Optimising connection through the hidden menu
The information revealed by the hidden Wi-Fi menu enables users to make targeted improvements to their wireless connectivity. By monitoring signal strength values, you can identify dead zones in your home or office and determine the best placement for your device when maximum performance is required.
Signal strength interpretation
Wi-Fi signal strength is measured in decibel-milliwatts (dBm) with values typically ranging from -30 dBm (excellent) to -90 dBm (very poor). Understanding these measurements helps you assess connection quality:
- -30 to -50 dBm: excellent signal with maximum performance
- -50 to -60 dBm: very good signal suitable for all activities
- -60 to -70 dBm: good signal adequate for most tasks
- -70 to -80 dBm: fair signal with potential performance limitations
- -80 to -90 dBm: weak signal requiring improvement
By monitoring these values whilst moving around your space, you can create a mental map of signal coverage and identify areas requiring Wi-Fi range extenders or mesh network nodes to improve coverage.
