Wi-Fi works near the router but not upstairs

A location-specific failure is a coverage or interference problem, not an internet-account outage. Measure signal and performance at the router, stairwell and failed room before buying hardware.

Direct answer

A location-specific failure is a coverage or interference problem, not an internet-account outage. Measure signal and performance at the router, stairwell and failed room before buying hardware.

What this covers

  • The observed symptom matches this record
  • Customer-accessible settings, connections and external components
  • Diagnosis before reset, deletion or component replacement

What it does not cover

  • ×A model-specific error code with a different documented meaning
  • ×Internal electrical, battery-cell, gas, refrigeration or sealed-component repair
  • ×A guarantee that every model exposes the same control label

  1. Capture the exact symptom

    Reversible

    Run the same test device and service in three locations and note whether the network name disappears or stays connected without data.

  2. Run the smallest isolation test

    Reversible

    Move the router high and open, change orientation/placement, and compare 2.4 GHz with 5 GHz using the same device.

  3. Correct only the proven cause

    Reversible

    Keep the band/placement that reaches the room or add a wired/mesh access point where the backhaul remains strong.

  4. Verify before changing anything else

    Reversible

    Repeat download, upload and video-call tests in the failed room at busy time.

eero's path for a location-specific failure rather than a whole-network outage — placement, enclosed spaces, walls, interference.

Exact questions

Common follow-ups

What should I check before resetting anything?+

Run the same test device and service in three locations and note whether the network name disappears or stays connected without data.

What is the safest isolation test?+

Move the router high and open, change orientation/placement, and compare 2.4 GHz with 5 GHz using the same device.
