Some NICs require a firmware blob. For example, for open-use and Wi-Fi cards on the b43 chip, you need to install a package that is not supplied in the distribution, but is supplied in a separate non-oss repository. Accordingly, we get the Internet in any way (phones on android via usb work well), we look for a package by the name of the chip in additional repositories (or download a package for our distribution kit from the site of the network card manufacturer), as a rule, we have a profit. If this method is not suitable, then the interesting begins, without qualification it is easier to follow the path of buying a compatible network card.
