In my ipfire setup, I’m using multiple wifi networks as wireless client. I setup every wifi network with different priority.
After some testing and rebooting, It turned out, that wifi networks with higher priority numbers are preferred over wifi network with lower priority numbers.
So it’s quite opposite as described in documentation wireless client and wireless client setup page.
Can devs double check my findings and make fixes in documentation and wireless client setup page.
Also documentation for wpa_supplicant confirms my findings.
