I have Win8.1 PC , and I want to know how much kilobyte of internet data did I used but under the Wi-Fi connection which connect to internet is just written: "Estimated usage" , and no amount of data usage exist.
I search for a solution in the internet , and I do 3 works:
I have checked the settings-->Change computer setting-->Network-->Connections-->(selecting that Wi-Fi Network connection) to see "Estimated Network data use" was on.
and another advice told to check for the "Diagnostic Policy Service" service to be Automatic and another advice to delete the Wi-Fi profile, but none of them works.
Please help me with this, thank you.
