3) Replace telephone lines.
If the ADSL indicator still blinks, contact your network service provider.
3. Check whether the LAN indicator of the terminal is on.
If the LAN indicator is off, perform further checks as follows:
1) Ensure that the network adapter of the computer is enabled.
2) Ensure that the network cable between the terminal and the computer
is properly connected.
3) Remove and then insert the network cable or replace the network
cable.
If the LAN LINK indicator is still off, contact an authorized maintenance
center.
4. Check whether the driver for the network adapter is properly installed.
Take a computer that runs Windows XP as an example. To check whether
the driver for the network adapter is installed, do as follows:
1) On the desktop, right-click My Computer and choose Manage.
2) In the navigation tree of the Computer Management window, choose
Device Manager.
3) In the right pane of the Computer Management window, click Network
adapters to view the information about the network adapter of the
computer.
If no network adapter is detected or if a question mark (?) or an
exclamation mark (!) is displayed next to the icon of the network adapter,
you can infer that the driver for the network adapter is not properly installed.
In this case, re-install the driver for the network adapter of the computer.
5. Ensure that you have entered the correct user name and user password
that are required by the PPP dialing software.
6. Check whether you can use the PPP dialing software to dial successfully.
If you cannot use the PPP dialing software to dial successfully, perform
further checks as follows:
1) Stop the PPP dialing software and then power off the terminal. After five
minutes, power on the terminal and use the PPP dialing software to dial
again.
