WiFi is a reliable source for internet access and provides uninterrupted connectivity with good speed. However, you may sometimes notice slow page loading, fluctuating download and upload speeds, or weaker connections in certain areas of your home. This happens due to variations in WiFi signal strength across different locations.
Checking WiFi Signal Bars on Devices
For devices like smartphones and laptops, WiFi signal strength is usually represented by signal bars. The fewer the bars, the weaker the connection. You can walk around your home while connected to WiFi and observe the signal bars decreasing as you move farther from the router. While this is a simple way to check strength, it does not provide precise measurements.
Using WiFi Analyzer Apps
For a more accurate assessment, you can use WiFi analyzer apps. These apps provide numerical data on signal strength in dBm (decibels relative to a milliwatt), which ranges from -30 to -90. A reading of -30 indicates excellent signal strength, typically when you are very close to the router. A reading of -90 indicates the weakest possible signal, where connecting to the network might even fail.
Understanding Signal Strength Readings
Intermediate values, such as -50 to -60 dBm, are generally good for normal usage, including browsing and streaming. Values closer to -70 dBm or weaker may result in slower speeds and a degraded internet experience. Monitoring your WiFi signal strength can help you find the best spot in your home for optimal performance and ensure smooth connectivity.
