Have you tried setting RefreshRateMs to something other than 0? The
documentation states that "If zero, there is no guaranteed refresh rate
of the properties."
I don't use this feature myself, as I have found vnstat to be much more
convenient.

Hi,
I am experiencing a problem with the Device.Statistics interface of my
modem. It always shows RxBytes and TxBytes equal 0.

Is this broken?
