Why there is there “N/A” displayed for some of the statistical & status information?
Not all Wireless cards can display all statistical & status information. This is because some wireless adapter device drivers don’t fully support the Microsoft standard Network Driver Interface Specification (NDIS) for 802.11. In fact during our testing we found most cards only support a subset of the potential information. WirelessMon displays “N/A” when no information is provided by the device driver.
