Hi guys.
So, I keep having more than usual problems with wifi. Anyway, very often, my wifi is running normally, but then, I turn the laptop of (shutdown), and unplug the power chord, and when i turn the laptop on in the morning, the wifi card is non-existent. The system doesn’t recognize it + wifi on/off hotkeys (fn+hotkey keyboard shortcut), are pretty much the only ones that don’t work. The volume & brightness ones do. When the wifi card is in such state (as in off, not recognized, whatever), not even lspci can recognize it, otherwise it finds it. It just projects it ‘dead’, as if it’s not in at all. Now, this problem was a really big pest on pre 3.2 kernels, and i haven’t had this issue often until recently, so i don’t know what’s causing it, because my wifi card should be supported with the ath5k driver. Anyway, here’s my hardware info:

Now, is there any way to analyze the situation when the wifi card is dead?
And i forgot to add - to make the wifi card work (for the system to turn it on) i have to do a hard reset, and pulling the power chord and battery out of the laptop, while it’s off. If i fail to do any of those two, the system doesn’t boot the wifi card.
Thanks in advance for all your tips.
