Serious frustration with PingPlotter. It's nice that PingPlotter has advanced features suitable for IT staff, but I'm looking for a simple solution to track the source of internet interruptions over the course of a day or two.

Much of the Knowledge Base is from previous versions of 10 or 20 years ago, and is even http rather than https. The text of the examples it gives sometimes don't correspond to the accompanying screenshot.

"Page not found" is the landing page for "How PingPlotter Works page from the PingPlotter manual" (http://www [DOT] pingplotter [DOT] com/manual/howitworks.html?pk_vid=04002308c12c2c39178001721729cc3f).

However, using that URL as a clue, I found the manual at https://www.pingplotter.com/manual/

It turns out you can also find the manual from the bottom of the Desktop drop-down menu on the home page https://www.pingplotter.com/ or on the "Pricing" page https://www.pingplotter.com/products/
That latter page says "We also provide a free version (1 connection, no remote collection) for home networks. Compare all." but clicking "Compare all" just brings up a comparison of the three paid versions, NOT including the free version.

Downloading for Mac, there was only one choice which when launched turned out to be labelled the "Pro" version (presumably a two week free trial, though it didn't say so or ask permission to set a cookie) which starts at $29/month for one computer suitable for a small office.

The manual says "PingPlotter 5's "Share" feature provides a quick option to distribute your trace data to whoever you need, and it's easy to use!" No, it's not. Once you've mastered the 139 page manual it's probably easy to use, although it's replete with notices that the features mentioned may not be available on some versions, and doesn't say which versions have which features.

This is for my partner who is highly allergic to tech, and simply needs a software that says whether the problem is the laptop, router, modem, or ISP, and provides a document of evidence suitable for giving the ISP if the ISP is the problem.

Does anyone know of a simple non-video guide to using PingPlotter for these basic purposes, if it's capable of them? Or another software that is?
