Just noticed that my data usage for the month so far is tracking at 14.98 GB on the vodafone web site (ultimate naked DSL product), but that the WAN stats on my HG556a router show 2.5 GB up and download combined. I've heard that there are discrepancies between the data figures for some providers, but not nearly as great as the figures above. I suspect I'm looking at the wrong figures on my HG556a router. Are the relevant data figures under Device Info > Statistics > WAN? I've logged in to the router as administrator to get these figures.
