@strzmiele probably because it's an old mb

@Crenshawdk 

were there any changes in PCIE specification ? Maybe some mobo restrictions...I dont't know....I thougt always if there is free PCIE slot there shouldn't be any restriction to put there any PCIE device..It doesn't make sense to me ...I can't use a slot if another one is already used...

Anyone got better suggestions?

I've got the B450 aorus elite with updated BIOS and the latest Intel drivers and all the recommendations here. On some days when I turn on my PC it just doesn't detect the card. I have to reboot a couple of times before it shows up every couple of days. 

Is the TPLink TX3000E really just a piece of junk?

To all:

the error is not a TP Link issue.  I have a three months old PC.  I have the TP Link card, but before I bought it, I had a uBit card that also had Bluetooth.  In studying these two cards, they are both built on the Intel AX200 chip.  Aye, the uBit and TP-Link are one and the same, just branded differently.

Both cards react the same way on my PC.  Sometimes the card is recognised when I power it on, sometimes or more often, it's not.  I simply need to power off, wait about 2 minutes and power it back up.  Then all is well.

There is some process that involves the driver that does not load properly.  Both MS and Intel has no clue.

I continue to look at Task Manager, Task Scheduler, Process Explorer and Powershell "Get" to see any differences when it does load and when it doesn't.  So far nothing.

I honestly think this is a matter of the driver and Windows not being overly compatible. 

Eventually, Intel will rectify the issue.  If your issue is worse and not rectified by a simply power-down - wait - power-up, then perhaps separate PCIe cards for BT and WLAN is the best solution.

I had a frustrating and very upsetting experience.
I am using wifi card AX3000 Dual Band PCI-E WiFi 6 (802.11ax), Main GA-AX370-Gaming 3 (rev. 1.x) and Win 10. I tried all the ways you suggested but it doesn't work little. As the picture shows, I can't see wifi or bluetooth at all even though I have the latest bios driver and the latest card driver installed. I found out that every time I uninstall the network card driver and reinstall it a few times I see the wifi again but when I shutdow a few times it disappears. I can't understand how such a bad product without a warning to the user causes us to still buy and experience this annoyance. And in such a long time since the topic was created, the engineers have not made any improvements to the device driver???

@DungNQ get a refund.

They refunded mine. 

Hi , I just bought this pcie wifi adapter and have the same issues as you all, It was detected for a while but then after rebooting it will disappear, other than that I also experiencing several BSOD. My machine :

Aorus b450 pro wifi

AMD Ryzen 5 3600

GTX 1650 super 

Corsair vengeance 8x2 3200Mhz cl16

and Im running a latest windows 10, is there any permanent fix for this issue?

@Paris_lly as of yet no.  I still shut down, wait about 1 min, then boot back up.  On the rare ocassion, the wifi will be fine on the initial boot.  Although there have been several driver updates over the past few months and Win10 updates, to date, nothing has fixed this.

Try unplug PC for 10 seconds, plug back in. Helps some people.

While waiting for the engineers to find a way, I found a temporary fix although it was a bit annoying. The first time when I turn on the computer there is no Wifi icon but if I go to Network reset and press reset then I shut down (Note restart nothing happens) the computer and turn it back on with the button power will show both wifi and bluetooth. And now I restart comfortably and still don't lose wifi, only when I shut down the machine it loses again and I have to do the Network reset step again if I want to have wifi again. I still have not found a way to completely fix this problem, but I hope someone will find a way. I have to go to device manager to do view/show hidden devices, I will see the Intel(R) Wi-Fi 6 AX200 160MHz wifi card is hidden and press and properties will see the error line "Currently, this hardware devices is not connected to the computer (Code 45)"
