My friend has an old laptop that had XP on so I've installed Xubuntu 12.04 but when I tried to install the additional drivers for my USB wifi adaptor - a AVM Fritz with Broadcom 7xxx chipset (I dont remember the exact chipset) it crashed the laptop.
So what USB wifi adaptor do I need to buy that will definitely work with Xubuntu 12.04?
Im using Xubuntu 12.04 because its an old laptop and it has a none pea CPU (or some similar acronym) so it wont run Ubuntu 12 or the later versions of the other distros.
The USB adaptor I currently have isn't a new one, it is several years old. Is there a database anywhere listing what hardware works with Linux?
