Connectivity

The Connectivity webpage displays connections and available networks. The “Connected Devices” section displays the radio channel, received signal strength, and radio data rate for each Client or Access Point by their MAC Address. The readings shown are based upon the last received data message from the Access Point or Client. Client stations also display a list of detected Access points (Site Survey), including network name (SSID), channel and maximum data rate.

Note that when updating the Connectivity webpage, it is necessary to hold down the <ctrl> key while pressing the refresh button. Otherwise, the information will not be updated.

Connectivity Parameters

AID	Association ID: Every Client gets a unique temporary ID from the AP
CHAN	Channel: What radio channel is being used.
RATE	Radio Data Rate:
RSSI	Radio Signal Strength Index (Amount of received signal strength)
BGND	Background interference level in dBms: The amount of internal noise the radio is able to hear.
	This level does not indicate external radio interference noise level
CAPS	Capabilities (Ref 802.11 Standard)

Site Survey

Site Survey is a one off snapshot showing what Access Points are available for connection. This list is only available on Clients and only available at start-up of the module or by selecting Background Scanning on the radio page.

Site Survey
SSID	The Service Set Identifier or Network Name used to identify a particular network
BSSID	BSSID is the MAC (Medium Access Control) address of the AP (Access Point)
CHAN	Channel: What radio channel is being used
RATE	Maximum Radio Data Rate
S:N	Signal to Noise Ratio
INT	Beacon Interval
CAPS	Capabilities (Ref 802.11 Standard)
