Slow or Unstable Wi-Fi: The Home Troubleshooting Guide

A finicky Wi-Fi ruins everything. Good news: 9 times out of 10, the cause is easy to identify.

Slow or unstable Wi-Fi: the home diagnostic guide

1. Place the box properly

In the center of the home, at a height, away from the microwave and thick walls. That already makes a big difference.

2. Test the speed

Compare near the box and then in the problematic room. A huge difference = a coverage issue, not a subscription problem.

3. The solutions

  • Change the Wi-Fi channel (less interference).
  • Switch to 5 GHz for speed, 2.4 GHz for range.
  • Add a repeater or a mesh system for large areas.

If your Wi-Fi is slow in one room but fast near the box, the signal isn’t reaching far enough. Moving the box, changing the channel, or adding a repeater can help spread the signal better.

In a 150m² apartment, a Wi-Fi box placed in a corner near a brick wall struggles to reach the far bedroom. Moving it to the center and switching to 5 GHz improves speed in the living room, while a mesh node in the bedroom ensures stable coverage everywhere.
