I opened up my Mac Mini[0] to see if I could put in a longer range wireless antenna. I closed it back up, as the extended antenna wouldn't fit, but when I turned it on, the wireless didn't work. The wireless card has always worked before, as it is Atheros. I know it is not a hardware problem, as I am typing this running off of the Trisquel 6.0 Live CD, connected to the wireless network.

$ sudo lspci -v

Before I booted into the Live CD, I noticed that the last two lines indicating which driver is in use were not present.

Just a guess, but try

sudo modprobe ath5k

I get this: FATAL: Module ath5k not found.
On the Live CD, nothing shows up after entering that command.

Are you running a custom kernel?

uname -r

Yes, I was, (a vanilla Linux-libre 3.10) now I am booted into the 3.2.0-48-generic-pae kernel, and wireless works now.

I guess that 3.10 is compiled without the ath5k module. I believe it's possible to compile just one module to add to a kernel instead of the whole thing but I don't know how...

I wrote a little howto for the whole thing at https://trisquel.info/en/wiki/compiling-gnu-linux-libre-kernel

The strange part was that it stopped working after I opened up my Mac mini, so I first thought that I damaged the hardware inside.

That's how the mind works, fortunately it wasn't so.
