Hi, John.

This is a rough one to troubleshoot. It sounds like there's some kind of issue with something running on your machine, since the error *did* occur with PING at the same time as PingPlotter.

I'd start out by switching to ICMP raw sockets and see if that changes things - maybe there's just an issue with ICMP.DLL. Then, maybe try running PingPlotter on a your neighbor's machine.

We have a couple of articles that touch on this topic a bit:

and

See if that gets you an ideas.

It does seem like a local PC issue rather than a router issue, based on the "General Failure" message. Are you getting similar errors in PingPlotter (it will show up above the upper trace graph)?
