Physically removed the wifi card? I can't remember the last machine that had a pci card slot! Or is it some internal stuff? I am using a usb dongle on my Thinkpad X220 though...
It's an internal pci wifi card. It's a smaller form factor than an external pci card. Here's a link to a photo if you've never seen one. https://www.wirelesshack.org/wp-content/uploads/2015/09/How-To-Install-Upgrade-Your-Laptop-to-Wireless-802.11ac.jpg
