Is there a sensor to monitor the signal strength of the WiFi card/adapter?

It seems like such a sensor is part of the mobile probe as described here: https://www.paessler.com/blog/2013/11/20/prtg/help-us-beta-test-our-new-mobile-probes

We're looking to monitor the WiFi signal strength on several PCs on which we've installed a remote probe.

Any help on how to accomplish that is greatly appreciated.

It looks like this information is available through WMI which means you would be able to query this with a Powershell script then format it to show the values in PRTG. You can see how to format this under Setup->PRTG API->Custom Sensors

I've reviewed the link you've provided;

That script seems to ouput the signal strenght in "bars", just like the number of bars you'd see for example on your cell phone or your computer.

What we're looking to obtain is the actual "dbm" value, exactly like the WIFI Signal sensor of the PRTG mobile probe does.

Any suggestion on how to retrieve that info is certainly appreciated.

If I'm not mistaken, you could just use the original output since that seems to be in dBm and just present that into PRTG. It would actually make the script much simpler since you wouldn't have to convert the signal strength and could put the result into a simple EXE result. Please mind that not all Wifi adapter manufacturers make it so that the drivers report this information to WMI and it's possible that you could get no result from the Machine's WMI system.
