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. Remove and then insert the network cable or
replace the network cable when necessary.
If the LAN indicator is still off, contact an authorized maintenance center.
Step 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 then 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 found 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.
Step 5
Ensure that you have entered the correct user name and user password that
are required by the PPP dial-up software.
The user name and the user password are provided by your network
operator.
Step 6
Check whether you can use the PPP dial-up software to dial successfully.
If you cannot use the PPP dial-up software to dial successfully, perform
further checks as follows:
1. Stop the PPP dial-up software and then power off the terminal. After
five minutes, power on the terminal, and then use the PPP dial-up
software to dial again.
2. Restore the default settings of the terminal.
If the problem persists, contact your network operator.
Step 7
Check whether the proxy server of the Web browser is correctly
configured. Take the Internet Explorer installed on a computer that runs
Windows XP as an example. To check whether the proxy server of the
Web browser is correctly configured, do as follows:
1. Launch the Internet Explorer.
2. Choose Tools > Internet Options.
3. In the Internet Options dialog box, click the Connections tab.
4. In the Local Area Network (LAN) settings group box, click LAN
Settings.
5. In the Proxy server group box of the Local Area Network (LAN)
