WiFi signal strength in vista

[Maarten Weyn]

Is there a way to get the signal strength of all surroundin access points in
c# on a vista pc?

This should work for WinXP, but it does not work for vista.
thanks anyway

Doesn't work is of little help, what error do you get when you run this?

It runs fine for me under Vista, though the values for strength I get are
negative. I'm not sure what that indicates.

The value is the signal level, expressed in dBm, relative to the 1 milliWatt
(0dBm) energy level.
The lower the value the lower the signal level, -10dBm =
xcellent ------ -100dBm too low to be usable.

Thanks for the explanation. I wish I was at -10 then...

It gives a "not supported" at the line:
foreach ( ManagementObject mo in adapterObjects )

Two possibilities:
- the adapter is not a wireless type
- the adapter's NDIS driver is not WMI compliant.
