Due to an error in the web address, "http://extender.linksys.com" should not be used for setup. The Linksys extender setup page's correct URL is "http://extender.linksys.com." The URL should be constructed with a colon and two forward slashes following the "http." This is what distinguishes the two.

The following steps must be taken to configure your Linksys WiFi extender:

Make sure your Linksys range extender is turned on and hooked in. Using your computer or phone, connect to the extender's default Wi-Fi network. This network should be marked in some way on the extender. Open a web browser and enter "http://extender.linksys.com" into the address bar. This is the proper URL. This link will take you to the configuration page for the extender. Configure your extender by following the on-screen instructions. They will show you how to choose your primary Wi-Fi network, enter your Wi-Fi password, and make any other necessary adjustments. Once you've completed the initial configuration of your Linksys extender, it should be ready to go and give you expanded Wi-Fi coverage throughout your home.

Finally, make sure you use the correct URL format when configuring your Linksys WiFi extender, which is "http://extender.linksys.com." This assures a successful installation and proper operation of your extender.
