To start using and enjoying your new Linksys re6400 extender, you will need to set it up. But, you might find the setup process difficult if you are a non-technical user. Don’t worry, the WPS method is a simple process that you can execute easily in a few minutes. In this Linksys re6400 setup process, you will only need to press the WPS buttons from the extender and your router. Once you do that, the setup will be done shortly and the stable LEDs will notify you. But, make sure you place both devices closer to each other while setting the extender. However, don’t choose the area where the electrical appliances are placed. After the setup, you can relocate the extender to a different place keeping it within the router’s range. In doing so, there will be no WiFi dead spots at your place as the extender provides better WiFi coverage.
