WiFi Terms

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

Wireless Name

Your wireless network needs to have a name to uniquely identify it from other wireless networks. If you are not sure what this means we have a guide explaining what a wireless name is that you can read for more information.

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.

This is the wifi setup page from your Linksys router.

On this page you are asked what Wireless Configuration you want to use. If you choose Wi-Fi Protected Setup you are taken to a page like the one you see here. Do not use WPS or Wi-Fi Protected Setup. This becomes a weak link in your security. Read our What is WPS Guide.

Click the Manual radio dot at the top of the page. This takes you to a page that unfortunately we do not have. The first setting should be called Network Mode. This can be left at Mixed.

Below that is the Wireless Channel. Make sure you use channels 1,6, or 11. To learn why, read our WiFi Channels Guide.

Now find the box labeled SSID1. This box needs to contain an original name that you create in order to identify your wireless connection. It doesn't matter what you enter here but we recommend avoiding personal information. Learn more about this topic by reading our Wireless Name Guide.

Once you are done, click the Save Settings option at the bottom of the page.

Then back at the top of the page, click Wireless Security.

On this new page, use the drop down list titled Select SSID to highlight the SSID you created on the last page.

You are then asked for the Security Mode. The best option for home networks is WPA2 Personal. If you are interested in learning why we recommend this one, read our WEP vs. WPA guide.

Use the WPA Algorithms list to choose AES.

The last thing you need to enter is the WPA Shared Key. This is the password you type into any wireless device you want connecting to your network. We recommend creating a strong password of at least 14-20 characters using a mix of symbols, numbers, and letters. Read more in our Choosing a Strong Password Guide.

That's it, you did it, just click the Save Settings button and you are done.

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.
