WiFi problems usually look like random spikes. The connection is not consistently bad. It is inconsistent. Your goal is to reduce variance so timing stays predictable in real matches.

Why WiFi Gets Unstable

  • Interference from neighbors and devices.
  • Weak signal through walls and floors.
  • Busy airtime from multiple clients.
  • Poor placement causing retries and spikes.

Practical Fix Order

  1. Move closer or improve router placement (height and open space).
  2. Use a cleaner channel and reduce congestion.
  3. Separate devices by band if needed (keep gaming device on the cleaner band).
  4. Avoid background uploads during play.
  5. If spikes remain, switch to Ethernet for serious sessions.

How to Test (Simple)

  • Test during real household use, not at night when everything is quiet.
  • Look for spikes, not only averages.
  • Repeat the same scenario to compare changes.

The Rule

WiFi can be fast and still feel bad. Stability beats speed for gaming. Fix variance first.
