To scan for available wireless networks on Ubuntu, you can use the command-line tool called "iwlist." Here's how you can do it:

  1. Open a terminal by pressing Ctrl+Alt+T or searching for "Terminal" in the applications menu.
  2. In the terminal, type the following command to list the available wireless interfaces on your system:iwconfig Note down the name of the wireless interface you want to scan for networks. It is usually named something like "wlan0" or "wlp3s0".
  3. Once you have the name of the wireless interface, use the following command to scan for available networks:sudo iwlist <interface_name> scan Replace <interface_name> with the name of your wireless interface.For example, if your wireless interface is "wlan0," the command would be:sudo iwlist wlan0 scan
  4. Wait for a few seconds while the scan is performed. You will see a list of available wireless networks along with their details, such as SSID (network name), signal strength, encryption type, and channel.


That's it! You have successfully scanned for available wireless networks on Ubuntu using the command line.

Alternatively, you can use the graphical user interface on Ubuntu to scan for available wireless networks. Here's how you can do it:

  1. Click on the network icon in the top-right corner of the screen. It looks like a Wi-Fi symbol.
  2. In the dropdown menu that appears, click on "Select Network."
  3. A list of available wireless networks will appear. You can click on the network you want to connect to and enter the password if required.
  4. If you want to see more details about the available networks, click on the "Wi-Fi Settings" option at the bottom of the dropdown menu. This will open the Network Settings window where you can see a list of available networks along with additional information like signal strength, security type, and MAC address.


Using the graphical interface is a more user-friendly way to scan for wireless networks on Ubuntu, especially if you prefer not to use the command line.
