2. Enabling encryption
Note down the following points:
- Use of 128-bit encryption or more is highly recommended for making the Wireless Network more secure.
- WEP and WPA are different encryption schemes.
- WPA is more secure than WEP but is harder to set up correctly.
- Purchase an access point that has WPA2 encryption as it is highly recommended as the perfect encryption scheme,
- WPA2 uses a static Pre-Shared Key which is easy to capture, so use a very long password which is at least 10 alphanumeric characters.
- Another option is to use a RADIUS server and the WPA2- Enterprise mode.
- This will help you set up a username/password combination and generates temporary session encryption key.
- Setting up your own RADIUS server is difficult to configure, so use the commercial Virtual RADIUS server.

- You will implicitly be forcing your computer to shoot your SSID when trying to connect.
- This might help anyone impersonate you router and obtain your information.
