My Mikrotik HAP ac Have Small Bytes count on IP Accounting

HI,

I want to ask about MIkrotik IP Accounting feature. I have MikroTik-RB962UiGS-5HacT2HnT (HAP ac) with software version v6.49 and firmware version v6.49.
Below are my screenshot of Winbox connection with me downloading some ISO file from internet. The speed is averaging above 10 Mbps, but why in my Mikrotik IP Accounting the bytes only show very small traffics below 1 Mbps???

Why does the IP Accounting feature on my Mikrotik only accounting traffic size so small?? And the traffic size of IP accounting is way below the the WAN interface traffic tab.

Before I use this type of Mikrotik, I use RB951G-2HnD and with same network and settings and the IP Accounting feature showing correct bytes count same as the WAN interface traffic tab.

Not a direct reply to your question, but IP Accounting is going a way (not included in v7). I have used it in my Splunk MikroTik monotoring. Se link in my signature.

So to still get accounting data from each client in v7, I moved over to use Kid Control that gives much of the same information (set up correctly)
