You could be dropped from 2 areas.
On the WAN side, ISP generally drop users after a period of time, leased time. Nothing you can do for that one, it should auto reconnect.
Connect to the admin pages through your browser. Enter PW, You did add a password, didn't you. Once you have done the initial setup no need to use the utility any more.
On the LAN side there is a setting for adjusting how long to keep the connection. This time can be adjusted from 30 min to unlimited. Increase to max. Also set your logging to only log errors, default is all activity. Verify the firewall is active. Respond to ping OFF.
If you are having a connection problem, clone your MAC address into the router from the computer used to setup the DSL connection originally.
