# 2021-07-27 explanation from @jvonau: The 3 BELOW (iw, rfkill, wireless-tools)
|
|
# are provided by RaspiOS. Ubuntu|Debian on the other hand are hit or miss:
|
|
# desktops might have some/all 3 preinstalled, while servers tend not to have
|
|
# these present at all, but are needed to be installed if you want to take full
|
|
# advantage of WiFi on Ubuntu and friends -- but it's only enforced on RPi
|
|
# hardware where we know in advance of the likelihood of WiFi being present.

- rfkill # 2021-07-27: RaspiOS installs this regardless -- enable & disable wireless devices
