Mobile Proxmox on Laptop - WiFi + NAT vmbr0 doesn’t work

[jolly.rodger]

Hi. Can you please help to solve this problem.

I tried to install proxmox ve on my laptop, no success. works fine only with ethernet cable and default config.
can't get wifi working with vmbr0. any ideas why? also wpa_supplicant is super slow.

ideally, i want a mobile workstation for proxmox on wifi with dhcp, if it possible

WiFi isn't supported on PVE. It's possible to set it up, since it's a regular Debian under the hood, but especially bridges work very poorly (WLAN in general doesn't like multiple MAC addresses per AP client). We have a wiki page for some assistance: https://pve.proxmox.com/wiki/WLAN
