4. I forget my login username and/or password.
STEPS
CORRECTIVE ACTION
1
If you have changed the password and have now forgotten it, you
will need to upload the default configuration file. This will erase all
custom configurations and restore all of the factory defaults
including the password.
2
Press the Reset button for five seconds, and then release it.
When the LAN LED begins to blink, the defaults have been
restored.
3
The default username is “admin”. The default password is “1234”.
The Password and Username fields are case-sensitive. Make
sure that you enter the correct password and username using the
proper casing.
4
It is highly recommended to change the default username and
password. Make sure you store the username and password in a
save place.
5. I cannot access the Web Management of the router after activating the ACL
function.
STEPS
CORRECTIVE ACTION
1
When ACL is activated, you have to set the ACL rule for allowing
some users to use some services. Check if you have set the
rules. If not, all the users are forbidden using any of service from
LAN or WAN.
2
If you cannot access the Web Management of the router, please
press the Reset button over 5 seconds to restore to defaults.
3
After the router is restarting, log in the router with the default IP
Address 192.168.2.1.

6. Initialization of the ADSL connection failed.
STEPS
CORRECTIVE ACTION
1
Check the cable connections between the ADSL port and the
wall jack. The ADSL LED on the rear panel of the router should
be on.
2
Check VPI, VCI, type of encapsulation and type of multiplexing
settings are the same as what you collected from your ISP.
3
Restart the router. If you still have problems, you may need to
verify your VPI, VCI, type of encapsulation and type of
multiplexing settings with the ISP.
7. I cannot get a WAN IP address from the ISP.
STEPS
CORRECTIVE ACTION
1
The ISP provides the WAN IP address after authenticating you.
Authentication may be through the user name and password, the
MAC address or the host name.
2
The username and password apply to PPPoE and PPPoA
encapsulation only. Make sure that you have entered the correct
Service Type, User Name and Password (be sure to use the
correct casing).
8. Internet connection disconnects.
STEPS
CORRECTIVE ACTION
1
Check the schedule rules.
2
If you use PPPoA or PPPoE encapsulation, check the idle time-
out setting.
3
Contact your ISP.

7. Glossary
10Base-T
It is an Ethernet standard for Local Area Network (LAN). 10Base-T uses a twisted
pair cable with maximum length of 100 meters.
AAL
ATM Adaptation Layer that defines the rules governing segmentation and
reassembly of data into cells. Different AAL types are suited to different traffic
classes.
ADSL
Asymmetric Digital Subscriber Line, as its name showing, is an asymmetrical
data transmission technology with high traffic rate downstream and low traffic
rate upstream. ADSL technology satisfies the bandwidth requirement of
applications, which demand “asymmetric” traffic, such as web surfing, file
download and Video-on-demand (VOD).
ATM
Asynchronous Transfer Mode is a layer 2 protocol supporting high-speed
asynchronous data with advanced traffic management and quality of service
features.
bps
Bits per second, a standard measurement of digital transmission speeds.
Bridge
A device that connects two or more physical networks and forwards packets
between them. Bridges can usually be made to filter packets, that is, to forward
only certain traffic. Related devices are: repeaters which simply forward electrical
signals from one cable to the other and full-fledged routers which make routing
decisions based on several criteria.

CPE
Customer Premises Equipment, such as ADSL router, USB modem.
Default Gateway (Router)
Every non-router IP device needs to configure a default gateway’s IP address.
When the device sends out an IP packet, if the destination is not on the same
network, the device has to send the packet to its default gateway, which will then
send it out towards the destination.
DHCP
Dynamic Host Configuration Protocol, this protocol automatically gives every
computer on your home network an IP address.
DNS Server IP Address
DNS stands for Domain Name System, which allows Internet servers to have a
domain name (such as www.Broadbandrouter.com) and one or more IP
addresses (such as 192.34.45.8). A DNS server keeps a database of Internet
servers and their respective domain names and IP addresses, so that when a
domain name is requested (as in typing "Broadbandrouter.com" into your Internet
browser), the user is sent to the proper IP address. The DNS server IP address
used by the computers on your home network is the location of the DNS server
your ISP has assigned to you.
DSL
Digital Line Subscriber (DSL) technology provides high-speed access over
twisted copper pair for connection to the Internet, LAN interfaces, and to
broadband services such as video-on-demand, distance learning, and video
conferencing.
Ethernet
It is a standard for computer networks. Ethernet networks are connected by
special cables and hubs or switches, and move data around at up to 10/100
million bits per second (Mbps).

FTP
File Transfer Protocol. The Internet protocol (and program) used to transfer files
between hosts.
Idle Timeout
Idle Timeout is designed so that after there is no traffic to the Internet for a pre-
configured amount of time, the connection will automatically be disconnected.
ISP
Internet Service Provider is a business that provides connectivity to the Internet
for individuals and other businesses or organizations.
ISP Gateway Address
The ISP Gateway Address is an IP address for the Internet router located at the
ISP's office.
LAN
Local Area Network is a group of computers and devices connected together in a
relatively small area (such as a house or an office). Your home network is
considered a LAN.
MAC Address
MAC stands for Media Access Control. A MAC address is the hardware address
of a device connected to a network. The MAC address is a unique identifier for a
device with an Ethernet interface. It is comprised of two parts: 3 bytes of data that
corresponds to the Manufacturer ID (unique for each manufacturer), plus 3 bytes
that are often used as the product’s serial number.
MTU
Maximum Transmission Unit
