Guest loses internet after around 2 hours

Description
After around 2 hours (sometimes less than 2 hours, sometimes more, it seems to vary), my Windows 10 guest will lose internet access. At the same time the internet works fine on the Windows 10 host, so it's not an internet or ISP connectvity issue.
This started with v7.1.0 and continues to happen v7.1.2.
Although I have attached a log file, further log files from v7.1.0 can be found in my thread here: https://forums.virtualbox.org/viewtopic.php?p=550937

This is really a copy and paste from my post in the forum:
I've noticed something odd happens, which also happened with v7.1.0 but I dismissed it as a fluke. When I load Firefox in the VM, no websites can be found. I haven't tried Edge yet, but I will the next time it happens. My monitor reports that the three test sites are unreachable, so I doubt Edge would work anyway. The weird thing is that the torrents appears to be working, perhaps just slower though. I'm wondering if this is a DNS issue of some sort? But the host's internet is fine at the same time that the guest's internet appears to be down.

I'd appreciate any suggestions of free software that could do this.
Replying to boxer01:
I saw you use some watchdog software on your guest to monitor your connection. The time of the total lost of connection differs, as you already wrote. I think, that the time depends on the amount of transferred data.
It would be interesting if you could log the uploaded and downloaded volume per second till the complete lost of the connection. I don't know if this software you are using can do the logging for some time. Something like the information we see in the session information window, but for a bigger timespan.
Another test improvement idea: if you use torrents to test, the speed of download and upload isn't constant, it could vary from one second to another. So if you start some endless internet test with constant traffic volume, I think that the connection will be lost after nearly the same time. And not after different time like it happens now.

A quick search gave me these results: there is a command-line script that simply writes the values to the CSV file. Or there is software called bitmeteros (there is a second version required .NET) which monitors and logs the bandwidth.
