Signal to Noise Ratio (SNR) statistics can help you determine whether the interference is being created by too much noise on a channel. Receive Signal Strength (RSSI) statistics can indicate whether a low signal strength is creating the user’s performance problem. Operational rate statistics display the throughput per second. The following throughput rates are optimum:

„802.11b–11 Mb/s (optimum)

„802.11g/a–36 Mb/s or higher
