Listmates,
I'm not sure where to start troubleshooting this problem. For months and months, ever since I installed Arch, my Atheros wifi (through ath0) has always just worked right out of the box. <snip> The mywpa.conf file is:
CONNECTION="wireless" INTERFACE=wlan0 SCAN="yes" SECURITY="wpa" ESSID="skyline" KEY="notmyrealkey" IP="dhcp" TIMEOUT=20
That profile would never have worked with ath0, as it specifies wlan0 as the interface.
Now I boot my box and I get nothing but the "lo" interface brought up. What gives? Check dmesg and/or your logs for clues. What in the world could have changed in the past week or so that is presenting my wireless from being brought up at boot?
As already mentioned - until you tell us what you have done to your system in the past week or so, you might as well be asking how to build one of these: http://en.wikipedia.org/wiki/Perpetual_motion T.
