How to choose
Read coverage as the maker's figure
Coverage figures come from the maker. The Deco S4 is rated for up to 5,500 sq ft by the maker, the Tenda ME6 Pro for up to 6,600 sq ft, and the eero for up to 1,500 sq ft. Walls, floors and placement change real coverage, so pick a figure above your home size rather than exactly matching it.
Compare packs, ports and device counts
Both the Deco S4 and the Tenda ME6 Pro come as 3-packs, while the eero comes as a 1-pack you can expand with cross-compatible hardware. The Deco S4 supports up to 100 devices and the Tenda ME6 Pro supports over 160 devices. For wired gear, the Tenda ME6 Pro adds 2.5 Gigabit Ethernet ports, while each Deco S4 has 2 Gigabit Ethernet ports.
Check Alexa control before you buy
All three picks work with Alexa in different ways. The Deco S4 turns guest WiFi on or off with Alexa voice commands, the Tenda ME6 Pro includes Amazon Alexa compatibility, and the eero manages network profiles with an Alexa device. Check which Alexa action you want, since a voice command for guest WiFi is not the same as profile management.
FAQ
Do all three systems work with Alexa?
Yes. The Deco S4 uses Alexa voice commands for guest WiFi, the Tenda ME6 Pro includes Amazon Alexa compatibility, and the eero works with an Alexa device to manage network profiles.
What does a mesh system change versus one router?
Mesh units work together as one network with a single network name, and devices switch between units as you move through your home.
Can I expand the eero system later?
Yes. The eero uses cross-compatible hardware, so you can add eero products as your needs change. Start with the 1-pack for up to 1,500 sq ft by the maker, then add units for more coverage.
