SOLUTION HERE
Ok guys I found the solution !
I tried all the solution posted here, especially what said Aitese. Nothing worked.
You have to use Windows Update, plug your computer with an ethernet cable, do the update with your device plugged. You can unplug your ethernet cable. Done !
Try it and tell me. That works with my TL-WN722n and my Netgear device too.

Aitese, can you please post an exact url to this website you are talking about with regard to a "list of manufacturers". I can not find what it is you are talking about. I too need the Atheros chipset driver for my TL-WN951N v1 (64-bit Windows 8). Very much appreciated.

Since aitese will not be able to post a link because of his lack of the correct number of posts, I will attempt to do so for him. I believe this is the link to the model he has posted for.

If this is not the one, perhaps you can use this link to the web site then search from there. Best of luck.

In Windows 8 go to Search and find Device Manager. You should see your unknown network adapter with a yellow warning sign next to it.

Right click the device and select Update Driver Software... which will bring up a dialogue box. You'll have two options, you want to select Browse my computer for driver software.

Next you want to select the option Let me pick from a list of device drivers on my computer. Wait for the list of devices to load.

Now you will need another computer, smartphone or tablet with an Internet connection to do a search. In my case my specific TP-Link card was a TL-WN951N v1. You simply Google "<your specific model> chipset".

In my case the TL-WN951N has an Atheros chipset. In the list of manufacturers on the left scroll to Atheros Communications Inc. (or whichever chipset manufacturer provided the chipset for your specific card) and then on the right scroll down until you find the card you have, in my case and in the case of the provider of the screenshot above a TP-LINK Wireless N Adapter. Select this and hit Next.

This should successfully install the correct drivers.

This worked so good.. Thanks a million I was getting deperate but not to desperate to open my case as its well packed up and hidden lucky i had the exact same card as you. thanks champ

I joined this forum specially to thank you for this, I've been trying for a long time to get this working I even tried looking through list of devices but was trying to find it under brand name not the chipset. So THANK YOU VERY MUCH..

Yes, I have managed to fix the problem by using the solution provided above..

If you are still using Win 8 CP, perhaps a clean install of Win 8 RP would be in order. RP is the most recent beta version of Win 8.

Get driver from www.TP-link.com.cn

Hi

I had a driver problem with tp-link tl wn722n in windows 8. (solved myself but tried all the things on the internet)
The errors I got were:
Windows encountered a problem installing the driver software for your device
Windows found driver software for your device but encountered an error while attempting to install it.
The hash for the file is not present in the specified catalog file. The file is likely corrupt or the victim of tampering.

And, also when I try to install the software utilities on windows 8, i got blue screen and I fixed using refresing windows 8.
Then I tried lots of manual installation things, but only that one worked for me

go to www . tp-link . com/en/support/download/?model=TL-WN722N&version=V1 (you need to establish some other internet connection of course)
download TL-WN722N_100629
or direct download via this link www . tp-link . com/resources/software/TL-WN722N_100629.zip
extract zip file
run devmgmt.msc (device manager)
click on (or highlight with keyboard) USB2.0 WLAN
open context menu (right click or press context menu key)
click/hit enter on update driver software
select browse my computer
locate the folder you've got after extraction
next
you're done

I've tried so many things with the driver in the cd coming within package, none of them worked. (tried to install atheros chip driver, got same error)
I searched web and since win8 is new, there was no help form there. Tried described things in websites but none of them worked.
Now it's perfect.
I did restarted my windows 8 and didn't get BSOD. I'm very relaxed right now.

For hope of search engines:
windows 8 tp-link tl wn722n driver
windows 8 tp-link tl wn722n driver download
windows 8 tp-link tl wn722n driver installation problem
windows 8 tp-link tl wn722n driver problem
windows 8 tp-link tl wn722n driver hash
windows 8 tp-link tl wn722n driver corrupt
windows 8 tp-link tl wn722n driver victim
windows 8 tp-link tl wn722n driver BSOD

I noticed that connection gets lost after sleep. But it may be a general issue, I don't know.

Ii I don't know if anyone is still interested in drives for their TP-Link wireless adapters but the one I've been using with my Windows 8 TP-Link TL WN721N is actually from Atheros or Qualcomm. They have the drivers that I've been using since I got this new computer therefore Windows 8. I don't even remember how it is that I learned this but it works great.

If anyone still wonders about a driver that is.....
