Check the HCL for the PCI card.
Most likely you will have to set up with ndiswrapper.
Read through above. I picked the one above since you use Slack. I am not sure what your "friend" uses or what card.
If this is not correct for the card or disto.
Search here and google for "ndiswrapper <card model> <distro>"
Router setup should be the same as with any OS.
I hope this helps.
Use the HCL and the search here. They are one of the biggest assets this forum has.(sorry I am not preaching.)
