What is good wifi signal strength(RSSI)?

Good Wi-Fi signal strength is measured using the Received Signal Strength Indicator (RSSI), which typically ranges between -30 dBm (excellent) to -100 dBm (very poor). 

 

Here's a general breakdown of what different RSSI values mean:

• -30 dBm to -50 dBm: Excellent – The signal strength is very strong, typically right near the router. This is ideal for smooth, fast performance.
• -50 dBm to -60 dBm: Good – The signal strength is still strong, and you should experience good performance without any issues.
• -60 dBm to -70 dBm: Fair – The signal strength is adequate but starting to weaken. You may notice slower speeds or slight interruptions, especially with more bandwidth-intensive tasks.
• -70 dBm to -80 dBm: Poor – The signal is weak. Connectivity might still be possible, but it could be unreliable, with frequent disconnects or slow speeds.
• -80 dBm to -90 dBm: Very poor – At this level, the connection is likely very unstable or unusable.
• Below -90 dBm: No usable signal – The signal is too weak for any meaningful connection.

In general, an RSSI value of -60 dBm or better is considered good for reliable performance with minimal interruptions.
