 graph_info This plugin shows the RSSI (Received Signal Strength Indication) as reported by the Access Point (AP) driver. The plugin is specific to broadcom wireless chipsets such as used on WRT hardware. We're not <em>quite</em> sure about the units the RSSI is measured in as this is not documented. Both dB and dBm are apparently candidates.  Higher is better.
