You are facing slow-speed internet. There is an urgent need for a mesh system. Like a Wi-Fi extender, a mesh Wi-Fi network is a solid option for extending your Wi-Fi range for the Linksys RE6400 Setup. Although the regular router may involve the use of more than two or near about two routers. But for that, you need to attach one of the extenders to the existing router. Begin the process by attaching one of the extenders to the existing router. Therefore do not forget to link the Mesh device to the different location of the house. These mesh devices work together to extend the range of Wi-Fi by producing an extended wireless network with a far larger coverage area than a single router.
