Since the update to Ventura (Cleaninstall), network adapters reach 1000 Mbit via USB-C max. MacBookPro 16, M1max; Ventura 13.2 I use a 10GBit network, which worked very well under Monterey.
I had an OWC network adapter 10 GB in use. Since the update to Ventura, several tried adapters reach max 1000Mbit. I tried the following: OWC Thunderbolt 3 10G Ethernet Adapter WAVLINK USB3.0/USB C to 2.5G Ethernet Adapter D-Link DUB-E250 USB-C to 2.5G Ethernet Adapter Anker PowerExpand USB-C to Gigabit Ethernet Adapter
All max 1000 Mbit. With the OWC adapter, even a wrong IP was always assigned by the router via DHCP. For the others, at least that works. Although only max. 1000 Mbit, but that's annoying, because we installed a 10 GBit architecture in the office, which also cost money. And now max 1000 Mbit are in it.
I have also tried everything else, as some manufacturers installed the drivers. But that wasn't possible either. The installer said that the installation was successful, but after rebooting and reconnecting, the same driver version was displayed. I suspect that Apple must have taken them all out, and blocked all new drivers. Blocking is OK, but it has to be from Apple as it was the case under Monterey? By the way, the hotline recommends downgrading to Monterey. Does anyone know more? Because otherwise I can only do a downgrade.
