Wireless Signal Strength

[Rafael]

It show your signal strength from your wireless network card.

How it works?

$dll(Wireless,1,,)

Return the signal strength in dBm.

For example, in my PC:

-53

Thanks for this plugin, Rafael! I recently started to use wireless networking and sometimes have problems with signal strength, so this lets me easily keep an eye on the signal.

I notice that you've used "Wireless" (capital W) rather than "wireless". Most of the other plugins use all lower case letters for their name. You must use "$dll(Wireless,1,,)" not "$dll(wireless,1,,)" like I tried first and got the "No Bridge Func" error.

How about seeing if you can also get the connection speed? Function 2 could return "54", "11" etc for the speed in Mbps.

Matt.

Hi Matt...

Sorry, at next time, I will take care of this case...

About the connection speed, I can?t, yet, read PDH counters in C#...

So you can obtain this values directly from your WNIC card using PDH counters!! You can check this speed in perfmon.exe utility.

Add a counter, select (in my case: Interface de Rede, in your, must be: Network Adapter), and select you WNIC...

Okay?

This is a great plugin. Any ideas on how to convert it to bars? First we'd have to deal with the negative number... is there a way to do math like absolute value or subtraction? Plus the closer to zero the higher the SS, correct?

Would you be willing to share your source code with us maybe?

Hi!

This is a very old project! If I found the source, I can put it here.

[Rafael]

private DateTime baseUTC = DateTime.UtcNow;


public string function1(string param1, string param2)
{
return Sinal();
}

public int GetMinRefreshInterval()
{
return 300;
}

private string Sinal()
{
string str1 = "root\\WMI";
string str2 = "select Ndis80211ReceivedSignalStrength from MSNdis_80211_ReceivedSignalStrength where active = true";
string str3 = "";
ManagementObjectCollection.ManagementObjectEnumerator managementObjectCollection_ManagementObjectEnumerator = new ManagementObjectSearcher(str1, str2).Get().GetEnumerator();
try
{
bool flag = managementObjectCollection_ManagementObjectEnumerator.MoveNext();
if (flag)
{
str3 = ((ManagementObject)managementObjectCollection_ManagementObjectEnumerator.Current)["Ndis80211ReceivedSignalStrength"].ToString();
break;
}
}
finally
{
bool flag = managementObjectCollection_ManagementObjectEnumerator == null;
if (!flag)
{
((IDisposable)managementObjectCollection_ManagementObjectEnumerator).Dispose();
}
}
return str3;
}
}

Can somebody upload the DLL file? Because the page doesent exist.

And if somebody knows how to put the result in percentage and in bars, i would appreciate!

Thanks!

I've edited the first post and attached the Wireless Signal Strength plugin dll that I got in 2006 from Rafael's site.
