Hi folks!

I'm trying to set up an access point under Linux, which will be provided
by an AR5418 Atheros PCI card. For testing, I also have the device
plugged in which will be in the client eventually. It is a D-Link USB WLAN
stick which uses the rt73usb driver.

Unfortunately, the devices can't even ping each other, although used, by
now, still without any encryption:
