If you are an ADSL user with a monthly quota, the ADSL Usage Monitor that shows your monthly download and upload amounts will be very useful for you. When you click on the ADSL Usage Monitor button of the AirTies ADSL Utility, you can see your current download/upload speed as well as the monthly download amounts. This helps you stay within your monthly quota and not pay high usage penalties. And what’s more, the usage data is retained even if there is a power outage or your router is turned off, and continues from where it left off as soon as the router is restarted.
