Ok, what Al is saying is true, but that's not the whole story. The product is essentially a PCIe x1 card that utilizes Intel's AX210 silicon and thus runs with Intel's Wireless and Bluetooth drivers. For all intents and purposes, issues occurring with this card are essentially the same as issues occurring with AX210 cards mounted on PCIe x1 card carriers.
So, let's look at this issue more closely. Address the possibilities in the order I talk about them (my diagnosis in each part is presuming this).
First of all, is the card mounted in a PCIe x1 slot? This is a requirement. There are known issues with the use of these types of cards (and card carriers in general) mounted in PCIe x4, x8 and x16 slots. Note that, because the Bluetooth portion is accessed via USB, it can work even in cases where the Wireless portion cannot.
If you wish to use this card in a system that had an older wireless solution, you need to look at doing one of two things. First of all, if this older wireless solution is a card mounted in a motherboard PCIe Half Mini or M.2 TypeA/TypeE connector, I would recommend removing it completely. If this is not possible, then I would look for a configuration parameter in BIOS Setup that disables this wireless solution during POST. If no such parameter is available, then I would disable the Wireless card in Windows Device Manager.
Ok, next, drivers. First of all, if the card does not appear in Device Manager, I would recommend completely uninstalling the Intel drivers that you have installed already. Once uninstalled completely, the card should show up as an unknown device in Device Manager. If this is not occurring, then there may be a hardware issue with it - and then your only recourse is contacting tp link regarding this failure.
Once you have the card appearing properly, I would first install the original versions of the Intel drivers that are provided on the tp link web site (aside: I recommend installing Bluetooth driver before Wireless driver). Once this is done, you should test that it is working properly. Only once it is working properly should you consider trying newer versions of the Intel drivers.
Hope this helps,
