Creating wifi-hotspot using Unity's default network manager without downloading any tool/software.
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
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:
- Type in a connection name. The name will be used later.
- Type in a SSID
- Select mode: Infrastructure
- Device MAC address: select your wireless card from drop-down menu.
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.

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.
