WiFi Terms

Before we get started there is a little bit of background info that you should be familiar with.

Wireless Password

An important part of securing your wireless network is choosing a strong password.

Wireless Channel

Picking a WiFi channel is not always a simple task. Be sure to read about WiFi channels before making the choice.

Your Enable Wireless Networking should be on by default. If you see that it is not marked, go ahead and check this small box.

Next is the Wireless Mode. Choose Mixed.

Below that is the Channel Selection. In the United States the three channels that should always be used are 1,6, and 11. For more information on why you should only use these three channels check out our guide on WiFi channels.

Then, in the box labeled Service Area Name/SSID there are two different things you can do. The first is enter the wireless name in the box labeled Service Area Name/SSID. This is the name of your network. Don't include any personal information here. We have a great guide on the subject if you want to know more about wireless names. The second option in this box is Enable Broadcast SSID. By default this should be Enabled. If you want to broadcast your SSID or network name, your network is visible to all the surrounding networks. If you want to keep your SSID hidden, it is invisible to the general public but not to a scanning tool used by hackers.

When you are finished with these changes, go ahead and click Apply.

You need to choose the type of security encryption to use. Click the option on the top of the page labeled Encryption.

You should now be on a page that looks like the one you see above.

There is only one option available on this page. The Security Mode is a very important security feature that shouldn't be overlooked. Use this drop down menu to choose WPA2 Pre-Shared Key. WPA2 is the strongest encryption available today. For more information on the different choices check out our WEP vs. WPA guide.

At this point, a new box should appear asking for a Pre-Shared Key. This is referring to the network password. This is extremely important for your network security. Make sure that this password contains no personal information, or any word you can find in a dictionary. Do use symbols, numbers, and capital letters. For more help in creating a strong password check out our creating a strong password guide.

That's it, you did it!

Possible Problems when Changing your WiFi Settings

After making these changes to your router you will almost definitely have to reconnect any previously connected devices. This is usually done at the device itself and not at your computer.
