hot-spotwireless
I am using my Ubuntu LTS 18.04 to hotspot an internet connection to various other devices, but I would like this to be the default configuration, but when I restart the system I currently have to switch the hotspot on again each time.
How can I make the hotspot the default setting for my wifi device?
The method described in this answer only works if your wireless device supports master mode. To check whether it does, open a console and type
sudo iwconfig wlan0 mode master
Replace wlan0 with whatever Ubuntu calls your wireless device.
If you get an error, your device does not support master mode and this solution unfortunately does not work. Source: Community Help Wiki, this comment.
Disable WIFI and plug in an internet cable or mobile-broadband modem to your Ubuntu so that your Ubuntu is connected to wired or broadband connection and wireless is disabled.
Go to Network Icon on the top panel → Edit Connections, then click the Add button in the pop up windows.
Choose Wi-Fi from the drop-down menu when you're asked to choose a connection type:
In the next window, do:
Go to Wi-Fi Security tab,select security type WPA & WPA2 Personal and set a password.
Go to IPv4 Settings tab, from Method drop-down box select Shared to other computers.
When done, click the save button.
After above steps, a configuration file created under /etc/NetworkManager/system-connections directory. File name is same to the connection name you typed in step 4.
Now press Ctrl+Alt+T on keyboard to open terminal. When it opens, paste the commands below and hit Enter to edit the configuration file.
gksudo gedit /etc/NetworkManager/system-connections/wifi-hotspot
Replace wifi-hotspot with the connection name you types in step 4.
When the file opens, search for the line mode=infrastructure and change it to mode=ap.
Finally save the file.
When everything's done, enable WIFI from Network Manager icon on the panel. It should automatically connect to the hotspot you created. If not, select "Connect to Hidden Wi-Fi Network" and select it from the drop-down box.
Now you can search and connect the access point from your Android mobile ..... enyou <^_^>

you can do it with Network Manager. Check the name of the connection which represents the hotspot that you want to start when its active or just guest
nmcli con show
then to make it start automatically
nmcli con mod <connection-name> connection.autoconnect yes
test it with reboot

Workaround
Ok, Instead of Turning the Hotspot on via GUI Every time.. you can add a Startup Applications Preference for your Hotspot Connection..
to add the command to Startup Applications Preferences, you need to know your connection name..
to know the connection name..
either run
nm-connection-editorand look for the required connectionor once the Hotspot is on, run
nmcli device show | grep GENERAL.CONNECTION:Example:
So the required connection name is
MyHOtSpotto turn on and off this connection, the below commands are used..
So to turn on the HotSpot at every boot..
add the command
nmcli connection up MyHotSpotto Startup Application Preferences like thisthe below pic is a automatic gnome-screenshot with delay of 10 secs after a reboot which shows Hotspot is On.
