WMI: SSID, RSSI & MAC address

[Spartakus]

I have some problems getting valid/readable data from the WMI classes handling wireless network information. Here's what I got:

This the correct info I want:

     [color=Blue] public static void[/color] GetAvailableNetworks()
      {
      	[color=Blue]try[/color]
      	{
      	   [color=SeaGreen] /*Making the search*/[/color]
      		[color=Blue]string[/color] scope = [color=DarkRed]"root\\WMI"[/color];
      		[color=Blue]string[/color] query = [color=DarkRed]"SELECT * FROM MSNdis_80211_BSSIList"[/color];
      		[color=DeepSkyBlue]ManagementObjectSearcher[/color] mos = [color=Blue]new[/color] [color=DeepSkyBlue]ManagementObjectSearcher[/color](scope, query);
      		[color=DeepSkyBlue]ManagementObjectCollection[/color] moc = mos.Get();
      		[color=DeepSkyBlue]ManagementObjectCollection[/color].[color=DeepSkyBlue]ManagementObjectEnumerator[/color] moe = moc.GetEnumerator();
      		moe.MoveNext();
      		[color=SeaGreen]/*Adapter name*/[/color]
      		[color=DeepSkyBlue]Console[/color].WriteLine([color=DarkRed]"Adapter: "[/color] + moe.Current.Properties[[color=DarkRed]"InstanceName"[/color]].Value);
      		[color=SeaGreen]/*Number of available wireless networks*/[/color]
      		[color=DeepSkyBlue]Console[/color].WriteLine([color=DarkRed]"Available wireless networks: "[/color] + moe.Current.Properties[[color=DarkRed]"NumberOfItems"[/color]].Value);
      		[color=DeepSkyBlue]ManagementBaseObject[/color][] objarr = ([color=DeepSkyBlue]ManagementBaseObject[/color][]) moe.Current.Properties[[color=DarkRed]"Ndis80211BSSIList"[/color]].Value;
      
      		[color=Blue]foreach[/color] ([color=DeepSkyBlue]ManagementBaseObject[/color] queryObj [color=Blue]in[/color] objarr)
      		{
      			[color=SeaGreen]/*One SSID per line (SSID = name of nerwork)*/[/color]
      			[color=DeepSkyBlue]Console[/color].WriteLine([color=DeepSkyBlue]Encoding[/color].ASCII.GetChars(([color=Blue]byte[/color][])queryObj.Properties[[color=DarkRed]"Ndis80211Ssid"[/color]].Value));
      		   [color=SeaGreen]   /*
      			* Other info:
      			* Ndis80211Ssid (Service Set Identifer) (array of uint8) = byte[]
      			* Ndis80211MacAddress (array of uint8) = byte[]
      			* Ndis80211Rssi (Recieved Signal Strength Identifier) (uint32) (Must be converted to dBm :/)
      			*/[/color]
      		}
      	}
      	[color=Blue]catch[/color] ([color=DeepSkyBlue]ManagementException[/color] e)
      	{
      		[color=DeepSkyBlue]Console[/color].WriteLine([color=DarkRed]"An error occurred while querying for WMI data: "[/color] + e.Message);
      	}
      }

Is WMI ****ed up, or am I doing something wrong here?

About the RSSI, I know I can get it in dBm from "MSNdis_80211_RecievedSignalStrength" property, but that's ONLY for the CONNECTED accesspoint.

More trouble

Oh, great! Downloaded the latests drivers from Intel (80MB!), and to my pleasant suprise, WMI support was included So far, so good. Got connected to the wireless network again, and ran my little app above.

Turns out, WMI can't find an instance of "MSNdis_80211_BSSIList"


Tried to reinstall, deinstall and install with WMI, without WMI, reboot, etc, nothing worked....

Now I'm even off worse when than when I started...

Hello, Did you guys ever manage to find a solution to the problem? I'm finding BSSID_LIST is returning garbage after the first result as you did...

If you could let me know what you found out i'd be very grateful!
