TP-Link Deco Whole Home Mesh WiFi Router

Bottom line: The TP-Link Deco Whole Home Mesh WiFi Router: AC1200 dual-band: 300Mbps on 2.4GHz plus 867Mbps on 5GHz for 4K streaming; main trade-off: 1-pack is a single unit, so no mesh benefit until you buy a second Deco.

Pros & Cons

Pros

  • ✓ AC1200 dual-band: 300Mbps on 2.4GHz plus 867Mbps on 5GHz for 4K streaming
  • ✓ One unit covers up to 2,000 sq. ft.; add more Decos anytime to extend the mesh
  • ✓ Single network name with automatic device handoff between Deco units
  • ✓ Per-profile parental controls with online time limits and website blocking

Cons

  • ✗ 1-pack is a single unit, so no mesh benefit until you buy a second Deco
  • ✗ AC1200 WiFi 5 class, a step behind newer WiFi 6 and 6E mesh systems
  • ✗ 2.4GHz band tops out at 300Mbps, limiting older or distant devices
  • ✗ Dual-band only, so mesh traffic between units shares the client bands

Manufacturer description

The TP-Link Deco M4 is a mesh WiFi router for anyone whose single router leaves dead zones. One Deco M4 unit covers up to 2,000 sq. ft. If your home is bigger, you can add more Deco units later. They join a single mesh network with one network name, and your phone or laptop switches automatically to the nearest unit as you move around. The Deco M4 is an AC1200 dual-band router. It delivers up to 300Mbps on 2.4GHz and 867Mbps on 5GHz, which is enough to stream 4K with less buffering. MU-MIMO lets several devices run at high speed at the same time. Beamforming and IPv6 support are also built…
