• Hardware Radio Switch OFF: moving the hardware radio switch to the off
position has disabled the radio. Note that not all adapters have a hardware switch.
• Current Tx Rate: shows the current transmit rate of the current association.
• Current Channel: shows the channel on which the connection is made. In
Infrastructure mode, this number changes as the radio scans the available channels.
• Throughput: shows the short term transmit and receive throughput in
bytes/second, and is continuously updated.
• Link Quality: is based on the quality of the received signal of the Access Point
beacon.
• Signal Strength: is based on the received signal strength measurement of the
baseband processor of the Beacon signal.
You can click the Disable Radio button to turn off the wireless radio. When you
click this button, the State field indicates that the radio has been stopped and the
remaining fields in this window display either a zero or Not Applicable. Click this
button again to turn the radio back on. However, if the hardware switch on the
adapter has disabled the radio, clicking this button displays a popup message
telling you that the radio cannot be enabled.
You can click the Rescan button to force the radio to rescan all available channels.
If your link quality or signal strength is poor, rescanning can be used to push the
radio off a weak Access Point and search for a better link with another Access
Point.
