Wireless Basics
D-Link wireless products are based on industry standards to provide easy-to-use and compatible
high-speed wireless connectivity within your home, business, or on public access wireless networks.
D-Link wireless products will allow you access to the data you want, when and where you want it. You
will be able to enjoy the freedom that wireless networking brings.
A WLAN is a cellular computer network that transmits and receives data with radio signals instead of
wires. WLANs are used increasingly in both home and office environments, and public areas such as
airports, coffee shops and universities. Innovative ways to utilize WLAN technology are helping people
to work and communicate more efficiently. Increased mobility and the absence of cabling and other
fixed infrastructure have proven to be beneficial for many users.
Wireless users can use the same applications they use on a wired network.  Wireless adapter cards
used on laptop and desktop systems support the same protocols as Ethernet adapter cards.
People use wireless LAN technology for many different purposes:
Mobility - Productivity increases when people have access to data in any location within the operating
range of the WLAN.  Management decisions based on real-time information can significantly improve
worker efficiency.
Low Implementation Costs – WLANs are easy to set up, manage, change and relocate. Networks
that frequently change can benefit from WLANs ease of implementation. WLANs can operate in
locations where installation of wiring may be impractical.
Installation and Network Expansion - Installing a WLAN system can be fast and easy and can
eliminate the need to pull cable through walls and ceilings. Wireless technology allows the network to
go where wires cannot go - even outside the home or office.
Scalability – WLANs can be configured in a variety of topologies to meet the needs of specific
applications and installations. Configurations are easily changed and range from peer-to-peer networks
suitable for a small number of users to larger infrastructure networks to accommodate hundreds or
thousands of users, depending on the number of wireless devices deployed.
Inexpensive Solution - Wireless network devices are as competitively priced as conventional Ethernet
network devices.

Standards-based Technology
The  DGL-4300 Wireless Broadband Router utilizes the new 802.11g standard.
The IEEE 802.11g standard is an extension of the 802.11b standard.  It increases the data rate up to
54Mbps within the 2.4GHz band, utilizing OFDM technology.
This means that in most environments, within the specified range of this device, you will be able to
transfer large files quickly or even watch a movie in MPEG format over your network without noticeable
delays. This technology works by transmitting high-speed digital data over a radio wave utilizing
OFDM (Orthogonal Frequency Division Multiplexing) technology. OFDM works by splitting the radio
signal into multiple smaller sub-signals that are then transmitted simultaneously at different frequencies
to the receiver.  OFDM reduces the amount of crosstalk (interference) in signal transmissions.
The DGL-4300 is backwards compatible with 802.11b devices. This means that if you have an existing
802.11b network, the devices in that network will be compatible with 802.11g devices at speeds of
up to 11Mbps in the 2.4GHz range.
Installation Considerations
The D-Link DGL-4300 lets you access your network, using a wireless connection, from virtually
anywhere within its operating range. Keep in mind, however, that the number, thickness and location
of walls, ceilings, or other objects that the wireless signals must pass through, may limit the range.
Typical ranges vary depending on the types of materials and background RF (radio frequency) noise
in your home or business. The key to maximizing wireless range is to follow these basic guidelines:
„Keep the number of walls and ceilings between the DGL-4300 and other network devices  to a
minimum - each wall or ceiling can reduce your D-Link wireless product’s range from 3-90 feet
(1-30 meters). Position your devices so that the number of walls or ceilings is minimized.
„Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a
45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42
feet (14 meters) thick! Position devices so that the signal will travel straight through a wall or
ceiling (instead of at an angle) for better reception.
„Building Materials can impede the wireless signal - a solid metal door or aluminum studs may
have a negative effect on range. Try to position wireless devices and computers with wireless
adapters so that the signal passes through drywall or open doorways and not other materials.
„Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances
that generate extreme RF noise.

WAN
The WAN section is where your Internet Connection mode is selected. Your Internet Service Provider
(ISP) determines the type of connection that you use.
Modes
There are three connection modes to choose from as shown below. If you are unsure of your connection
settings, contact your Internet Service Provider (ISP) and you can enter the necessary information
on the QIG or print this page and write the settings for future reference.
Primary DNS Server: _____._____._____._____
Secondary DNS Server: _____._____._____._____
„Static: Used when your ISP provides you a set IP address that does not change. The IP information
is manually entered in your IP configuration settings.
IP Address: _____._____._____._____
Subnet Mask: _____._____._____._____
Default Gateway: _____._____._____._____
„DHCP: A method of connection where the ISP assigns your IP address when your computer
requests one from the ISP’s server. Some ISP’s require you to make some settings on your side
before your computer can connect to the Internet.
Host Name:______________________
„PPPoE: A method of connection that requires you to enter a Username and Password (provided
by your Internet Service Provider) to gain access to the Internet.
Username:______________________
Password:______________________
Service Name (Optional):______________________
All three modes have some common configuration options. The Primary and Secondary DNS Server
settings are required for Static configurations and optional for DHCP and PPPoE configurations. The
Advanced options on the following page can be modified for any of the three connection modes.
You should be able to get the Primary DNS and Secondary DNS Servers settings from your router
configuration settings, ISP, or your network administrator. Only the primary DNS server address is
required, though it is best to have both the primary and secondary addresses.

Advanced
The Advanced options apply to all WAN modes.
The MTU (Maximum Transmission Unit) is a parameter that determines the
largest packet size (in bytes) that the router will send to the WAN. If LAN
devices send larger packets, the router will break them into smaller packets.
Ideally, you should set this to match the MTU of the connection to your ISP.
Typical values are 1500 bytes for an Ethernet connection and 1492 bytes
for a PPPoE connection. If the router’s MTU is set too high, packets will be
fragmented downstream. If the router’s MTU is set too low, the router will
fragment packets unnecessarily and in extreme cases may be unable to
establish some connections. In either case, network performance can suffer.
This option is enabled by default allowing the router to select the typical
MTU settings for the selected WAN interface. If this option is unchecked, the
router will use the value assigned in the MTU field.
The WAN Port Speed is set to auto by default. If you have trouble connecting
the WAN port, you can select the connection type (10 or 100Mbps).
This option is disabled by default. By disabling the WAN ping, the router will
not respond to requests from a ping command received via the Internet.
Pinging public WAN IP addresses is a common method used by hackers to
test whether your WAN IP address is valid.
Some ISP’s may check your computer’s MAC address. Each networking
device has it’s own unique MAC address defined by the hardware
manufacturer. Some ISP’s record the MAC address of the network adapter
in the computer used to initially connect to their service. The ISP will then
only grant Internet access to requests from a computer with this particular
MAC address. The D-Link router has a different MAC address than the
computer that initially connected to the ISP. To resolve this problem, enable
this option.
When MAC Cloning is enabled, you can enter in a MAC address manually
in this field or click the Clone Your Computer’s MAC Address button.
When this button is clicked, the WAN port will use the MAC Address of the
network adapter in the computer that you are using to access the router. MTU:
