methods to surf the Internet:
Accessing the Network Through the Embedded PPP Dial-up Software on the
MT886
Accessing the Network Through the PPP Dial-up Software on Your Computer
3.1 Accessing the Network Through the
Embedded PPP Dial-up Software on the
MT886
If you select this method for accessing the network, the MT886 starts to set up a dial-up
connection automatically after the startup. You can access the network after you power
on your computer. You do not need to install any special dial-up software on your
computer or perform dial-up operations on your computer. To configure the MT886
and your computer for the network access, do as follows:
Step 1 Log in to the Web-based configuration utility of the MT886.
1. Launch the Internet Explorer on your computer. Enter http://192.168.1.1
in the address bar, and then press Enter.
2. In the displayed dialog box, enter the user name and the password, and
then click OK.
By default, the user name is admin and the password is admin. After the
user name and the password are verified, you can access the Web-based
configuration utility.
Step 2 Enable the embedded dial-up function.
1. In the navigation tree on the left of the Web-based configuration utility,
choose Basic > WAN Setting.
2. Select a PVC number, such as 1, from the PVC drop-down combo box.

You need to perform the preceding operations on a computer once only. The next time
when you power on your computer, you can surf the Internet without any configuration.
3.2 Accessing the Network Through the PPP
Dial-up Software on Your Computer
If you select this method for accessing the network, you need to install and configure
the dial-up software on your computer. In addition, you need to perform dial-up
operations on your computer upon each startup. To configure the MT886 and your
computer for the network access, do as follows:
Step 1 Set the working mode of the MT886 to Bridge.
For details, refer to the procedure for enabling the embedded dial-up function
described in Step 2 in section 3.1 "Accessing the Network Through the
Embedded PPP Dial-up Software on the MT886." Note that Bridge is
selected from the Mode drop-down combo box.
Step 2 Install and configure the PPP dial-up software on your computer.
The PPP dial-up software is pre-installed on certain computer operating
systems. To create a dial-up connection, do as follows (taking the Windows
XP operating system as an example):

8. Enter the user name and password provided by the network operator and
used for the dial-up connection, and then click Next.
9. Select Add a shortcut to this connection to my desktop, and then click
Finish.
An icon for the dial-up connection is displayed on the desktop of your
computer.
You need to perform the preceding operations only once for creating a network
connection. After the network connection is created, to access the network,
double-click the icon for the dial-up connection, and then click Connect in the
displayed dialog box.

5 FAQs
How can I quickly restore the default settings of the terminal?
To restore the
default settings, press and hold the RESET button on the rear panel for
over six seconds after the MT886 is powered on, and then release the button.
What can I do if I cannot access the Internet through the terminal?
Step 1 Check whether the POWER indicator on the terminal is solid on.
If the POWER indicator is off, perform further checks as follows:
1. Ensure that the terminal is turned on.
2.
Ensure that electricity comes from the socket and that the power input
from the socket meets the requirements described on the label of the
terminal power adapter. If the voltage is unsteady, for example, if the
voltage is too high or too low, do not use the terminal. Wait until the
voltage restores to its normal level, and then use the terminal.

8
3. Ensure that the terminal is properly connected to the socket through
the power adapter.
If the POWER indicator is still off, contact an authorized maintenance
center.
Step 2
After powering on the terminal, wait for about three minutes. Then, check
whether the ADSL indicator on the terminal is solid on.
If the ADSL indicator blinks for a long time, perform further checks as
follows:
1. Ensure that telephone lines are properly connected. Pay special
attention to the connections between the telephone lines and the
splitter.
2. Ensure that the terminal or telephone lines are far from the electric
appliances that generate strong magnetic or electric fields. Replace
telephone lines when necessary.
If the ADSL indicator still blinks and does not turn solid on, contact your
network operator.
Step 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. 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

9
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)
Settings dialog box, ensure that the Use a proxy server for your
LAN (These settings will not apply to dial-up or VPN
connections). check box is cleared.
Step 8 Try to access multiple Web sites to check whether the terminal can access
these Web sites.
If the terminal still cannot access Web sites, contact your network service
provider.
What can I do if Web pages often cannot be displayed during Web page browsing
and can be displayed after the terminal is restarted?
Step 1 Ensure that the terminal and other devices, such as telephones or fax
machines, are connected to telephone lines through a splitter.
For details about how to install a splitter, see the related description in the
manual.
Step 2 Ensure that telephone lines are properly connected.
If the telephone lines are improperly connected, the stability of the
network connection is affected.
Step 3 Check the positions of your terminal and your computer. Ensure that they
are far from electric appliances, such as microwave ovens, refrigerators, or
cordless telephones, that generate strong magnetic or electric fields.

10
If the problem persists, contact your service provider.
After a broadband terminal is installed, does Internet access degrade call quality or
do telephone calls lower the Internet access rate?
No. The terminal uses the frequency division multiplexing (FDM) and splitter
technologies to separate voice signals from data signals. Although the two types of
signals are transmitted through one telephone line, they are carried by different
frequency bands. Therefore, they do not interfere with each other. In this case, you
can make a telephone call and access the Internet simultaneously, without degrading
call quality or lowering the Internet access rate.
