Hi everyone,

I'm trying to set up a wireless ad-hoc network between two colibri boards (pxa270 arm processor) running linux 2.6.12.4. To do so, I'm using two DWL-G122verC1 USB dongles and the rt73 wireless driver which can be downloaded on the Ralink website.

The problem is that I can't have my two linux boards ping each other (100% packet loss) even though I believe everything else is set properly. They are using the same channel (1) and there is no firewall issue.

Any ideas? I'm really stuck here :)

Thanks,

whose mac address is the cell? "D6:AA:43:D0:26:D6"

Actually, I think that the Cell value does not correspond to a MAC addres in the case of ad-hoc networking (It's not the address of an AP). Instead, the BSSID is the identifying name of the ad-hoc wireless network, I think it is randomly generated?
