I have been provided only 10GB of downloading every moth. so that I want to know the total usage of my connection. where i get this info. my ISP is providing 7GB how can I check what is the speed of this connection. at the notification area it is showing local area connection is 100mbps. can you explain about it.

1. Your ISP can provide the amount of bandwidth used to date. They should have a web page where you can check your account balance.

2. You can check your connection throughput here: http://www.speakeasy.net

3. The local connection speed is the speed that your NIC is running at. It has nothing to do with your Internet connection's bandwidth.
