    Hello, I have a fairly simple setup going on, however I am facing a strange issue.
    See, whenever I have 2 APs connected to the same switch connecting to the pfsense router, DHCP seems to stop working for devices that cannot randomize their MAC address, and then after waiting for a good while it works.
    Trying to set a static IP from on the device leads to the same problem but with ARP instead.
    I was hoping someone would help shed some light on this issue as I have been facing it for a while now to no avail.
    All switches are dumb switches.
    Pfsense is running virtualized in Proxmox, but I was facing the same issue with the same setup before migrating to Proxmox.

      @TheAmongler what version are you on? There was a DHCP bug in 23.09 that caused repeated entries. Fixed in .1 and 2.7.2.

      Pre-2.7.2/23.09: Only install packages for your version, or risk breaking it. Select your branch in System/Update/Update Settings.
      When upgrading, allow 10-15 minutes to restart, or more depending on packages and device speed.

        @SteveITS Thank you for your response.
        I was on 2.7.0 but updated to 2.7.2 and switched to the new DHCP backend but same exact issue still persists.

          @TheAmongler FWIW I would wait until Kea is out of preview as it has numerous limitations still. But for plain DHCP it should be fine.
