For gaming, consistency beats peak speed. You can have fast internet and still suffer from jitter, bufferbloat, and Wi-Fi interference. This checklist focuses on changes that reduce lag spikes and improve stability.
1) Measure the right thing
Run a simple test during the times you actually play. Look for ping stability and jitter, not just download speed. A single test is not enough; repeat and compare.
2) Fix Wi-Fi basics first
- Place the router higher and more central, away from walls and metal.
- Use 5 GHz or 6 GHz when possible for less congestion.
- Avoid crowded channels; let the router auto-select if it does it well.
- Keep the console or PC within a clean line of sight if possible.
3) Prefer Ethernet for competitive play
Ethernet removes most interference variables. Even a long cable can be worth it if you care about stable input timing.
4) Deal with bufferbloat
Lag spikes often happen when someone in the house uploads photos or starts a stream. Smart queue management or basic QoS can help, but it must be configured carefully to avoid making things worse.
5) Avoid VPNs while gaming unless you have a specific reason
A VPN adds routing complexity. In rare cases it can improve routing, but often it adds latency. If you use one, test both ways.
