I shipped it all back to Lenovo yesterday because I couldn’t make it work, but what I had was:
Lenovo P14s Gen 5
ThinkPad Thunderbolt 4 Workstation Dock
The laptop definitely supported Thunderbolt, but I had insurmountable problems if I connected the dock before booting the machine, so I was connecting it after Qubes had already started. Maybe that also impacted how it connected (USB vs Thunderbolt)? I don’t know.
I wrote a thread here that has some detail of my experiences. HCL - Lenovo P14s Gen 5 (21ME001LUS) - #3 by danny
As far as the AX211 NIC goes, I know in theory the card should work, but I had the exact problem described here. QCNFA765 (wcn6855) WiFi6 controller not working - #9 by Jakob Since that thread is 2 years old with no solution posted I figured I would not get anywhere in the time remaining before my return window closed.
Thanks for responding. I’ve always used desktops and I am pretty ignorant of laptop technology like Thunderbolt. When I bought the laptop I thought Thunderbolt was its own thing separate from USB, which would align with what you’ve just described, but after I had these problems I came across articles saying it is more or less just the Intel-branded version of USB4, so I thought sys-usb must be in play. That seemed to jibe with my experience because if I turned on sys-usb during the install, then the machine would completely stop accepting input early in the boot process and that didn’t happen if I installed without sys-usb.
