A few days ago I purchased this Dock and it was working perfectly. Then I installed the Big Sur 11.2 beta 2 update (build 20D5042d). I was running 11.2 Beta 1 before. Now the Ethernet will not acquire a DHCP lease. I’ve tried removing and re-adding the interface from the Network settings in System settings to no avail. It just self-assigns an IP address with no connectivity. FYI, using a M1 13" MacBook Pro.
I suspect this is a Big Sur problem, but I do want plugable and other customers here to know about it and feel free to offer any suggestions.
Update: I tried an Anker USB-C ethernet dongle and it works fine, so… maybe something with the chipset/driver in the Plugable?
