As simple as that. And guaranteed to work :) (and BTW this approach is even routing protocol agnostic ;-) Seriously, that is why we have a separation of network layers, that each can fulfill his duty (and layer 3 settings should not try to compensate for problems of the lower layers too much). If you are in a truly interesting environment such as delay tolerant networks, that is of course a whole different thing.
But our practical experience shows: before you start to play around with settings like Juliusz proposed, consider to invest some extra cash into good Wi-Fi equipment (5GHz, good antennas) and improve layer 1 *first*. my 2 cents, OE1SYS _______________________________________________ Babel-users mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/babel-users
