You may try API's MSNDIS, OID'S, and Managed [Wifi](https://www.mindstick.com/articles/23242/a-guide-to-test-your-wifi-and-make-it-3x-faster) Although the API and their signature haven’t changed (AFAIK), there are differences between WiFi on Win7 and XP so you may want to be careful using XP examples.\
\
A managed C# wrapper around WlanAPI that works on Win7 can be found here:http://managedwifi.codeplex.com/workitem/list/basic?size=2147483647.\
\
The WLAN_BSS_ENTRY structure has a lssi property. The documentation forWlanGetAvailableNetworkList has some C++ sample code which would probably be useful to read through first and then you can look at the PInvoke page for WlanGetAvailableNetworkList for a short C# sample.\
