1) Windows Utility
Execute the released windows utility installer.
(1) Run RaUI.exe
(2) RaUI can co-exist with WZC. When coexisting with WZC,
RaUI only provides monitoring functions, such as surveying
the link status, network status, static counters,
advanced features status, WMM status and WPS status.
(3) When starting RaUI, the system will connect to the AP with best
signal strength without setting a profile or matching
a profile setting. It will issue a scan command to a wireless NIC.
After two seconds, the AP list will be updated with the results
of a BSS list scan.
