Status
This field is used to display the current status of connection. When the state shows “Connected to
SSID“ means normal flow of operation in Infrastructure mode. The PC is connected to access
point. Networking is available.
A state of “Scanning” means that the node is searching for available access point and unable
detects the SSID for an available access point within range.
This field will also display an error message for some reason if the driver failed to initialize.
Network Type
Infrastructure
Mode - The driver will scan all available channels continuously until it finds one or
more Access Points that matches its SSID. At that point it will try and authenticate and
associate with the Access Point.
Ad Hoc
Mode - The driver will scan for 5 seconds looking for an existing Ad Hoc network
using the same SSID.
-
Current Channel and Transmit Rate
Shows the channel of the radio and transmit rate are being currently used for an active connection.
This value has no meaning when the radio is “Scanning”
-
Link Quality
The Link Quality bar graph is only active when the node is in Infrastructure Mode. The bar graph
displays the quality of the link between the node and Access Point. It summarizes the quality of
the link over the bar graph, which can take on one of the following values:
“Poor”
“Fair”
“Good”
“Very Good”
“Excellent”
-
Signal Strength
The Signal Strength bar graph is only active when the node is in Infrastructure Mode. The bar
graph displays normalized signal strength as reported by the radio, averaged over all frames over
100 bytes long that are received from the Access Point.
