Big Sur beta 4 networking issues

I have lost networking since beta 4 came out. With TCP dump, I see packets bidirectionally. But I can’t get to websites or ping my own GW.

I get a IP address via DHCP.

If I try to ping a site like Cisco or amazon, I see the DNS name is resolved but still says no route to network. My routing table looks good on my Mac and every other device can get out. So I know it is not my home network.

Anyone else see this? I really done want to rebuild my machine.

Had the exact same issue. Had to rebuild my machine. Worked for maybe 30 seconds upon boot-up, then no internet connectivity (even though the Network panel indicating the device had an IP address).
