I have just purchased the TP-Link WN951N wireless PCI card to upgrade from my old adapter and have encountered a problem when trying to install the driver. I have been to the TP-Link website and tried all of the availbe drivers that they have listed for Windows 7, I have also tried installing an Atheros driver as when I have been searching through Google I found that it uses an Atheros chipset.
The drivers that I have tried appear to install although I get a warning when first installing that it might not be compatible and the driver says that it is installed and working but I cannot see any wireless networks. When I click on the diagnose button it goes through it's process and then tells me that there is a driver problem still.
In the device manager it says that the device is working properly and in the Network Connections section if i double click on the icon it reports that it is connected at 412.3Gbps which is confusing in itself but when i click on the details tab to see the state of the connection both of the property and value tabs are blank
Also I have had no error codes that may help in the diagnosis so sorry about that :-(
I hope this is enough information for someone to at least suggest what may be the problem
