How to configure WEP/WPA Security on a linksys wireless router / access point

Step 1: Login

  • Open your Internet browser and enter the following in the address bar: http://your_routers_ip.

By default, the address is 192.168.1.1.

  • Enter the user ID and password for your router. The default password is admin.

Step 2: Limiting the no. of users connecting through DHCP

  • You should now see the Basic Setup Web page display in your browser. Scroll down the page until you see Maximum Number of DHCP Users.
  • This option will assign a specific number of IP address to computers. If more than this number of computers tries to connect to your router, they will not be able to.
  • Count the number of computers that will connect to the router, and type it into the Maximum Number of DHCP Users textbox.
  • Scroll down to the bottom of the Web page and click Save Settings. Once the settings have been saved, click Continue to return to the Web page.

Step 3: Change your Admin Password.

  • At the top of the Web page, click the Administration option in the menu bar.
  • On the Management Web page, you should see two password text boxes. This is where you should * change your administrative password. Type in a new secure password into both boxes.
  • Once you have typed in your password, click Save Settings at the bottom of the Web page.
  • You may be prompted to login again, if you are then enter you new password in the password field.
  • Navigate back to the Management Web page by clicking the Administrative option in the menu.

Step 4: Encrypting Traffic

We will now encrypt your connection to your router setup from your computer.

  • Click the HTTPS checkbox next to the Access Server option.
  • Once again, click the Save Settings button at the bottom of the Web page.
  • You won’t get the settings saved page again because the URL in the address bar is not longer correct. Since you have changed your connection to HTTPS, it you need to specify that in the address when you connect to the router setup.
  • In your browser, change the address to: https://192.168.1.1. If you get a security error, ignore the error and continue to the Web page.
  • Login with your password and then click the Wireless menu option.

Step 5: Specify an SSID

  • Beside the Wireless Network Name (SSID) option, type in a name for you network connection.
  • Click the Save Settings button and the Continue button to return to the Basic Wireless Settings page.

In order for DHCP to work when WEP is enabled, the SSID Broadcast setting must be set to “enabled”.

Step 6: Assigning WPA

  • Click the Wireless Security sub-menu option at the top of the page. This is where we will provide the most important security setting.
  • Next to Security Mode, select WPA – Personal from the drop-down list. If you have trouble connecting to your wireless connection, you can try selecting WEP, but your connection will be much less secure.
  • Next to WPA Algorithms, select AES. Once again if you have trouble connecting to your wireless router, select TKIP.
  • Specify a long WPA Shared Key with a mix of upper and lower case letters, numbers and punctuation. The longer the better.
  • Make sure you write down this key somewhere, either on a piece of paper or in a text document on your computer. You will need this information when you connect to your wireless network.
  • Click the Save Settings button at the bottom of the Web page, and then the Continue button.
  • Now you are all done securing your wireless router and network.

After Securing how do you connect to the network?

  • Connect to your network, and enter your WPA Shared Key exactly as you specified it.

Why WPA and not WEP?

The previous standard called Wired Equivalent Privacy (WEP) was easy to crack within about 30 seconds. The new Wi-fi Protected Access (WPA) is more secure and should be enabled. You must also choose a passphrase that will be needed for each computer to connect to your router. Choose a passphase that is long, hard to guess, but easy to remember. Write it down somewhere so you don’t forget it.
