For a 3-story house with 50+ connected devices, I’d go with a tri-band Wi-Fi 7 mesh system, and the TP-Link Deco BE65 is a particularly strong fit.
Recommended: TP-Link Deco BE65
The BE65 is designed for high-density homes and supports 200+ connected devices, so 50+ devices is well within its stated capacity. It is a tri-band Wi-Fi 7 system with 6 GHz, 5 GHz, and 2.4 GHz bands, plus Multi-Link Operation (MLO) and 320 MHz channels.
For a three-story house, I'd use a 3-pack, with one Deco on each floor. If you can run Ethernet between floors, even better: use wired Ethernet backhaul. That allows the mesh units to communicate without consuming wireless bandwidth for the backhaul. TP-Link also supports both wired and wireless backhaul.
Why it fits this situation:
- 50+ devices: Designed for high-capacity environments; TP-Link states support for 200+ devices.
- Three floors: A 3-unit mesh gives you much better placement flexibility than relying on one powerful router.
- Wi-Fi 7: Includes 6 GHz, MLO, 4K-QAM and 320 MHz channels.
- 2.5GbE: Each unit has four 2.5Gbps Ethernet ports, useful for high-speed wired devices and Ethernet backhaul.
- Smart roaming: Devices can move between Deco units while remaining on the same network.
- IoT support: You can create a separate IoT network, which is useful when you have dozens of smart-home devices.
How I'd set it up
Floor 1: Main Deco → connected to your modem/ONT
Floor 2: Second Deco → preferably Ethernet-connected
Floor 3: Third Deco → preferably Ethernet-connected
Don't put the second and third units at the extreme edges of each floor. Put them in relatively central, open locations where they have a strong connection to the previous node.
One important point: don't choose a mesh system based only on the advertised "X,000 Mbps" number. With 50+ devices, capacity, backhaul quality, interference, and placement matter more than the theoretical maximum speed.
If the house has concrete floors or thick reinforced walls, I'd strongly prioritize Ethernet backhaul. Wireless mesh can work, but those structures can significantly weaken the connection between floors.
Bottom line: For this particular scenario, a 3-pack of TP-Link Deco BE65 with Ethernet backhaul is a sensible setup for a large, device-heavy home.
