If traceroute shows the bottleneck to be anywhere but in the first or second hop, then the problem is out of your hands, and in your provider's network, or their provider's network. It could be an intermittently failing DSL modem. It could be a DOS attack on your network segment (far less likely with DSL than with cable service, unless someone is specifically po'ed at you). Ping failures of over 50% would point to either. Run traceroute when your service is acting flakey, and see where it times out. (Note: Traceroute is less useful than it used to be as many providers block UDP traffic at their main network routers, to avoid DOS attacks. If you try to do a tracert to dbdev2.pharmacy.arizona.edu (my desktop here at work), for example, you're likely to be blocked at the arizona.edu domain, unless the campus admins have changed things. But in your case all you ant to see it it get past the first (and possibly second for DSL if your modem is acting as a router) hop. -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs -- G-Books is sponsored by <http://lowendmac.com/> and...
