Somebody in the thread at some point said:

| Switch the wlan interface of Freerunner into master mode failed:
| iwconfig eth0 mode master
| Error for wireless request "Set Mode" (8B06) :
|    SET failed on device eth0 ; Invalid argument.

I don't think the firmware in the WLAN device has Master mode supported.

| "iwconfig eth0 mode ad-hoc" do not throw any error message but do not
work:
| iwconfig eth0 channel 1
| iwconfig eth0
| eth0      AR6000 802.11g  ESSID:"moko"          Mode:Ad-Hoc  Bit Rate:11

| there are no frequency set. And the openmoke is not able to connect to
| the other ad-hoc station. I have another wlan station in promiscuous
| mode with airodump output. And this station do not report any packet
| from the phone. Just the other station is detected.

Doesn't sound great... maybe try fiddling with ordering of setting
channel, also ifconfig up on it.  IIRC someone else reported luck with
Ad-Hoc.
