6. Troubleshooting

1. The LAN LED on the front panel does not light up. STEPS CORRECTIVE ACTION Check the Ethernet cable connections between your ADSL2+ Router and the computer or hub. Check for faulty Ethernet cables. Make sure your computers Ethernet card is working properly. If these steps fail to correct the problem, contact your local distributor for assistance.
2. The ADSL LED on the front panel does not light up. STEPS CORRECTIVE ACTION Check the telephone wire and connections between ADSL2+ Router DSL port and the wall jack. Make sure that the telephone company has checked your phone line and set it up for DSL service. Reset your ADSL line to reinitialize your link to the DSLAM. If these steps fail to correct the problem, contact your local distributor for assistance.

3. I cannot access the web management. STEPS 3 CORRECTIVE ACTION Make sure you are using the correct IP address of ADSL2+ Router. Check the IP address of ADSL2+ Router. Your computer and ADSL2+ Routers IP addresses must be on the same subnet for LAN access. If you changed ADSL2+ Routers LAN IP address, then enter the new one as the URL.
The following procedures will help you to check the current IP Address setting of your computer. You can compare if your computer and routers IP Addresses are in the same subnet. Step 1: Click Start and select Run. Step 2: Type in cmd and click OK.
Step 3: Type ipconfig /all and click enter.
Your PCs IP address is 192.168.2.111. The PCs Subnet Mask is 255.255.255.0. Your PCs MAC Address is the one entitled Physical Address (00-00-E2-82C3-AD).
4. I forget my login username and/or password. STEPS 1 CORRECTIVE ACTION 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 1 CORRECTIVE ACTION 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. If you cannot access the Web Management of the router, please press the Reset button over 5 seconds to restore to defaults. 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 1 CORRECTIVE ACTION 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. Check VPI, VCI, type of encapsulation and type of multiplexing settings are the same as what you collected from your ISP. 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 1 CORRECTIVE ACTION 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 PPoA 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 3 CORRECTIVE ACTION Check the schedule rules. If you use PPPoA or PPPoE encapsulation, check the idle timeout setting. 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 gateways 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).

Router A system responsible for making decisions about which of several paths network (or Internet) traffic will follow. To do this, it uses a routing protocol to gain information about the network and algorithms to choose the best route based on several criteria known as "routing metrics. Subnet Mask A subnet mask, which may be a part of the TCP/IP information provided by your ISP, is a set of four numbers (e.g. 255.255.255.0) configured like an IP address. It is used to create IP address numbers used only within a particular network (as opposed to valid IP address numbers recognized by the Internet, which must be assigned by InterNIC). TCP/IP, UDP Transmission Control Protocol/Internet Protocol (TCP/IP) and Unreliable Datagram Protocol (UDP). TCP/IP is the standard protocol for data transmission over the Internet. Both TCP and UDP are transport layer protocol. TCP performs proper error detection and error recovery, and thus is reliable. UDP on the other hand is not reliable. They both run on top of the IP (Internet Protocol), a network layer protocol. TELNET It is the virtual terminal protocol in the Internet suite of protocols. Allows users of one host to log into a remote host and act as normal terminal users of that host. VCI Virtual Circuit Identifier is part of the ATM cell header. A VCI is a tag indicating the channel over which a cell will travel. The VCI of a cell can be changed as it moves between switches via Signaling. VPI Virtual Path Identifier is part of the ATM cell header. A VPI is a pipe for a number of Virtual Circuits.
WAN Wide Area Network is a network that connects computers located in geographically separate areas (e.g. different buildings, cities, countries). The Internet is a wide area network. Web-based management Graphical User Interface (GUI) Many devices support a graphical user interface that is based on the web browser. This means the user can use the familiar Netscape or Microsoft Internet Explorer to Control/configure or monitor the device being managed.
