You can take the help of the Link LED of your router to determine a good location to fix your range extender during the extender.linksys.com setup process. When the Link LED of your router turns red, it means you need to bring the extender closer to your router to gain a sufficient amount of Wi-fi signals. If the Link LED of your range extender turns blue or amber, it means your extender is already in a good position or the distance between your extender and router is enough to get a robust amount of Wi-fi speed.
