Please Note:

WPA and WPA2 are both good encryption methods to secure your wireless network, and are more secure than WEP. However systems older than Windows XP Service Pack 2 do not support WPA encryption. If you have a wireless computer that pre-dates Windows XP Service Pack 2, you will have to use WEP as a security protocol in order to ensure connectivity of older machines.

Also, if WPA2 is available to you, it would be better to choose this option over standard WPA since it will allow wireless N devices to operate at their full capacity and network speeds if you have a wireless N router and wireless N network cards in the computers you are connecting.


  • First, open Internet Explorer or your preferred Internet Browser.
  • Go up to the address bar at the top of the page, and backspace everything out of it.
  • Next, type in the IP address of the router, by default it is
  • If everything is connected correctly, the browser will ask you for a user name and a password. By default, the user name is admin and the password is admin. Enter that, and press OK when done.
  • If the user name and password are accepted, the browser will load a TP-Link Status page.
  • To set up security, click Wireless on the left-hand side, then click Security Settings.
  • You will be brought to a Wireless Security page. To configure security select WPA-PSK/WPA2-PSK. Do not select just WPA/WPA2. This requires an authentication server to configure.
  • Change the PSK Passphrase to the password that you want on the router. It can use any character type, but has to be at least eight characters long.
  • Once you have entered the password, click Save at the bottom of the page. The router will then reboot. If you are on a laptop, you will need to reconnect to the wireless network during which you will be prompted for the key that was just set up. If the computer is a Windows 7 or Windows Vista based computer, you will have to remove the old network profile before attempting to reconnect to the router, or you will get an error saying The profile saved on this computer does not match the requirements of the network.
  • WPA or WPA2 Security should now be enabled on the router. You will need to enter this key into each wireless computer you add to the network. Wired systems do not require a network key to connect.
