Key features – TP-Link Deco S4 3-pack (review)
TP-Link Mesh: With advanced Deco Mesh Technology, units work together to form a unified network with a single network name. Devices automatically switch between Decos as you move through your home for the fastest possible speeds.
Whole Home Coverage: Deco uses a system of units to achieve seamless whole-home Wi-Fi coverage up to 3,800 sq.ft.†— eliminate weak signal areas once and for all! And if that’s not enough, simply add more Decos to the network anytime to increase coverage.
Connect More Devices: Deco can handle traffic from even the busiest of networks, providing lag-free connections for up to 75 devices†.
Fast Dual-Band WiFi: Deco S4 provides fast and stable connections with speeds of up to 1167 Mbps† and works with all internet service providers (ISP) and modems.
Easy Setup: Setup is easier than ever with the Deco app there to walk you through every step.
Parental Controls: Parental Controls limit online time and block inappropriate websites according to unique profiles created for each family member.
How does this work when it is in access point mode? Do they have to be wired into the main modem?
Yes, in access point mode you wire them via Ethernet cable to your main modem. This is different than using it as a true mesh system where the individual units transfer data wirelessly from one to the other back to the modem. I set mine up as access points, one on each floor of my three story home. I had single Ethernet drops on each floor from my AT&T main router so it was relatively easy. Like most isp providers, the unit from AT&T is a combination modem/router, so I turned off the wireless capability on it so it wouldn’t interfere with the Deco units. The primarily advantage of this setup is wired backhaul, which is generally faster than the wireless backhaul when used as a mesh system. Obviously the disadvantage is the need to have the Ethernet cables in place to support it. In my case coverage and speed have improved greatly. Wish I had done it years ago.
When you add a new device to the WiFi network which password do you use (mesh or WiFi password)
You use the mesh password. This doesn’t preclude you from logging in to the provider’s wifi router, but for simplicity’s sake you should use the mesh network as your primary connection. The mesh network essentially extends the wifi connection as if you had a long, long ethernet cable from your internet router. The mesh network also assigns its own dynamic IPs, so you would also want to re-configure any wifi printing devices, televisions, etc. to connect to the mesh network, so that everything is on the same network SSID.
