Operational rate statistics display throughput per second.<br />

The following throughput rates are optimum:<br />

❑ 802.11b — 11 Mb/s (optimum)<br />

❑ 802.11g/a — 36 Mb/s or higher<br />

Signal to Noise Ratio (SNR) statistics can help you determine whether the interference<br />

is being created by too much noise on a channel. Receive Signal Strength (RSSI)<br />

statistics can indicate whether a low signal strength is creating the user’s performance<br />

problem. A high number of Transmit Timeouts (tx-timeouts) can indicate interference<br />

problems.<br />
