Different wlan cards

[unrulyj]

Hi so im overseas and left my computer at home, I’d like to buy a new wlan card online but i am seeing some with one opening to separate the pins and others with two. Is it possible to use any one regardless of the pci slot on the computer.

Thanks for replying in advance.

Are you talking about mini-pcie wlan cards? Is your pc - a laptop?

Interesting part:
although plugging a PCI Express card into a slot smaller than itself is not physically possible, plugging into a larger slot is mechanically possible. During training, the host device simply queries the device for its maximum link speed and assigns resources as needed.
