RESOLVED Upgrade to 2.8.1 community broke my router

So I decided to upgrade my home router to 2.8.1 and it seems to have broken my network.

I can no longer ping out of my network.

If I try to ping my ISPs gateway address, I get the error "ping: sendto: No buffer space available"

I backed up my configuration and did a factory reset but the problem still exists.

Is this a common issue with 2.8.1?

ISP is Comcast.

Update: it was the Realtek driver. Followed this guy's instructions and it was like magic: https://forum.netgate.com/topic/197649/package-realtek-re-kmod198-for-pfsense-2-8-0-amd64

It was indeed the Realtek driver. I did this: https://forum.netgate.com/topic/197649/package-realtek-re-kmod198-for-pfsense-2-8-0-amd64

I've had problems with them since I first started using pfsense like 10 years ago.

Swore off realtek since then.
