Cannot connect to internet with big sur public beta 2

Public beta 1 seemed to work great on my early 2015 macbook pro.

Since upgrading to public beta 2, I am completely unable to connect to the internet. I tried both wifi, and wired connections (ethernet via thunderbolt monitor).

On wifi, network preferences shows a green connected dot, but I am unable to access the internet via any browser or other program.

I have tried:
renewing dhcp lease
deleting network preference plist files and rebooting
reinstalling big sur from recovery mode
creating a new network location

Network diagnostic report shows basic connectivity failure.

Any suggestions on what to try next?
I did a recovery boot reinstall, and got the newer build (20A5364e) but still no internet connection.
Any recommendations?
