Hi, It appears that when two IBSS networks are started at the same time they sometimes don't pick each other up and two separate IBSS networks are created. I have turned on IBSS logging and see beacons coming in from both networks AFTER each interface creates its own IBSS, but they dont come soon enough for either interface to realize there is already an IBSS. Is there any mitigation in the kernel or anything outlined in 802.11 that handles this case of two IBSS networks being created simultaneously (or close to it)? Even delaying the second network by a full second sometimes results in this behavior.
