That doesn't really necessarily solve the problem though... 2) does your DSL connection go down from time to time? maybe it's dropping out and the system isn't recovering properly. 3) next time it goes down, instead of just rerunning the network scripts, see if you can diagnose the situation a little bit. look at the output of ifconfig route and maybe get a dump from iptables. then compare to the state of things when the system is working.
