Recently bought a USB network adapter and i'm trying to set it up but my operating system doesn't seem to recognize the driver files.

The operating system is Windows 8.1
The network adapter the the TP-Link TL-WN722N

I thought the adapter was supposed to be plug and play so just plugged it in and waited for the light to come on showing it was on but nothing happened.

Then I inserted the CD that came with it into my laptop and ran the application.
I then clicked the install driver button.

The installation wizard popped up and asked if i wanted to install the TP-Link application thingy for connecting to wifi and the driver or just the driver.

I selected the just the driver.

I waited till it had finished installing and then removed the adapter and turned the computer off.

Once the computer was turned back on I then plugged the adapter back in.

The light still on the adapter wasn't on so I opened windows device manager.

In the network adapter section were two Realtek entry's that I think are for my laptops built in wireless card one was called the GBE Family Controller.

I think they are the drivers for my built in card because when i disable them there is a DNS_PROBE_FINISHED_NO_INTERNET error when browsing with Google Chrome.

In the section Other devices there is a device called 802. 11n NIC which has the following status:

The drivers for this device are not installed. (Code 28)
There are no compatible drivers for this device.
To find a driver for this device, click Update Driver.
Manufacturer: Unknown.
Location: Port_#0003.Hub_#0001

I believe this device to be the TP wireless adapter because the device disappears when I remove the adapter and reappears when I insert it back in.

I tried updating it using the driver I had installed on my laptop from the CD but Windows said it couldn't find the driver software for the device when i told it to browse in the directory it was in and when i told windows to search automatically for updated software.

I then repeated this with the driver files online from the TP-Link site after downloading and unzipping them with 7zip.

I got the same results.

Then I looked at an online forum and went onto the Microsoft easy fix solutions for find and fix problems with devices and hardware and ran the program which said problem 802. 11n NIC doesn't have a driver with a status of not fixed and problem: hardware changes might not be detected status detected.
I also checked for Windows OS updates but was fully up to date

Thats as far as i got no idea of where to go from here. Seems that either there is a problem with my operating system not being able to detect the unzipped driver files or the driver files both on the disc and both versions from online are so faulty they aren't even recognized as drivers. There is also the problem that the device itself wasn't even recognized with a name that's identifiable which means there must be a problem in communication between the device and the operating system. Would trying a driver from the chipset manufacturer help at all? Please & Thank You
