I have Comcast/Xfinity as my service provider and have suddenly run into a situation where my data usage has jumped 50% for no apparent reason. The last two months we've hit the 1TB data cap and have now used up our "grace months". I need to be able to monitor the data usage for all devides on my network but don't see a way to do this on the Archer C9 AC1900. Does anyone know of an application that can do this?
