Enter Password
It navigates to the “Edit Connection” window where the SSID of a given network is provided here. Move to the Password section and enter the credentials. After that, hit the “OK” button at the left bottom of the window:
Verify the Connected Wifi Network
The network manager command line interface (NMCLI) manages the network interface and specifies the possible internet connection. The “d” option is used to display the devices that are managed by the network manager. To verify the connected Wifi network, execute the below script:
$ nmcli d
The output shows that the “wlp6s0” device (wireless interface) has successfully connected to the Wifi network.
Method 2: Using GUI to Connect WiFi Ubuntu Server
The most common method is considered to connect the Wifi Ubuntu server via graphical representation. You should be familiar with the SSID and password to create a connection. For this, the step-by-step procedure is given below:
