So, I ripped apart my laptop to clean the gunk out of the heatsink fan and such. To do so, I had to remove the wireless card. After putting the machine back together, the wireless no longer works.
When typing the usual ifconfig wlan0 up, I get
SIOCSIFFLAGS: unknown error 132
After further tinkering, I booted from the install CD. ifconfig wlan0 up works there, but when I do iwlist wlan0 scan, I get no scan results.
I've tried fiddling with the wireless card, making sure it is connected, and it seems in order. I've also checked the leads on the antenna. Everything looks good. I also checked the button that turns the wireless on and off. It connects to the motherboard with the same set of wires that the main power switch is on, so I assume it's OK.
I've made no changes to my configuration. Previously I didn't need to load any extra kernel modules to have wifi working.
The laptop is a Compaq CQ50-215CA, with an atheros chipset, for your information.
Any idea what I fucked up?

What does "rfkill llist all" say?

You obviously need to put the gunk back in.

You may have fried the board with a static discharge. Did you wear a wrist band or at least keep discharging your hands by touching grounded metal while working with the components?

As for the grounding, I make a point to keep grounded, but you never know.

that means its not disabled hardware side, I guess. tried an "rfkill unblock all"?

Thanks, that worked. For the sake of others searching this topic, can someone explain what happened?

no idea, really... but I had similar troubles getting up the wifi, when it was little-button-press turned off and the laptop crashed. After some random combinations of blocking/unblocking with button and rfkill, it worked again.
all voodoo to me.
