Wi-Fi load
Most flaky Wi-Fi smart home setups are really bad 2.4 GHz policy problems: band steering confusion, odd security settings, weak coverage, and channel congestion.
Best practices
- Use a dedicated 2.4 GHz IoT SSID if onboarding frequently fails.
- Prefer WPA2/WPA2-WPA3 mixed mode over forcing WPA3-only on cheap IoT gear.
- Use fixed non-overlapping channels where possible.
- Keep IoT devices on stable signal, not fringe coverage.
