In my previous post, the ICON is on the bottom right, not left.

I have been on Internet for about half an hour now, and MY VOLUME Thing says that I have used 21 Megabytes.
My Computer tells me I have used 1.4 Megabytes

You see the difference?
Don't go by that Volume thing..its silly.. just ignore it.
It is mainly happening because the modem keeps dropping out and reconnecting.

I wonder if you have changed the hours you spend on Internet Partypooper.
At Peak Periods, like after 5pm or so, the Phone Network gets very busy and downloads are very slow.
