Using Network Manager icon
I just found out that the Gnome Network Manager applet can create an access point automatically. It calls it "Hotspot" and it can be enabled by going to the WiFi page and clicking the "Turn On Hotspot" button at the bottom of the page. The first time it is turned on it creates the file /etc/NetworkManager/system-connections/Hotspot. The access point is hidden by default but that can be changed by editing the Hotspot file.

- I have just discovered the same with KDE. In Network Manager pop-up (a panel which shows when you click in system tray icon) you can just click Wi-Fi Acess Point. As I could see, it applies the good ap settings automatically in the meaning of channels/standards or some another parameter, because when I tried with wihotspot, the signal strength was low, and when tried with Network manager icon the signal strength was maximum. Again, maybe it is possible to configure it correctly in wihotspot, I just did not explored this yet.
- NM icon method is by default without password. But it is easily possible to create a password protected wireless access point manually. Go to Connections settings -> Press "+" button (Add new connection) -> Choose Wi-Fi (shared) -> Press Create -> Set wanted values. Than just click on that newly created connection (do not use the Wi-Fi Acess Point button). NM will up the AP connection while keeping the ethernet connection active (in my case internet is incoming via ethernet). Ashark (talk) 19:07, 9 February 2021 (UTC)
