inSSIDer Office will give a Signal Strength Warning if it detects poor signal strength from the selected wireless network.
To achieve reliable connectivity and good WiFi speeds, the stronger the signal strength, the better. Below are some general rules-of-thumb regarding signal strength:
Note: The numbers in this chart are suggestions only. The desired signal strengths will vary, based on the requirements for the network.
| Signal Strength | Required for | |
| -30 dBm | Max achievable signal strength. The client can only be a few feet from the AP to achieve this. Not typical or desirable in the real world. | N/A |
| -67 dBm | Minimum signal strength for applications that require very reliable, timely packet delivery. | VoIP/VoWiFi, streaming video |
| -70 dBm | Minimum signal strength for reliable packet delivery. | Email, web |
| -80 dBm | Minimum signal strength for basic connectivity. Packet delivery may be unreliable. | N/A |
| -90 dBm | Approaching or drowning in the noise floor. Any functionality is highly unlikely. | N/A |
