Hi,

Could you maybe post a screenshot of the Device Manager that shows the Wi-Fi card in different places than in the guides?

Once a driver is installed it should show up under "Network adapters" as "Intel(R) Wi-Fi 6E AX210 160MHz".

It's showing under "another device's" named something around PCIE slot. I can send picture after 5pm. Also when i trying to update this driver, always shows blue screen ^^

Ok.

It is normal for a Wi-Fi card to show up under "Other devices" as "Network controller" as long as there is no suitable driver installed.

However, it is unclear why the driver for the TXE75E doesn't install.

A driver installer will look if there is any hardware that matches one of the hardware IDs listed within the driver.

So, we should check what the hardware ID of that "Network controller" under "Other devices" is. To do that right-click on the "Network controller", choose "Properties", then the "Details" tab and then select "Hardware Ids" from the dropdown selection. Please post the Hardware ID here.

I check also this usb where I connect adapter. Previously there were LED lights plugged into it Since it is plugged in, this yellow triangle is constantly displayed in the device manager.

And now this when i turn off PC.. what just happen ^^ never have this before

Let's care about the Wi-Fi driver first.

The hardware IDs of your card look fine. There should be no reason for the driver to refuse installation.

Try to install the driver manually by downloading it from here

https://www.intel.com/content/www/us/en/download/18231/intel-proset-wireless-software-and-wi-fi-drivers-for-it-administrators.html

unzip it to a folder on your hard disk

and then right-click on the "Network controller", select "Update driver" and browse to the folder into which you unzipped the driver files. Then click "Next" and check what happens.

Ok, so I did it and now I can choose which Wi-Fi to connect to. I have a choice between Wi-Fi and Wi-Fi 3. When I turn on the new Wi-Fi 3, the download speed was for a 5 minut 1100 and now back to again 600... so it's looks like works exactly this same like orginal. How can I be sure it works?

Bluetooth also not working.

That's how is looks like now Device Manager. Network controller disappeared
