      Hello to all

      Im having some issues with a fresh installation of pfsense. i have tried two different builds:

      2.4.5-RELEASE-p1 (amd64)
      FreeBSD 11.3-STABLE

      2.5.0-RC (amd64)
      built on Wed Feb 10 09:40:34 EST 2021
      FreeBSD 12.2-STABLE

      My device:
      Lenovo m93p Tiny
      480gb SSD (Kingston 480GB A400 SATA 3 SSD SA400S37/480G)
      8gb RAM

      WAN NIC is a TP-Link USB to Ethernet Adapter (UE305)
      LAN NIC is the embedded on the device

      System starts good but out of a sudden, WAN connectivity will go down and i start getting a 502 Bad gateway error when trying to access pfsense web gui. After this, system is unresponsive except for ssh.

      when checking logs i see this:
      dhcpd.log will show some weird stuff

        USB NICs are generally a bad idea in pfSense.

        What is it connected to? It shows it's repeatedly losing link which triggers a number of scripts in pfSense. It is actually losing link?

        I would be running that as router-on-a-stick with VLANs rather than use a USB NIC if you can.

          thanks. long story short: it was the usb nic. AX88179 controller is a pita for pfsense
