    88Unfortunately, this algorithm and/or implementation is not very good and even relatively small networks, nodes that have the same 'essid' will end up with different a 'bssid'. Since the wifi card drivers filter by bsssid, nodes that should be in the same ad-hoc network can't exchange packets.
    99
    10 The solution to this problem can be found by modifying the madwifi drivers (for Atheros wifi cards only), so that the bssid a node generates is a hash of the essid instead of its MAC address. This ensures that nodes with indentical essid's end up with identical bssid's.

    1212Although it has not been extensively tested with non-modified nodes, this modification to the madwifi drivers should be fully backwards compatible with non-modified nodes.
