Installed this router on 15th Feb 2025.
Updated the firmware immediately.
Monitored the traffic usage uop and down.

Noticed a massive increase in the data use.

Checked with my ISP who provided their data usage figures for same period.

The figures reported o n the BE550 were over 90% higher.  Example:

Up 2144mb (ISP), Up 227300mb (BE550).  Down 7621 (ISP), 116400 (BE550)

Up 2372mb (ISP), Up 2273900 (BE550).  Down 12769 (ISP), 275000 (BE550) - yes over 2.2TB!!!

Clearly the TPLINK hardware/Firmware/Softawre is misreporting the traffic usage.

I have fully checked all wifi and Ethernet systems, fully scanned, no issues.

ISP State my usage has remained in a constant average for last year or so.
Can TPLINK check, explain, reassure?
