There as an a naming inconsistency issue with my ax201 wifi device, but after a recent Xen upgrade, it looks like it was all gone. So we can move to the next step
Since the device is consistent, wpa2 networks survive without manual intervention after suspend/resume and docked/undocked boot scenarios.
But my wifi6 network cannot. So i have investigated a little bit and noticed that
- suspend/resume reproduces the problem
- unloading iwlmvm and reloading it reproduces the problem
- during the wifi device emits interesting logs such as it thinks a WPS PBC is in progress
- a way to recover is to reboot the sys-net qube (and sys-firewall perhaps)
Nothing happens by itself. I thank deeply for the device enumeration fix. I guess some more effort is needed at the Xen level to cure this for wifi6.
