Making it a VM isnt really fixing the issue. It's a workaround with impact on performance, plus now you have to manage Promox.

I know, but my purpose was to find out if the problem was caused by me making mistakes in my settings or the driver. The VM Opnsense has been stable for five days, so I am pretty sure the problem was with the driver. Surprisingly, I didn't see many people reporting this problem, so I wonder if a combination of driver issues and my settings causes it.

I just wanted to leave a quick note here that after upgrading to 25.7.5, the system has been running smoothly for more than a week without dropping connection. Hopefully, the underlying program has been fixed.

I have tried all the suggestions in this thread, and nothing worked.

An arp issue would be very strange considering DHCP is working ok.

Do you have IPv6 enabled on WAN side? If so try disabling IPv6.

I did have IPv6 enabled. I will try to disable it and see if that makes any difference.

On the other hand, I have installed Proxmox on the N350 mini pc router, then Opnsense as a VM. It has been more than 24 hours, and the router has been stable so far.

I want to chime in and say I have had the same problem of WAN experiencing 100% Packet Loss periodically since upgrading to 25.7. I have two CWWK mini PC routers, one with an N100 CPU and the other with an N350 CPU. Both come with four i226 ports. I have a Verizon Fios connection (residential).

The 100% packet loss happens about once a day. Interestingly, when the N350 mini PC router experienced 100% packet loss, the machine continued to function on the LAN side, but with no WAN connection. I reviewed all the logs but couldn't find anything wrong. When the N100 mini PC router experienced 100% packet loss, it would reboot itself, and the WAN connection would come back.

I have tried all the suggestions in this thread, and nothing worked. Here are the things I have tried:

• Setting hw.pci.enable_aspm to 0 didn't make a difference.
• Setting hw.igc.eee_setting to 0 didn't make a difference.
• I have checked the WAN DHCP leases, and it seemed to work as expected.
• I have turned off VTd in the BIOS, but it didn't make a difference.

For my next troubleshooting step, I will install Proxmox on one of the mini PC and virtualize Opnsense to see if the problem still persists. 

I just wanted to thank you for sharing your experience. Your post helped me set up IPv6 in my box.
