Something wrong in my network

Hi
It’s not a long time that I work with mikrotik.I have a problem with my network bandwidth.
just see the Pic tha I attached then you know it.
info:
Intenet : is default Gateway
MainOffice: workgroup network that connect via PPPoE
AccessPoint: is a bridge network with another device(RB600) that it’s user’s also connect to Internet via PPPoE.

just count the Tx and Rx rates and see the sum of the MainOffice and AccessPoint is not equal to Internet.
If you need more info just tell me.
Thanks.

That doesn’t mean there’s a problem. For example, if you are running Winbox behind the main office interface you’d be seeing quite some traffic being sent out into that network (TX) as the router sends information to the Winbox application.

Are you experiencing an actual issue, or were you just thrown off by the numbers not adding up?

Thanks for your attention
it’s need to add that I connect to my router via Internet.
It’s about 1 week that my users nagging from low speed and when they call me and say this matter, I see this (Internet is used but none of my users have throughput).

Then you need to go to the location, get behind the router, and see if that’s actually the case. Then run Torch to analyze the traffic on the interfaces to determine what is going on.
