I think this is incorrect. The APs don't negotiate anything among them.

I am not sure of what you mean by 'routing', since an AP is a layer 2 device and routing is layer 3. If I understand correctly your question, you want to know with which AP the client will associate. It depends on the configuration of the APs and the client. If the APs have different SSIDs, and the client is set to the zero-lenght SSID (incorrectly referred to as the "ANY" SSID), then it will associate with the AP with strongest signal. If the client is set to a particular SSID, then it will associate with the AP that owns that SSID, no matter signal strenght (obviously assuming the signal is not too low). marco To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
