Edimax Router AR-7265WnA User Manual

							 63 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. 
 
 
 
  
						

							 64 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. 
 
 
  
						

							 66 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).  
 
  
						

							 67 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 
ISPs 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 
 
 
 
 
  
						

							 68 NAT 
Network Address Translator is defined by RFC 1631. Enable a LAN network to 
use one set of IP address for internal traffic. A NAT box located where the LAN 
meets the Internet provides the necessary IP address translation. This helps 
provide a sort of firewall and allow for a wider address range to be used internally 
without danger of conflict. Using the router’s NAT capability, you can access the 
Internet from any computer on your home network without having to purchase 
more IP addresses from your ISP. 
 
Port 
Network Clients (LAN PC) uses port numbers to distinguish one network 
application/protocol over another. Below is a list of common applications and 
protocol/port numbers: 
 
Application Protocol Port Number
Telnet TCP 23 
FTP TCP 21 
SMTP TCP 25 
POP3 TCP 110 
H.323 TCP 1720 
SNMP UCP 161 
SNMP Trap  UDP  162 
HTTP TCP 80 
PPTP TCP 1723 
PC Anywhere TCP  5631

PPP 
PPP is the Point-to-Point-Protocol. The successor to SLIP, PPP provides router-
to-router and host-to-network connections over both synchronous and 
asynchronous circuits. 
 
 
 
  
						

							 69 PPPoA (RFC 2364) 
The Point-to-Point Protocol (PPP) provides a standard method for transporting 
multi-protocol data grams over point-to-point links. This document describes the 
use of ATM Adaptation Layer 5 (AAL5) for framing PPP encapsulated packets. 
 
PPPoE (RFC 2516) 
This document describes how to build PPP sessions and encapsulate PPP 
packets over Ethernet. PPP over Ethernet (PPPoE) provides the ability to 
connect a network of hosts over a simple bridging access device to a remote 
Access Concentrator. 
 
Protocol 
A protocol is a set of rules for interaction agreed upon between multiple parties 
so that when they interface with each other based on such a protocol, the 
interpretation of their behavior is well defined and can be made objectively, 
without confusion or misunderstanding.  
 
PVC 
Permanent Virtual Circuit, connection-oriented permanent leased line circuit 
between end-stations on a network over a separate ATM circuit. 
 
RFC 
Request for Comments. The document series, begun in 1969, which describes 
the Internet suite of protocols and related experiments. Not all RFCs describe 
Internet standards, but all Internet standards are written up as RFCs. 
 
RFC 1483 
Multi-protocol encapsulation over AAL-5. Two encapsulation methods for carrying 
network interconnect traffic over ATM AAL-5. The first method allows multiplexing 
of multiple protocols over a single ATM virtual circuit. The protocol of a carried 
PDU is identified by prefixing the PDU by an IEEE 802.2 Logical Link Control 
(LLC) header. This method is in the following called LLC Encapsulation. The 
second method does higher-layer protocol multiplexing implicitly by ATM Virtual 
Circuits (VCs). It is in the following called VC Based Multiplexing. 
  
						

							 70 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. 
 
  
						

							 71 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.
