Hello,

I purchased a brand-new TPLINK C4000 A20 WiFi router recently (June 2020) and installed it around Oct-2020.

It is working very well.  I have started to probe into the other features. 

The one I have some questions about is the Traffic Monitor.

When this setting is ON, it asks for two parameters:  (a) by device, including ALL  (b)  minutely, hourly or daily.

I turned it ON,selected ALL devices and selected DAILY.  I left it alone for about 4-5 days, then checked again.

The graph changed to a 7-day axis (which is expected), but it couldn't display more than one (1) day's traffic.

I checked the log, and found out that the router resets the data every 24 hours.

I looked everywhere for a setting that would change this, but to no avail.

Also, the Minutely and Hourly features work but there is no feature to look at past traffic -- this means you

must catch the data you want to monitor at that moment (span of 10 minutes to minutely, one day for hourly)

or else it will be gone.

I must be missing something -- unless this is the way its supposed to work.  If so, then the traffic monitor is of limited value.

Hope some expert on this specific product model can provide some tips, guidance or suggestions.

Thankin you in advance.
