So if you have a PCI TP LINK wireless network card and you can’t find the driver, here is what you can do.
From device manager, right click on your wireless network card and update driver, pick the second option that is saying that you will locate manually the driver.
From the next window, pick the bottom option (not search recommended or browse for the folder).
The next window should display that it is possible to update the driver from Windows. You won’t have to insert the Windows cd in order to update, it should just work like that.
However, if that doesn’t work, just open the PC case and read on your tp link network card the model name. And then just google it and download the driver.
