necessary to set 1G fixed to get a link.

                None of that should fail after some time though, it would either link or not. Something like an mbuf exhaustion would usually prevent traffic on all interfaces.
                Checking the logs for clues would be my first step here.

                    The main System log in pfSense. I'd also check the switch log for link failure on the port.

                      Master crash today all network down .
                      So i find out that all packet on the lan where getting error in or out donโ€™t remember ! Like million of error

                      I put back my intel 1000 pro
                      And everything look fine

                      So i thinโ€™k 3 possibility is possible
                      Failed nic
                      Failed fiber
                      Failed transceiver

                      Iโ€™ll let you know in the future

                        told you ill get back to you

                        after more than 2-3 month, no more crash

                        i did change both transceiver and fiber!

                        but i think the issue was witthing the switch

                        i realise that does switch work in tandem port 49/50
                        51/52

                        i believe that the fact that a server was attach in port 49 the issue was cause by having the pfsense lan (dhcp/server) port plug into 50. so i put both server on 49/50 and add the lan fsense to 51.

                        crash never occur since then!

                          Huh? Switches don't care what ports you plug stuff into.. Sure you could have a bad port.. But sure doesn't care what you plug into ports that are next to each other ;)

                            SINCE TECHNOLOGY INS'T ALWAYS PERFECT ! THIS SCENARIO IS POSSIBLE !

                            maybe it's a bug inside the swith ! inside the software or firmware or whatever !

                            anyway my problem is fix since 2-3 month

                                So combo ports? Yeah you might wanted to mention such details off the top..

                                Guess should of assumed they were combo from the numbers.. But without details of the special ports your dealing with. They are not your typical common ports on a switch, which don't give 2 shits if server or whatever is next to each other.

                                    Tandem is not the term have ever heard used.. Been in the business 30 some years, before there there were even switches. Never heard the term used to describe a combo port sorry..

                                    Do a google for tandem port switch, nothing.. do a google for combo port switch.. Gazillion hits..

                                    Tandem how would define it just means next to each other, one behind the other, etc.
