Hello!

Long story short I'm fighting with my ISP for a long time now but they can't see the issue I'm having even when I've provided them pingplotter reports.

I would like to ask for some help interpeting my resutls to see if I was mistaken, or the ISP is the one who doesn't know what they are doing.

I've attached two pictures which I need help with. First hop is the home gateway, the second one is the CMTS of the ISP. No matter what I ping the packet loss starts to show up starting the second hop. Is it even a packet loss? In the bottom graph it always shows up as a 100% packet loss, so could it be that the internet is cutting off for random periods of times somewhere between the HGW and the CMTS?

Please someone help me telling what could be the problem because it makes my internet unusable and my ISP doesn't want to acknowledge that the problem is there.

Edit: I've added a sample set from today in the hopes that it might be easier to find where the issue is.
