Yes, good catch! I don't know what 'RUNNING' signifies.
BUT: I got it working yesterday night.
First, it might have been a firewall issue (on the MacBook side).
Second, after deactivating the Mac firewall, I tested various Channels (Frequencies, right?) and (Transmit Rates).
I have an Atheros Chipset (AR2413), and it seems the new in-kernel driver ath5k doesn't have support for all features and all rates, yet.
I got good results with 24M, which is almost half of what this card should be able to do, but hey.
Some notes on Ad-Hoc:
man iwconfig says about the display of Signal level, Noise level: "In Ad-Hoc mode, this may be undefined and you should use iwspy."
Well, my Card doesn't support iwspy, or the driver doesn't, but maybe it will work for you.
