I run pingplotter pro on a Lenovo laptop i5 processor, Windows 10, no other activity on the laptop.

Object is a company network, where we experience sometimes VPN interruptions. Network is set up as a usual inhouse network with mix of wires and wireless connections, router to cable provider, connected to the world wide chaos.

I ping two sites, one is our VPN server (remote = outside of the local network) and www.google.com. Ping = port 80 access.

When I ping 1 site, no packet loss.
When I ping both sites with a frequency of 2.5 seconds per ping, no packet loss.
When I ping both sites with a frequency of 1 second per ping, I get massive packet loss (> 90%) on both pings on first hop = cable router.

Should I really assume that the cable router cannot digest this amount of traffic? Not realistic, because under normal conditions up to twenty people can work here easily, with substantial traffic.

Or am I trapped by wrong measurement, because, pingplotter is not capable to digest the incoming information fast enough?

Thx for some insight here.
