Internal wifi card
I opted for this model because of its low bracket, its brand and its wifi specifications.
When I unpacked it, I had to carefully remove two screws from the high bracket, remove the high bracket, position the low bracket, refasten the screws and insert the card into the SFF.
As most of the reviews were positive, I was tempted by this internal pci-express 1x card.
When the PC started up, it was directly recognised by Windows 10, so there was no need to install a driver.
If you decide to buy this internal wifi card, or any other device to be inserted into a PC, don't forget to discharge yourself of any static electricity so as not to damage the equipment.
