Download and upload graphs are swapped
3 posts · Closed
My NetWorx graph displays the correct Mbit numbers for download and upload traffic, but for some reason the download graph shows upload, and upload graph shows download.
Basically the whole graph is correct, but it looks like upload and download have been swapped.
This behaviour can occur if you are monitoring your router but selected an incorrect interface.
For example, if your router has multiple interfaces (one facing the WAN and others facing the LAN), and you are monitoring an interface facing the LAN, the readings may appear reversed. This is because, from the router perspective, it is sending data when your PC is receiving it: i.e. what is upload traffic for the router, is download traffic for your PC.
That was absolutely it, I did not even consider it.
By mistake, I had set it to monitor the LAN side through SNMP. It made perfect sense when you said "from the router perspective, it is
sending data". I changed it to WAN and everything is fine now.
Thanks for the assistance.
