During the Linksys Extender setup process, users are mostly advised to perform the setup process through the Smart Setup Installation method. When a user runs the Smart installation setup, your extender automatically scans for the available Wi-fi network in your area. You can also use the Smart Setup in order to bring changes in the various kinds of settings of the range extender through the extender.linksys.com window. You must know the Wi-fi password of your router’s network to connect your range extender to the main router within the network.
