Debian – How to detect and install a Wifi adapter in Debian


I've recently imaged a laptop with a Debian 5.0, and it doesn't appear to be detecting the wifi adapter. The image was originally from a different laptop, so maybe this is part of the problem.

How do I install the drivers for the card? Furthermore, I'm not even sure what the adapter model is (all I know is that the previous Windows XP install used Intel wifi drivers), so is there a way to find out the chipset model number? Also to make matters worse, there's no model number on the case – other than "Phillips Freevents".

Best Answer

To know what driver to look for here is a simple way:

  • If the card is PCI, run lspci in a shell and look for the closest thing.
  • In case the card is USB, run lsusb.
