Already seeing discrepancy 189GB vs 178GB just check my Comcast.com account. It says that as of 9/24/2012 we've used 189GB.
My router however, running the latest DD-WRT version, says my WAN port had: September 2012 (Incoming: 138765 MB / Outgoing: 39228 MB) - 177,993MB total
So who's the liar now?!
