I set up OPNSense on a Lenovo ThinkCentre M720q Tiny (Intel Core i5-8400T, with 8gb ram) back in May with a GLOTRENDS LE8245(A3) amazon (https://www.amazon.ca/dp/B0FSJR3GZY?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1). Was working great until a week ago when I updated to OPNsense 26.7.4_1-amd64, FreeBSD 15.1-RELEASE-p3, OpenSSL 3.5.8.
When I first upgraded within a hour I had to reboot as all LAN devices lost wifi. A week later in this is happening frequently. I can still reach the OPNSense box through wan (tailscale), but all lan devices lose wifi. I reboot and works for some time.
In the logs, I do not see any errors under 'System > Log Files > General', except the weekly '2026-08-25T02:31:09Erroropnsense/usr/local/etc/rc.linkup: Interface lan tracking nonexistent interface wan'.
I installed the plug-in 'os-realtek-re', issue still persists. My connection is PPPOe with a vlan that my ISP requires, modem is a simple media converter box (optical to RJ45). How do I diagnose and fix this? Worked with no issues over 4 months before upgrading.
This is your issue :

Dump the NIC and replace it with any Intel Quad Port NIC and you are DONE! :)
I figured it was the driver's or nic. But it worked fine before upgrade. What dual 2.5gb Intel would fit? I see mostly Chinese randoms with 'intel' chips.
