when it is down.
• Time-based Connecting - The connection will only be established in the period
from the start time to the end time (both are in HH:MM format).
• Connect Manually - You can click Connect/Disconnect to connect/disconnect
immediately. This mode also supports the Max Idle Time function as Connect
on Demand mode. The Internet connection can be disconnected automatically
after a specified inactivity period (Max Idle Time) and not be able to re-establish

applications are visiting the Internet continually in the background.
If you want to do some advanced configurations, please click Advanced.
