Connect on Demand – You can configure the router to disconnect your Internet

connection after a specified period of the Internet connectivity (Max Idle Time). If your

Internet connection has been terminated due to inactivity, Connect on Demand enables

the router to automatically re-establish your connection as soon as you attempt to access

the Internet again. If you wish to activate Connect on Demand, click the radio button. If

you want your Internet connection to remain active at all times, enter 0 in the Max Idle

Time field. Otherwise, enter the number of minutes you want to have elapsed before your

Internet connection terminates. Note: Sometimes the connection cannot be disconnected

although you specify a time to Max Idle Time because some applications visit the

Internet continually in the background.

Connect Automatically - Connect automatically after the router is disconnected. To use

this option, click the radio button.

Connect Manually - You can configure the router to make it connect or disconnect

manually. After a specified period of inactivity (Max Idle Time), the router will disconnect

your Internet connection, and not be able to re-establish your connection automatically as

soon as you attempt to access the Internet again. To use this option, click the radio

button. If you want your Internet connection to remain active at all times, enter 0 in the

Max Idle Time field. Otherwise, enter the number in minutes that you wish to have the

Internet connecting last unless a new link requested. Note: Sometimes the connection

cannot be disconnected although you specify a time to Max Idle Time because some

applications visit the Internet continually in the background.
