LAN port hangs when using Web UI

I'm new to pfSense and have a strange problem. When I'm in the Web UI, the LAN port will randomly hang. I'm able to log into the pfSense console directly on the server and ping external hosts (i.e., www.google.com or www.amazon.com), but not internal hosts (i.e., 192.168.1.59). I've had days go by with the system stable, but I'll log into the web UI and just by looking at things, the LAN port will hang. Rebooting pfSense fixes the problem.

pfSense is running on a 1U SuperMicro SYS-5018A-MLTN4 with an Atom processor and Ethernet ports that report as "Intel" through the pciconf command. They are integrated with the motherboard. The WAN port goes to my cable modem (xfinity) and the LAN port plugs directly into a 24 port un-managed switch.

I've looked through the logs in /var/log and don't see any errors. Is there somewhere else I can look to understand what's going on? Is there a way to get more details on why the port isn't responding?

When this happens what does the LAN interface status show?
Try running ifconfig -vvm igb1, assuming LAN is igb1.

That system has 4 NICs in the SoC. Try re-assigning the LAN as one of the others, see if the problem follows the config.

I think I may have fixed it. I have three eero wifi access points on my network in bridge mode. I had all three connected via ethernet to my main switch. I found this article: https://www.reddit.com/r/eero/comments/mi533y/configuring_eero_with_pfsense/. I re-configured my network to have one eero connected to my main switch and the other two access points connect via a secondary switch connected through the second port on the main eero device.

Everything seems stable now, though I don't know why the original configuration "worked" for long stretches of time.

Agreed... even the new network topology didn't keep the eero devices from interfering with pfSense eventually (just took a little longer for the same symptoms to appear). I replaced the eero mesh with some Netgear wifi access points and the network has been stable ever since.
