 I downloaded and installed **RaspiOS 2020-05-27 Buster**, based on Debian 10. I choosed the **full** version "with desktop and recommended software".
-FIXME The WiFi is handled by Network Manager? The **/etc/wpa_supplicant/wpa_supplicant.conf** does conflict with Network Manager? The **/boot/wpa_supplicant.conf** trick explained in [[https://www.raspberrypi.org/documentation/configuration/wireless/headless.md|Setting up a Raspberry Pi headless]] does conflict as well?
+==== WiFi ====
+I installed the **Xfce** desktop environment; on Debian 10 this is bundled with the **[[https://packages.debian.org/buster/network-manager|NetworkManager]]** service, which handles wired and wireless connections.
+Beware that NetworkManager does conflict with the **/etc/wpa_supplicant/wpa_supplicant.conf** configuration file: if you configure a WiFi connection in this file, you will end-up with two **wpa_supplicant** instances conflicting each other (so you shouldn't even use the trick to [[https://www.raspberrypi.org/documentation/configuration/wireless/headless.md|setup a Raspberry Pi headless]]). Use instead the NetworkManager applet from the Xfce environment to connect to your WiFi network, the network preferences will be saved into **/etc/NetworkManager/system-connections/**.

 See the man page for **nm-system-settings.conf**, the article **[[https://fedoramagazine.org/randomize-mac-address-nm/|Randomize your MAC address using NetworkManager]]** and this **[[https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=196348&start=25#p1524581|post]]** on how to disable it on the Raspberry Pi.
+Alternatively you can uninstall the **NetworkManager** package and use **dhcpcd5** for all the network settings.
