• Optimize Channel Selection (If Available/Necessary): While Deco systems typically manage channels automatically, in environments with significant wireless interference from neighboring networks, manually checking or allowing the system to re-scan for less congested channels can improve performance. Some advanced Deco models or firmware versions might offer more granular control over WiFi channels.
• Review Connected Devices: Periodically review the list of connected devices in the Deco app. Remove or block any unrecognized or unauthorized devices to prevent unauthorized access and conserve bandwidth. This also helps identify forgotten devices that might be consuming resources.
• Power Cycle Periodically: While not strictly necessary for all users, a periodic power cycle (unplugging and replugging) of your main Deco unit and modem (e.g., once a month) can refresh network connections and clear out any accumulated data or minor software glitches, similar to restarting a computer.
• Environmental Considerations: Ensure Deco units are in well-ventilated areas and not covered, as overheating can degrade performance and lifespan. Keep them free from dust accumulation. Avoid placing them near large metal objects or strong electromagnetic sources.
• Strong Network Security: Regularly update your WiFi password to a strong, unique phrase. Utilize the built-in HomeShield (or similar security features on your Deco model) for real-time network protection, intrusion prevention, and malicious content filtering. This protects your network from external threats that could impact performance or compromise data.
