That said, the more devices you add, the trickier troubleshooting becomes, as each device can form a critical part of the home network connectivity chain: one weak link can result in no internet connection. Mesh WiFi systems let you effectively add additional compatible WiFi satellites that act as routers, which means better and more consistent signal strength, all on which is treated as a single local network. Routers play an important role in your connection to the internet. In many respects, WiFi extenders are old tech when stacked next to their successor: the mesh WiFi system. Routers provide multiple ethernet ports for wired connections and produce a Wi-Fi network for wireless connections.

These networking devices are designed to mirror and extend an existing WiFi network. If your internet is slow, you can always make use of a WiFi extender, booster or alternatives. Not only are the devices on two different levels within the network, but they perform different functions: modems transform signals coming into and going out of. Data storage and backup of huge capacity. In fact, the routers are a basic building block of the mobile communication system. WiFi extenders are handy for larger homes that want to expand the signal of a WiFi router to far-reaching parts of the home or outside. The use of the modem is limited to only LAN connectivity but the routers are used for LAN as well as WAN communication networking. Technically, a modem can connect directly to a networking switch, but this would eliminate wireless connectivity in the home. For homes that want as many Ethernet connections as possible, a networking switch can connect to a router to further delineate local network traffic, whereby the router can mainly tackle wireless connections, and the switch takes care of wired connections. There are a couple of other networking gadgets in the home that are designed to liaise with a modem, a router, or a modem-router.
