problem with Networx charts

I use Networx with my mobile internet.
Situation :
My only computer is connected to :
* modem Huawei 353 s-2 or
* by LAN to router TP-Link MR3420 + modem Huawei 353 s-2

When I plug my modem directly in my PC -> Networx chart/graph looks and is correct ;
see attachment # 1.

But when I plug my modem in my router (router connected to PC by LAN) I get this :
see attachment # 2.

Downloaded file was the same in both cases.

My internet is free service with serious limitations : 0,50 Mb/s (D=blue) and 0,25 (U=yellow) .
The results of speedtests from the second chart/graph are here :

Question : WHY THE SECOND CHART/GRAPH (router in use) IS NOT CORRECT AND LOOKS SO STRANGE ?
(esp. upload speeds look completely wrong in the second chart)
ANY SOLUTION ?

.

Not sure, but it seems there is some sort filtering software or virtual adapters present in the system.

Try choosing the LAN interface connected to the router in the list of adapters to monitor in NetWorx, so it does not take into account any other adapters that may be present.

@Andrew
Thank you for your suggestion.
Yes, you are right. There is VMWare Workstation installed in my system (W7 x64).
Probably its filters caused the problem.

There was "all connections" as default setting set in my Networx "Preferences" and it resulted in the strange graph.
I changed it to "all connections - ethernet" (is this the same as LAN ?) but the strange grath was still there.
Finally I found that I can get the right graph setting monitored interface to " Realtek PCIe GBE Family Controller" or "Realtek PCIe GBE Family Controller - RRNetCap Miniport". Only these two work well !
I am used to deal with just desktop or laptop. Never have any network to deal with before.
So I don`t really know what will be monitored when the above setting is "Realtek PCIe GBE Family Controller" or "Realtek PCIe GBE Family Controller - RRNetCap Miniport". Will it be the same as "all connections" in my case anyway ?
Thank you in advance for your helpful remarks.

I had some problems with editing my last post.
I wanted to add 2 links to my screenshots (JPG), but something went wrong.
Sorry.

Here they are :

All connections means really all. In this case NetWorx enumerates all adapters in your system, including virtual ones and sums their usage up. If you happen to have a virtual adapter or some filtering software, the results will be incorrect.

So choosing Realtek PCIe GBE Family Controller is a good idea. NetWorx will monitor that adapter only without taking into account any irrelevant readings from other adapters.
