2.4 GHz smart home best practices

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.

Next steps

• If the specific problem is a 2.4 GHz smart plug that will not connect, use the exact setup checklist
• If the plug may be bad hardware, use the broader smart-plug diagnosis page
