Signal History

Recommendations

Signal Strength Analysis

Your current signal strength is -65 dBm, which is considered good. For optimal performance, a signal strength of -67 dBm or better is recommended.

Channel Congestion

Your WiFi network is on channel 6, which has moderate congestion in your area. Consider switching to channel 1 or 11 for potentially better performance.

Placement Suggestion

Based on your signal pattern, moving your router to a more central location could improve coverage throughout your space.

Understanding WiFi Signal Strength

Learn how signal strength affects your WiFi performance and how to interpret the measurements

WiFi signal strength is measured in dBm (decibels relative to a milliwatt) and typically ranges from -30 dBm (excellent) to -90 dBm (very poor). Our analyzer helps you understand your signal quality and provides recommendations for improvement.

Signal Strength Ratings

Essential Knowledge
  • -30 to -50 dBm: Excellent signal (Maximum strength)
  • -50 to -60 dBm: Very good signal (Reliable connection)
  • -60 to -70 dBm: Good signal (Suitable for most applications)
  • -70 to -80 dBm: Fair signal (Minimum for reliable packet delivery)
  • -80 to -90 dBm: Poor signal (Unreliable connection)
  • Below -90 dBm: Very poor signal (No connection likely)

WiFi Channels

Performance Factor

WiFi networks operate on specific channels within the 2.4 GHz and 5 GHz frequency bands. Channel congestion occurs when multiple networks use the same channel in close proximity.

For 2.4 GHz networks, channels 1, 6, and 11 are recommended as they don't overlap with each other. For 5 GHz networks, there are many more non-overlapping channels available.

Signal-to-Noise Ratio

Technical Metric

The Signal-to-Noise Ratio (SNR) is the difference between your signal strength and the background noise level. A higher SNR means a cleaner signal and better connection quality.

For example, if your signal strength is -65 dBm and the noise level is -95 dBm, your SNR is 30 dB, which is excellent. An SNR of at least 20 dB is recommended for good performance.

Tips for Improving Signal Strength

Practical solutions to enhance your WiFi signal and network performance

Optimal Router Placement

High Impact

Position your router in a central location, elevated off the floor, and away from walls and metal objects. The ideal placement is in the center of your home at a height of 5-7 feet.

Reduce Interference

Quick Fix

Keep your router away from other electronic devices, especially microwave ovens, cordless phones, and Bluetooth devices. These can all cause signal interference and degrade your WiFi performance.

Update Router Firmware

Maintenance

Ensure your router is running the latest firmware for optimal performance and security. Manufacturers regularly release updates that can improve signal strength and fix bugs.

Upgrade Your Equipment

Investment

Consider upgrading to a newer router with better range and features if your current one is outdated. Modern routers with technologies like WiFi 6 offer significantly better performance and coverage.

Use WiFi Extenders or Mesh Systems

Coverage Solution

For larger spaces, consider using WiFi extenders or a mesh network system to expand coverage. Mesh systems are particularly effective for eliminating dead zones in multi-story homes.
