This is the wifi guide for the Linksys WRT51AB. We also have the following guides for the same router:

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.


You should almost definitely pick WPA2 for your networks encryption. If you are unsure, be sure to read our WEP vs WPA guide first.

This is the setup page from your Linksys WRT51AB router.

This option opens up a page that unfortunately we don't have. In this section you are asked to create an SSID. The SSID is the network name you give your connection so you can identify it later. I recommend avoiding personal or router specific information. Learn more in our How to Change your Wireless Name guide.

After that is the Channel. If you want to change the channel you do that by opening the drop down box labeled Channel. I recommend using only channels 1,6 or 11.

Next you should choose the type of security mode you want to use. You may only have the option for WEP security. This is not advisable to use this option. Learn what his is and your other options in our WEP vs. WPA guide. My recommendation is to use WPA2-PSK. If you don't have this option you should update your firmware.

The last setting you need to change is the Passphrase. I recommend using at least 14 to 20 characters. It is important that you create a strong password. Learn more about this in our Choosing a Strong Password guide.

When you are finished click the Apply button to save your changes.

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.
