Hi Kevin,

The specs of the system I've got problems with installing this card is the a120 from redux,

you can find full sepcs here: https://reduxgaming.nl/gaming-pc/redux-gamer-premium-a120/

The page is in Dutch, but if you you to specs, the images should explain all the specs in detail.

Important specs: 

Mobo: Gigabyte B450M DS3H

CPU: AMD 3600

GPU: RTX2060

PSU: 600W Silentium

Things I've tried besides the solution mentioned before:

1) I downloaded the Intel driver and support assistant, card was not detected.

2) Under device manager, showed hidden devices, the card showed up there, but gave error 35 (device not detected), tried to right-click + Detect hardware changes.

3) Uninstalled the driver from point 2, then tried re-detecting, & Manually installed the driver again

4) As the case does not allow me to put the GPU and WIFi card in to each others pci-e slots, I've turned off the system, then took the GPU out, and plugged the card into that x16 slot. Then rebooted the system, waited 10 min, then pressed the power button once. Re seated the card in the original pciex16 (x4 speed) still didn't solve the issue

5) checked the bios ERP was off, left it disabled.

6) Disabled fast boot in windows, disabled power saving options to put usb and PCIE to sleep & maximum performance for wifi.

7) Upodated the bios to F61(Available atm)

 On my Gigabyte gaming 7 x470 board it works fine ( the prebuild from Redux was for a friend, the wifi card they needed was recommended by me, as I've used it in the past for another build just fine as well) ( I was troubleshooting with myself and 2 more people for a good 2.5 hours before giving up and taking it with me, we had an internet connection on the host via usb tethering of my phone)

Hello, thank you for your valuable feedback. 

For TX50E hardware not detected problem, please try a PCIEx1 Slot / PCIEx4 slot and see if this helps ( photo attached for Gigabyte B450M DSH)

If still the same problem, can you share with us a photo of the Unknown device under Hidden device and Error Code?  if you unplug TX50E adapter does the unknown device disappear? Thank you. 

FYI, for now the latest Intel driver is 22.40:

I have the same problems on my b450 aoros elite, tryed everything (mentioned in this topic) and the card never works the first time I turn on the PC, I have to resset it several times until it works.

My system is Ryzen 7 2700, 32gb of ram, 2060 super in the aorus elite v1 b450

I manege to make it work but I have to turn the pc on, turn it off, and then turn on again (not reset)

then it works... but always have a pci e error in device manager
