eero mesh wifi troubleshooting

Published specification

What is true of this model and changes how you fix it

• Official specifications
  Tri-band (2.4GHz 2x2, 5GHz 4x4, 6GHz 4x4), up to 4.3Gbps wireless / 9.4Gbps wired. Four Ethernet ports (two 10 GbE, two 2.5 GbE). Covers up to 2,500 sq ft per device, 200+ supported devices — the top of eero's whole lineup on every spec.
• Wi-Fi 7 MESH (flagship, 10G ports)
  Amazon eero's flagship Wi-Fi 7 (BE) mesh with 2.4/5/6 GHz and 10 Gigabit ports. Units cover a large home; a weak room means a node is too far. Wi-Fi 7/6 GHz needs compatible clients.
• eero is app-only + auto-updates
  Eero is managed entirely through the eero app (there is NO web admin), and it auto-updates itself, so a lot of traditional router settings are simplified or automatic by design. TrueMesh routes traffic automatically between nodes.
• Mesh backhaul
  A node offline is usually power or a too-weak backhaul — place nodes within range or wire them (eero supports Ethernet backhaul, best for the Max 7's speed).
• The multi-gig gateway
  The eero Max 7 is eero's flagship Wi-Fi 7 router, designed for multi-gigabit fiber plans with two 10 Gigabit Ethernet ports. It runs from the eero app, and its main job is to be the fast gateway for the rest of an eero system.
• What owners run into
  Owners with multi-gig plans find that speeds are limited by the cable, the switch or the device and not by the Max 7; a link showing 1 Gigabit usually means a cable or a port. Setup behind a provider's box leads to double NAT.
• How to approach a fault
  Check link speeds in the app, swap a Cat6 or better cable and restart modem, then eero. Put the provider's box in bridge mode if the app reports double NAT.
• Finding your unit and its link speed
  The eero app shows each unit and its wired link speed. A 10 Gigabit port that shows 1 Gigabit points to a cable that cannot carry more, a switch or a device that does not support it. Use Cat6a or better for a 10 Gigabit link.
• Where it fits in a home
  As the gateway it connects to the modem or fiber box, and other eero units, including the Outdoor 7, connect to it. Place it near the center of the home if the modem allows, because the router also provides coverage.
• Double NAT
  If the provider's box also routes, the app reports double NAT. Put the provider's box in bridge mode or ask for a modem-only service, so the Max 7 gets the public address.
• Also covered
  eero Pro 6E, eero Pro 6E (from the Wikipedia company page): Released in March 2022 as an AX5400 Wi-Fi 6E mesh node with Ethernet ports, Thread and Matter support, covering about 2,000 sq ft.
• Also covered
  eero Pro 6E, compared with Pro 6: The Pro 6 is AX4200 without the 6 GHz band.
