USB-C to ethernet adapters broken on ventura?

[MBHockey]

I have a Macbook Air M1 and an Mac Studio M1 Max. i cannot get two different gigabit ethernet adapters to work on either computer, it seems, since i upgraded to Ventura.

I have the Belkin one that i purchase directly from Apple this week and another one i have been using for two years i got off Amazon. neither are able to get an IP on either the MBA or Mac Studio.

I use the adapter just for the MBA to test my LAN. it's helpful to bring a laptop directly to my rack and have an ethernet port to directly plug in there. But now it doesn't work. I was only testing it on the Mac Studio to see if it was a problem with my MBA, but it seems neither computer use it.

I have already turned on the 'always allow' for accessories to connect to the MBA (new setting in ventura)

Any ideas?

TL;DR: works for me

I haven’t run into this with any of my Ventura Macs (all hardwired, some Intel and some Apple Silicon) and the fact that you have two different computers and two different adapters failing is interesting.

I’m wondering if the Ventura upgrade is more of a coincidence than a cause; are you sure your router is behaving correctly? When was the last time you rebooted it? Have you taken your M1 MacBook Air and its adapter and tested it elsewhere?

Or simply connect the MBA with adapter directly to the Studio Ethernet port, set one to static IP 10.0.0.1 and the other to 10.0.0.2 and see if they can ping each other.

It isn't the router. the LAN is fine. Plugging the same ethernet cable that was in my Mac Studio into either adapter going to the MBA or Mac Studio's USB-c port does not work.

Interesting -- so yeah, this does work. I can ping each computer from the other one when directly connected to each other with the ethernet cable and assigning static IPs. So traffic works. It's just some issue with getting an IP from the DHCP server that seems broken.

Similar issue here - the router is v.good for all other devices on the network, but either EN port on a 7.1 mac pro will just not get an IP from the DHCP server, instead gives the dreaded 169.x.x.x IP address; wifi will connect OK. Have also set up a fixed IP address on the router and the mac; this shows that it is connected in the Network panel, but still cannot connect to the internet, again only wifi works. PITA.
