Hi,

If the automatic installer fails to run properly, then you can alternatively try to install the driver manually via Windows' Device Manager.

To do that go to Intel's driver download webpage and select "Intel® PROSet/Wireless Software and Drivers for IT Admins". From there download the correct *.zip file for your Windows version, then extract the downloaded *.zip file to a folder on your hard disk.

  @woozle Thanks for answering. Could you please provide a valid link for my TX55E adapter to download the .zip you are indicating? Thanks for your help.

Edit: I have found the link, I have downloaded the one compatible with my operating system (Windows 10 64 bits), I go to the device manager, I go to the unknown device (which is actually the TX55E) I try to install the driver from the folder that I have unzipped the .zip and it says: "Windows could not install your unknown device. Windows cannot find drivers for the device. If you know who made the device. Look for information about drivers to download from the Support section of the website. maker".

Beside this, if it's not too much of a hassle you could also bring your PC close enough to your Internet router and hook it up via Ethernet cable. Once Windows 10 has an Internet connection it should normally pull the newest drivers from Windows Update and install the drivers for this Wi-Fi card all by itself.

  @woozle I have edited my previous comment, apart from that, I am connected to the internet from the PLC, my equipment is a desktop, going to the router and connecting an RJ-45 cable is not an option... Although right now I have internet with the PLC. It's valid right?

Ok, I see.

It seems to me as if your TX55E is not detected properly. 

Can you please check from the Device Manager what is the hardware ID of that "unknown device"? (click "Properties" of the device, then the tab named something like "detailed information" and from the dropdown menu select hardware IDs.

I think your TX55E should be detected as either "PCI\VEN_8086&DEV_2723......" or "PCI\VEN_8086&DEV_2725......".

Hardware ID: root\LGHUBVirtualBus path to device instance: ROOT\SYSTEM\0001 Now I'm in doubt if that device is the TX55E... I'm going to remove it from the PCIE and reconnect it.

EDIT: It seems that the problem is that when screwing the item to the PC case (I don't know what the name of the metal part that is screwed into the computer case is called) it came loose, hence it didn't work, but it's strange because Bluetooth did have ... Anyway, I have removed it, I have put it back, but I can't put it with the screw to hold it to the computer case (PC), it is loose... Let's see if I can find a solution to that .

Yeah, sometimes PC cases are not of the greatest quality and then things don't fit nicely. I've had such issues before.

What you can try is to loosen the two screws that hold the slot cover in place. There is usually a bit of wiggle room available and if you are lucky it may be enough to make it fit better. Then tighten the screws again.
