Logout

To exit the router web interface, choose Logout. Please save your configuration setting before logging out of the system.

Be aware that the router configuration interface can only be accessed by one PC at a time.

Therefore when a PC has logged into the system interface, the other users cannot access the system interface until the current user has logged out of the system. If the previous user forgets to logout, the second PC can only access the router web interface after a user-defined auto logout period which is by default 3 minutes. You can however modify the value of the auto logout period using the Advanced > Device Management section of the router web interface. Please see the

Advanced section of this manual for more information.

ADSL LED on the front panel should lit. Check that your VPI, VCI, encapsulation type and type of multi- plexing settings are the same as those provided by your ISP. Reboot the router GE. If you still have prob- lem, you may need to verify these settings with your

ISP.

Make sure that all devices (e.g telephone, fax ma- chine, analogue modems) that are connected to the telephone line as your router have a line filter con- nected between them and the wall outlet (unless your are using a Central Splitter or Central Filter installed by a qualified and licensed electrician). Make sure that alll line filters are correctly installed as missing line filters or incorrect installation of line filters can cause ADSL connection problem, including frequent disconnec- tions.
