Airport doesn't pick up wifi after hard drive switch.
I used this guide to replace my hard drive (which works great btw), but somehow in the process I messed up my airport card. If the iMac is right next to the router it will pick it up, but move it to the next room and it see's nothing, even though my laptop gets full bars.
This makes me think I unplugged the antenna for it (does it even have one?), but going back through the guide I didn't see it mentioned. Also, I'm not sure if it matters but I was never able to get the front bezel latch to close correctly when I put it all back together.
