To add a wireless network in Ubuntu, follow these steps:
- Click on the network icon in the top-right corner of the screen. It looks like two arrows pointing up and down.
- Click on "Wi-Fi Settings" at the bottom of the drop-down menu.
- Click on the "Add" button to add a new wireless network.
- Enter the name of the wireless network you want to connect to in the "SSID" field.
- Select the security type used by the wireless network from the "Security" drop-down menu. For example, if the network is using WPA2 encryption, select "WPA2 Personal."
- Enter the wireless network password in the "Password" field.
- Click on the "Save" button to save the network settings.
- Click on the network icon again, select the newly added wireless network from the list of available networks, and enter the password to connect.
If you have any trouble connecting to the wireless network, ensure that your wireless adapter is enabled and functioning properly, and that you are within range of the wireless access point.
