au QuaStation - Part 6 - Disabling the built-in Ethernet and WiFi

The Realtek chipset used by the QuaStation supports ethernet, but that is not connected to anything on the QuaStation.  It is best to disable this as follows:

systemctl -l disable ifup@eth0.service

WiFi can be disabled as follows:

systemctl -l disable ifup@wlan0.service

systemctl -l disable ifup@wlan1.service

systemctl -l disable ifup@wlan2.service

systemctl -l disable ifup@wlan3.service

RFKILL also works well and survives reboots. (Depending on the linux version it may not survive reboots, in which case, add to /etc/rc.local)

root@quastation4:~# rfkill block 1
root@quastation4:~# rfkill block 2
root@quastation4:~# rfkill block 3
root@quastation4:~# rfkill block 4
root@quastation4:~# rfkill list
