Is it possible to take out a laptop WLAN card and connect it to the pc?
Theoretically yes. The only question is whether there are drivers on the PC or the WLAN card has a suitable connection point at all.
In theory, yes, that's possible.
In practice rather no. For particularly cheap notebooks, it happens that W-Lan is already firmly integrated on the motherboard and no extra card is. Of course it will not work then.
If in the notebook is a W-Lan card is removable, then most of the times has a mini PCI-Express connection and you need a riser adapter. The adapter then makes use mostly uneconomical.
Please note, however, that the cards will need an antenna which has been laid around the screen for the notebook. So that you then also receive W-Lan with the map, you must also have a suitable antenna for the map.
I would not do that because such wireless cards are not that powerful. For a PC, I would recommend this wireless card: https://www.caseking.de/gigabyte-wb1733d-i-wlan-bluetooth-5.0-adapter-pcie-802.11ac-zubt-006.html This is Dual Band WLAN and Bluetooth 5.0 on a card. You have to install the supplied driver CD. If you have no drive, in the included instructions is also a download link for the driver. I recommend this because it is always the newest. You should download it before installing.
I have this card too and I'm fully satisfied with it. I have 100 MBit over cable TV. When connecting via WLAN with the router, I only have about 5% loss.
For example, if you do not have a wireless card, you can just plug in a LAN cable
