Ok, I've had a look and it says I've transmitted 137Mb and recived 4.5Gb through the router in 137 hours (which I work out as between 5 and 6 days). So it sounds like I'm shifting just under 1Gb per day. So a monthly limit of 10Gb doesn't sound enough to me!

Thanks for your help - that is very useful
