Link Info
- State
This field is used to display the current state of the driver. When the state is “Associated “ means
normal flow of operation in Infrastructure mode. The PC is connected to access point. BSSID is
shown in the form of hex digits. Networking is available.
A state of “Scanning ” means that the node is searching for available access point and cannot
detect the SSID for an access point within range.
This field will also display an error message if for some reason the driver failed to initialize.
- Rescan
Pressing the rescan button causes the driver to restart and begin its Connection Procedure. The
connection procedure differs depending on the Mode of the driver.
Infrastructure Mode - The driver will scan all available channels continuously until it finds one or
more Access Points that matches its SS ID. At that point it will try and authenticate and associate
with the Access Point.
802.11 Ad Hoc Mode - The driver will scan for 5 seconds looking for an existing 802.11Ad Hoc
network using the same SS ID. If one is not found the driver will start its own 802.11Ad Hoc network.
- Current Channel and Tx 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”
- Throughput
These two fields display the instantaneous wireless Receive and Transmit throughput displayed in
bytes per second. These values are updated every two seconds.
- 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 its Access Point. A label summarizes the
quality of the link over the bar graph, which can take on one of the following values:
“Poor”
“Weak”
“Fair”
“Good”
“Excellent”
