Severe packet loss issues, what do I tell my ISP?

I keep telling my ISP I have packet loss issues, but they keep telling me my line is fine. What should I tell them, or ask them to do to fix the issue? What's wrong with my line (which seems to be the problem)?

Actually, it looks like your hop 1 packet loss is just as bad as it is downstream - and hop 1 is inside your own network. Based on this, I'd say the problem is with your own network, *not* your ISP.

If you're using wireless, then that could have issues and be causing packet loss. If it's wired, then look for a bad router / hub / network cable.

The latency at hop 1 is 0ms, which usually means it's in your network, not the ISPs.
