The WDS Tab
Wireless Distribution System (WDS) technology enables several access points
to increase the coverage of a wireless network. Although enterprises or home
users can reduce most wiring problems by using access points that support
WDS, they still need cables to connect external ISP.
Advantages of WDS:
1.
Greater Convenience: It eliminates wiring headaches and connects all
devices wirelessly except for the connection
between ISP and the Router in the networking
environment.
2.
Extended Range:
It can increase the network coverage through the
deployment of additional access points directly
where they are needed.
Note: Your GN-B41G can only create a WDS environment with a GIGABYTE
Access Point (models: GN-A17GU, GN-A11G).

The VPN Pass Through Tab
A Virtual Private Network (VPN) is a type of secured private network connection,
built upon publicly-accessible infrastructure such as the Internet. Typically,
VPNs employ a certain combination of encryption, digital certificates, strict user
authentication and access control to provide security to the data they deliver.
They usually provide connectivity to various devices behind a gateway or
firewall.
The GN-B41G supports Internet-industry standard technologies to provide open
and interoperable VPN solutions, including Internet Protocol Security (IPSec),
Layer 2 Tunneling Protocol (L2TP) and Point-to-Point Tunneling Protocol
(PPTP).

IPSec Pass Through setting
IP Security (IPSec) provides authentication and encryption. Since it is
mainly a Layer 3 technology, it can secure all data on the network. It has
become a standard protocol used with Virtual Private Networks (VPNs).
L2TP Pass Through setting
Layer 2 Tunneling Protocol (L2TP) is an extension of the Point-to-Point
Tunneling Protocol and is also used to establish virtual private networks.

Chapter 8 Troubleshooting
This sections provides solutions to common problems that may occur during
installation, configuration or use of the GN-B41G.
Q: I can’t remember the password or IP address of the router.
A: You can create a new new password by pressing the “Init” button on the
bottom of the router. The Router will reboot and all settings will be
restored to their default values.
Q: I can’t connect to the Internet
A: 1.
Check that the power cord is connected properly, and the router’s
power LED is lit green.
2.
3.
Verify that all the configuration settings are correct.
Check that your ADSL/Cable Modem is operating normally, and/or
you have ISP service available.
4.
Check that all network cabling is properly connected.
Q: I can’t access the GN-B41G Web Configuration Utility.
A: 1.
Please check the Ethernet between the PC and the Router is
properly connected.
2.
3.
Make sure your computer’s IP address is on the subnet where the
Router locates.
Make sure you are using the correct login information.
Q: Where in the network do I connect the router?
A: In a typical environment, the GN-B41G is installed between ADSL/Cable
Modem and LAN. Plug the Router into the Ethernet port of ADSL or Cable
Modem.
Q: Can the GN-B41G work as a DHCP server?
A: Yes. GN-B41G has a built-in DHCP server function so that apart from all
the standard DHCP functions, it helps prevent IP conflicts.
Q: What is WEP?
A: Wired Equivalent Privacy (WEP) is a security mechanism defined within
the 802.11 standard. It is designed to make the link integrity of the
wireless medium equal to wired cable. Data privacy mechanism based on
a 40 bits (128 bit optional) shared key algorithm, as described in the IEEE
802.11 standard.

Appendix A: Glossary
ADSL
Asymmetric digital subscriber line (ADSL) is a new modem technology that
converts existing twisted-pair telephone lines into access paths for high-speed
communication of various sorts.
Auto-MDI/MDIX
On a network hub or switch, an auto-MDI/MDIX port automatically senses if it
needs to act as a MDI or MDIX port. The auto- MDI/MDIX capability eliminates
the need for crossover cables.
Auto-negotiate
To automatically determine the correct setting. The term is often used with
communications and networking
DHCP
The Dynamic Host Configuration Protocol (DHCP) is an Internet protocol for
automating the configuration of computers that use TCP/IP. DHCP can be used
to automatically assign IP addresses, to deliver TCP/IP stack configuration
parameters such as the subnet mask and default router, and to provide other
configuration information such as the addresses for printer, time and news
servers.
DMZ
In computer networks, a DMZ (demilitarized zone) is a computer host or small
network inserted as a "neutral zone" between a company's private network and
the outside public network. It prevents outside users from getting direct access
to a server that stores company data. Typically, the DMZ contains devices
accessible to Internet traffic, such as Web (HTTP) servers, FTP servers, SMTP
(e-mail) servers and DNS servers.
DNS
The Domain Name System (DNS) is a distributed Internet directory service.
DNS is used mostly to translate between domain names and IP addresses, and
to control Internet email delivery. Most Internet services rely on DNS to work. If
DNS fails, web sites cannot be located and email delivery service will be
suspended.
Dynamic IP Address
An IP address is automatically assigned to a user’s AP in a TCP/IP network
typically by a DHCP server.

Firewall
A system designed to prevent unauthorized access to or from a private network.
Firewalls can be implemented in both hardware and software, or a combination
of both. Firewalls are frequently used to prevent unauthorized Internet users
from accessing private networks connected to the Internet, especially intranets.
All messages entering or leaving the intranet pass through the firewall, which
examines each message and blocks those that do not meet the specified
security criteria.
Gateway
A device, usually a Router, that connects hosts on a local network to other
networks.
IP Address
Every PC on the Internet has a unique identifying number, called an IP Address.
A typical IP address looks like this: 216.27.61.137
IPSec
IPSec stands for IP Security. It provides authentication and encryption over the
Internet. It functions at Layer 3 and thus secures everything on the network. It
has become a standard protocol used for virtual private networks (VPNs).
MAC Address
On a local area network (LAN) or other network, the MAC (Media Access
Control) address is your computer's unique hardware number. Usually written
as: 01:23:45:67:89:ab
MTU
The size in bytes of the largest packet that can be sent or received.
NAT
A technique by which several hosts share a single IP address for accessing to
the Internet.
Ping (Packet Internet Groper)
A utility to determine whether a specific IP address is accessible. It works by
sending a packet to the specified address and waiting for a reply. PING is used
primarily to troubleshoot Internet connections.
SSID
SSID is the name representing the Router in WLAN.

PPPoE
Point-to-Point over Ethernet is a protocol for connecting remote hosts to the
Internet over an always-on connection by simulating a dial-up connection.
Router
A device that forwards data packets along networks. A router is connected to at
least two networks, commonly two LANs or WANs or a LAN and its ISP
network. Routers are located at gateways, the places where two or more
networks connect.
Subnet Mask
A mask used to determine which subnet an IP address belongs to. An IP
address has two components, the network address and the host address.
Subnetting enables the network administrator to further divide the host part of
the address into two or more subnets.
TCP/IP
TCP/IP (Transmission Control Protocol/Internet Protocol), the suite of
communications protocols used to connect hosts on the Internet.
VPN
Virtual private networks are secured private network connections, built on top of
publicly accessible infrastructure, such as the Internet or the public telephone
network. VPNs typically employ some combination of encryption, digital
certificates, strong user authentication and access control to provide security to
the traffic they carry. They usually provide connectivity to many machines
behind a gateway or firewall.
WAN
Wide Area Network, a communication network that covers a relatively broad
geographic area, consisting of two or more LANs. Broadband communication
over the WAN is often through public networks such as the ADSL or Cable
systems, or through leased lines or satellites. To simplify it, please image
network as a WAN.
