Signal Strength, Visual Basic.net, Ndis80211ReceivedSignalStrength, WMI, No istances available
Posted on 2004-09-17
I'm testing the solution "Visual Basic, WMI and WiFi Signal Strength" asked by Jenn3 and solved by Mikal613.
I have an Intel(R) Pro/Wireless LAN PC Card and Windows 2000. The card is working correctly.
Running the solutions, and using a break point to intercept the cycle, I've noted it never stop inside the loop.
It exit the "For .. next" cycle without executing the instructions inside.
No errors are reported.
After this test, I've checked the WMI CIM Studio, and I've noted that "MSNdis80211ReceivedSignalStrength" istance is not available.
To be sure that the PC Card work correctly I've done two test:
1. The intel PROSet II PC Card manager report the signal strength correctly
2. The WMI CIM Studio istances correctly the MSNdisLinkSpeed, it list the right device number and, double-cliccking on the "Intel(R) Pro/Wireless LAN PC Card" link, it correctly shows the speed.
Note that I've installed all the PC Card'drivers including the *.mof files to update WMI.
