You can awake your modem up by this function.
If your modem suspends, you can use this function to wake your connection.

Although you use Ping Now function; If it cannot awake your connection, the reason is your bad connection or previous Ping request is not completed yet. You must have IE 4.0 or higher installed to use Ping Now and Super-ping Tool. If you are using a firewall software, please set your firewall to accept incoming and outgoing connections for BeFaster Lite.
When you Register BeFaster Lite,
Note: Super-Ping Tool and Ping Now have
different functions: Super-Ping Tool prevents connection drops. Ping Now awakes
suspended modems. For example; think that you're surfing on the net and your
browser is saying "loading page..." but when you look your modem, you see that
there's not any activity on modem lights. At that time, just use Ping Now
function to awake your modem and speed up your surfing...
