The users are unable to connect to both wireless as well as wired Internet. As far as wireless is concerned, the patches for T2 Macs that have been upstreamed in kernel 6.3 have been working well till 6.2.2, but after that the network has stopped working. > > Interesting, the driver shows no errors in journalctl.

Ethernet/USB tethering has also stopped working. > > If I you need some logs from me, please do ask. > > Also, Hector, I’d like to know whether this affects the M1/2 Macs as well or not. This is already reported, identified, and a patch submitted. https://lore.kernel.org/linux-wireless/20230124141856.356646-1-alexander@wetzel-home.de/ - Hector
