I had an experience with my provider at least 10 years ago. My speed was not up to snuff (now Spectrum). I checked the Gateway and their my speed fell naturally until I got to the Hop, the same HOP I was routed through to get the the AH server. I had ping plotter and identified the bad hop. So what do I do I call my Provider. This is what happens to everyone that contacts their provider.
My call.
Me: I'm suffering serious delays and, my connection is up over 1200ms at times and goes up and down drastically and the connection misses at least at time 60 t0 70 packets that go wobbling into space somewhere.
Level one tech: OK Sir would you get into DOS and run a tracert to microsft.com.
Me: The tracert to microsoft was fast and complete. But I'm not trying to connect to Microsoft but to the Hightech creations server.
To make this short I had to get to a level 3 Tech who was an engineer. I had to stay on the line and raise a big stink until I got the engineer.
I explained to the Engineer what was happening and where. I emailed him the pingplotter route from my gateway, to the bad hop and then finally to the AH server. It showed the missing packetts and that at times 70% of the packetts were lost.
Time-Warner flagged the hop. (Sprint) They repaired the problem and I've had no problems since. What I'm telling you is be firm AND polite. Don't fall for the tracert routine the level1 Techie is basically a screener with little if any knowledge about the internet. Stand firm and polite. Get pingplotter and email it to the engineer. They receive it as fast as you send it by email.
Don't threaten, just have proof of what you are saying. I also had them balance the upload and download of my signal. Remember the first person you call will be someone who knows very little.
