When working in a weakly encrypted network, your data can be easily intercepted by criminals. If you are connecting to your home network and you receive a message that it is weakly encrypted, change to a more secure encryption type. The most common types of wireless network encryption are WEP, TKIP, WPA, WPA2 (AES/CCMP).
The protocols differ in their levels of security. We recommend WPA2, as it is the most reliable.
Router interfaces differ depending on the vendor, specific model and firmware version. For help navigating your router’s settings, see the user guide for your model. It is usually attached to the router, but otherwise you can download it from the vendor’s website.
As an example, we will show the settings from a TP-Link TL-WR841N router. To change your wireless network’s encryption type:
- Enter the router’s IP address in your browser’s address bar. You will be taken to the authorization page for the router’s settings. The IP address of the router is specified on the device and in the user guide.
- On the authorization page, enter your login and password. If you haven’t changed them, you will be able to find them on the underside of your router.
- On the router’s settings page, select Wireless → Wireless Security.
- Select WPA/WPA2 - Personal.
- Select WPA2-PSK from the Authentication Type drop-down menu.
- Select AES from the Encryption drop-down menu.
- Click Save.

Encryption will be enabled for the Wi-Fi network.
