@Whiplashing hola,  encontraste alguna solución? Tengo el mismo problema que vos y mi técnico de la PC me dijo que se supero el limite de uso de los puertos de la PC, que si quiero hacer funcionar la placa de Red tengo que ir por otra placa base como la Gigabyte B550 o similares o de gama más alta. La verdad no se que hacer. 

I've just had similar experiences to others here. Removing my old (cheap no-brand ebay card) and installing this, the device was not detected.

However, installing the old card alongside the TP-Link card allowed Windows 10 to search online automatically and the TP-Link card was recognised as Intel Wi-Fi 6 AX200 160mhz (which, apparently, is the correct identification). Afterwards, I shutdown, uninstalled the old card again and booting up again, everything appears to be working.

Presumably, if you can connect to your router via ethernet instead of an old wifi card, that would also work. The main point is having an internet connection when installing this card - which is a little counterintuitive!

Hope that helps someone...

I just wanted to share what did it for me. I have an old honker of a motherboard, an Asus Sabertooth z77 which might explain my troubles, but what did it for me was to set PCI Express X16_3 slot bandwidth to X1 mode in BIOS and presto the card was detected. Also it only seemed work for one of the PCIe 2.0 x1 slots Hope this helps.

I've put it into PCIE X4 Slot on my Gigabyte GA-Z77MX-D3h with Xeon Prozessor and the card doesn't work on my system I've got error Code 10...

Earlier I haven't any troubles with hardware compatibilities....this is the first case and as TP-Link wrote in specification "card is compatible with PCIE X1/X4/X8" ... I put card in the slot and try to install drivers ...what I iam doing wrong ? Maybe card has many compatibility problems ..

@Solla-topee 

Hallo, I've tried this driver yesterday but without success ...same Error (Code 10)

and as I wrote WIFI Card is placed in PCIE Slot described as PCIE X4 on MoBo:

@Solla-topee hola, en mi caso no funcionó actualizando el controlador intel más reciente, ya que mi sistema operativo directamente NO detecta la placa de Red, ni siquiera en la Bios figura el dispositivo en el puerto PCI.

Solo es reconocido en el sistema si coloco la placa de Red en el puerto PCIE con la PC encendida, la cual está mal por que puede generar un fallo en el sistema eléctrico. 

@strzmiele Thank you very much for your reply. To better assist you we'd like to follow up your case via email and may escalate your case, please check the email with title 【Forum ID 215446】, thank you~

Hola Jonathan

So the adapter is still not working. I doesn't make any sense what you pc-engineer is saying that you don't have enough pc acces points. Because the motherboard we have is allready pretty high end. So if you still have the receipt I'll recommend you to bring i back and get another one.

Short summary ...I got the card to work.

Why does the card not work in all PCIE slots (X1/X4/X8 in my case X8) ? Why card was detected and shown in device manager list with exclamation mark ? For both question I have no answer....
