I am afraid that's the way the router exposes the numbers. Somehow many routers do not report back usage figures immediately.
In our tests, we downloaded a 100 MB file and the router only reported that when the download had ended. This disrupts the charting, however the aggregated usage figures should remain correct.

Have you been monitoring the router all this time? If so, check if there are periods where NetWorx doesn't see any activity. If that is the case, it's a common issue and here is what happens:
The router box maintains its DL/UL counters which NetWorx polls periodically. The UPnP standard prescribes the counters to be 32-bit unsigned integers. This means they continuously go up from 0 to 4 GB.
Your router however is likely to have a bug in its firmware code and it uses signed integers, which turns the counters negative as soon as they reach 2 GB. So basically NetWorx stops monitoring it once 2 GB of data have passed through the router. After the next 2 GB of data is works again. Then it stops again and so on.
