Hey Breno,
sounds like the well known ad-hoc cell splitting problem to me. A common workaround is to fixate the BSSID to some pre-defined value:
iwconfig athX ap 02:CA:FF:EE:BA:BE
hopefully all your drivers support this. :)
best regards, Simon

Hello everyone,
I`m running several experiments involving ad hoc networks. I`ve selected some well known-to-be-compatible adapters, such as Edimax (Ralink shipset), Alfa networks (Realtek) and Atheros (madwifi). Atheros is available only as built-in adapter on the equipement or as a PCI board.
So, I'm experiencing some instability regarding the selection of the BSSID used by all the nodes. I start the network with a single node, then another, then another. Now, for a couple of minutes it works, bu then some nodes start losing sight of each and changing their BSSIDs to a different value (and they should always use the same). I'm really running out of explanations of why this is happening, because these nodes are all in-range of each other, and should be "pingable" directly. My main suspect is the driver instability, but then I dont know of any other better alternatives. I've tested the following USB adapters:
Edimax EW-7318USg (rt73 drivers)
Alfa AWUS036H-11g
And the builtin adapters:
Atheros chipset AR5007EG
best regards,
