Hey methuzla,
Thanks for reaching out!
The first screenshot you've provided (erratic results to local router) shows some interesting results. If you're pinging the router while plugged directly into it, you'd usually expect to see <1ms average latency (especially if the cable you're using is only about a meter long). If you've got another cable handy - you might want to try swapping this out to see if it has any effect on your results.
As far as the difference you're seeing in the results in PingPlotter and your command line ping - the first thing I'd recommend looking into is what packet type you're using in PingPlotter ("Edit" -> "Options" -> "Engine"). For best results, you'll want to make sure this is set to "ICMP Using Windows DLL (default)." We've got a knowledge base article that goes over some other potential reasons for differences between PingPlotter and the command prompt results (the article uses "ping -t" as an example, but the ideas here can apply to other ping/traceroute methods as well):
http://www.pingman.com/kb/37I can see the latency spike/packet loss pretty clearly in the other two screenshots you've got; but it's tough to tell exactly *where* this issue might be originating from without being able to see graphs for the other intermediate hops. If you'd like to send us a .pp2 file (or use the "File" -> "Share" option in PIngPlotter and shoot over the link) - we'd be happy to take a closer look at your results and offer any guidance we can from there.
The best way to narrow down your issue is to keep monitoring (continuously) over time to a target that you've been experiencing problems with. Once you've got a good amount of data in PingPlotter, you can start trying to identify any patterns that may be present in your results. You can use that information to start narrowing down potential culprits, and then start isolating and eliminating any variables (that you have control over) to narrow things down from there (all while continuing to trace with PingPlotter - so you can see what does/doesn't have any effect in your results). We've got a great guide that goes over this process (as well as provides quite a few examples) in more detail, which may prove helpful to your cause:
