When WLANs first appeared, operating systems were not equipped to be aware of their presence.Wireless NIC adapter manufacturers included client software utilities that were used to detect a wireless signal and then connect to that network.These client utilities also provided the ability to adjust client parameters, report statistics, and show signal strength.
However, the popularity of client utilities has decreased. Few wireless NIC adapter manufacturers now include client software utilities to accompany their hardware. In addition, some of those that do make the utilities available configure the software not to function unless that vendor's specific wireless NIC is installed and functioning in the computer.
