Which and How to Patch my driver for aircrack-ng

[Zer0id]

First if all, hi, I'm a new newbi.

So I need to know which correct "Patch" I need to install for my drivers in order to make aircrack-work properly. I don't know how to, so if you can tell me which commands I need to use, thanks.
Oh and, before everything I need to know how to backup my source prior applying patches in case something goes wrong and how to "recover" from it.

This is some information:

Support for aircrack-ng is not allowed on the Forums.

Although we have no reason at all to think you might be, we know that some people use aircrack for nefarious purposes and we don't want to provide a resource for them here.
