How to setup a repeater?
Currently the router is located at the opposite side of the house. It delivers extremely weak signal into my room. I’ve been connecting a 20 metre ethernet cable to a switch that links to my PC and other devices with Ethernet support. Recently, speeds to my laptop, phone, and iPad have become noticeably slow. To improve this, I bought a GL-AR300M16 repeater to extend the signal. Its setup guide only explains using it as a Wi-Fi repeater. I need a way to connect from the modem directly to the main router, then to my switch, which in turn links to the PC and other wired devices. From there, the mini router broadcasts the main router’s network. Is this configuration feasible with this model? If not, it’s fine—I can replace it—but I’d like clear instructions on exactly how to set it up as described.
Without a mesh setup, smooth roaming is unlikely. Simply reusing an existing network works just like connecting another access point directly to the wired LAN, but a repeater consumes half the WiFi capacity and isn’t really worth it.
Choose between converting the old router into an access point (same SSID works but isn't perfect) or turning it into a repeater. The best choice is to purchase a mesh system, configure it as your access point, disable the existing network on your current router so the mesh becomes your primary Wi-Fi source, or set the mesh as your main router with the old one acting as a switch. Entry-level options include TP-Link Deco X20.
"Mesh" refers to a marketing concept often tied to 802.11krv protocols. Not every device that claims mesh capability will work with these standards. Even if it does, real-world impact is minimal unless you're constantly moving around. Having many access points that all backhaul support KRV is perfect but not crucial if the necessary standards aren't present.
From a technical standpoint, purchasing a mesh system paired with wireless backhaul usually performs worse than simply deploying several wired APs in key spots. Reasons include: WiFi operates in half-duplex mode, causing nodes to waste half their capacity and adding delay at each connection point. This effect intensifies with more hops. While triband solutions help, they aren't flawless.
Repeated transmissions also consume valuable spectrum, and placing wired APs in optimal indoor locations—like atop ceilings—maximizes signal strength. Wireless mesh configurations demand careful planning of node placement relative to the central network, introducing numerous trade-offs.
A common criticism of the GL-AR300M16 is its low-end status and limited support for WiFi-4 from 2009. Using it in AP mode with a different SSID and only connecting low-performance devices can improve performance somewhat. A more capable AP model would generally yield better results.
