Advanced Wireless
Advanced wireless contains settings which can negatively affect the performance of your router if configured improperly. Do not change these
settings unless you are already familiar with them or have been instructed to make the change by one of our support personnel. After modifying
any settings, click Save Settings to save your changes.
Beacon Interval:
Specify a value for the beacon interval. Beacons are packets
sent by an access point to synchronize a wireless network. 100
is the default setting and is recommended.
Transmit Power:
Set the transmit power of the antennas.
RTS Threshold:
Fragmentation:
DTIM Interval:
WMM Capable:
TX Rates:
This value should remain at its default setting of 2347. If
inconsistent data flow is a problem, only a minor modification
should be made.
The fragmentation threshold, which is specified in bytes,
determines whether packets will be fragmented. Packets
exceeding the 2346 byte setting will be fragmented before
transmission. 2346 is the default setting.
Set the interval for DTIM. A Delivery Traffic Indication Message
(DTIM) is a countdown informing clients of the next window
for listening to broadcast and multicast messages. The default
interval is 3.
WMM (Wi-Fi Multimedia) is a QoS (Quality of Service) system
for your wireless network. Enable this option to improve
the quality of video and voice applications for your wireless
clients.
Select the basic transfer rates based on the speed of
wireless adapters on your wireless network. It is strongly
recommended to keep this setting to Auto.

Short GI:
HT 20/40 Coexistence:
Check this box to reduce the guard interval to 400 ns. This can
increase the throughput rate provided that the delay spread
of the connection is also low. However, it can also increase
error rate in some installations, due to increased sensitivity to
radio-frequency reflections. Select the option that works best
for your installation.
Enable this option to reduce interference from other
wireless networks in your area. If the channel width
is operating at 40 MHz and there is another wireless
network’s channel over-lapping and causing interference,
the router will automatically change to 20 MHz.

Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the DWR-755. Read the
following descriptions if you are having problems. The examples below are illustrated in Windows® XP. If you have a different
operating system, the screenshots on your computer will look similar to the following examples.
1. Why can’t I access the web-based configuration utility?
When entering the IP address of the D-Link router (192.168.0.1 for example), you are not connecting to a website nor do you
have to be connected to the Internet. The device has the utility built-in to a ROM chip in the device itself. Your computer must
be on the same IP subnet to connect to the web-based utility.
• Make sure you have an updated Java-enabled web browser. We recommend the following:
- Microsoft Internet Explorer® 6.0 and higher
- Mozilla Firefox 3.0 and higher
- Google™ Chrome 2.0 and higher
- Apple Safari 3.0 and higher
• Verify physical connectivity by checking for solid link lights on the device. If you do not get a solid link light, try using a
different cable or connect to a different port on the device if possible. If the computer is turned off, the link light may not be
on.
• Disable any Internet security software running on the computer. Software firewalls such as Zone Alarm, Black Ice, Sygate,
Norton Personal Firewall, and Windows® XP firewall may block access to the configuration pages. Check the help files included
with your firewall software for more information on disabling or configuring it.
D-Link DWR-755 User Manual

Section 5 - Troubleshooting
• Configure your Internet settings:
• Go to Start > Settings > Control Panel. Double-click the Internet Options Icon. From the Security tab, click
the button to restore the settings to their defaults.
• Click the Connection tab and set the dial-up option to Never Dial a Connection. Click the LAN Settings button.
Make sure nothing is checked. Click OK.
• Go to the Advanced tab and click the button to restore these settings to their defaults. Click OK three times.
• Close your web browser (if open) and open it.
• Access the web management. Open your web browser and enter the IP address of your D-Link router in the address bar. This
should open the login page for your web management.
• If you still cannot access the configuration, unplug the power to the router for 10 seconds and plug back in. Wait about 30
seconds and try accessing the configuration. If you have multiple computers, try connecting using a different computer.
2. What can I do if I forgot my password?
If you forgot your password, you must reset your router. Unfortunately this process will change all your settings back to the
factory defaults.
To reset the router, locate the reset button (hole) on the rear panel of the unit. With the router powered on, use a paperclip
to hold the button down for 10 seconds. Release the button and the router will go through its reboot process. Wait about 30
seconds to access the router. The default IP address is 192.168.0.1. When logging in, the username is admin and leave the
password box empty.

3. Why can’t I connect to certain sites or send and receive emails when connecting through my router?
If you are having a problem sending or receiving email, or connecting to secure sites such as eBay, banking sites, and Hotmail,
we suggest lowering the MTU in increments of ten (Ex. 1492, 1482, 1472, etc).
To find the proper MTU Size, you’ll have to do a special ping of the destination you’re trying to go to. A destination could be
another computer, or a URL.
• Click on Start and then click Run.
• Windows® 95, 98, and Me users type in command (Windows® NT, 2000, XP, Vista®, and 7 users type in cmd) and
press Enter (or click OK).
• Once the window opens, you’ll need to do a special ping. Use the following syntax:
ping [url] [-f] [-l] [MTU value]
Example: ping yahoo.com -f -l 1472
D-Link DWR-755 User Manual
101
Section 5 - Troubleshooting
You should start at 1472 and work your way down by 10 each time. Once you get a reply, go up by 2 until you get a fragmented
packet. Take that value and add 28 to the value to account for the various TCP/IP headers. For example, lets say that 1452 was the
proper value, the actual MTU size would be 1480, which is the optimum for the network we’re working with (1452+28=1480).
Once you find your MTU, you can now configure your router with the proper MTU size.
To change the MTU rate on your router follow the steps below:

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 public access wireless networks. Strictly adhering to the IEEE standard, the D-Link
wireless family of products will allow you to securely access the data you want, when and where you want it. You will be able
to enjoy the freedom that wireless networking delivers.
A wireless local area network (WLAN) is a cellular computer network that transmits and receives data with radio signals instead of
wires. Wireless LANs 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.
Under many circumstances, it may be desirable for mobile network devices to link to a conventional Ethernet LAN in order to
use servers, printers or an Internet connection supplied through the wired LAN. A Wireless router is a device used to provide
this link.

What is Wireless?
Wireless or Wi-Fi technology is another way of connecting your computer to the network without using wires. Wi-Fi uses radio
frequency to connect wirelessly, so you have the freedom to connect computers anywhere in your home or office network.
Why D-Link Wireless?
D-Link is the worldwide leader and award winning designer, developer, and manufacturer of networking products. D-Link
delivers the performance you need at a price you can afford. D-Link has all the products you need to build your network.
How does wireless work?
Wireless works similar to how cordless phone work, through radio signals to transmit data from one point A to point B. But
wireless technology has restrictions as to how you can access the network. You must be within the wireless network range area
to be able to connect your computer. There are two different types of wireless networks Wireless Local Area Network (WLAN),
and Wireless Personal Area Network (WPAN).
Wireless Local Area Network (WLAN)
In a wireless local area network, a device called an Access Point (AP) connects computers to the network. The access point has
a small antenna attached to it, which allows it to transmit data back and forth over radio signals. With an indoor access point
as seen in the picture, the signal can travel up to 300 feet. With an outdoor access point the signal can reach out up to 30 miles
to serve places like manufacturing plants, industrial locations, college and high school campuses, airports, golf courses, and
many other outdoor venues.
Wireless Personal Area Network (WPAN)
Bluetooth is the industry standard wireless technology used for WPAN. Bluetooth devices in WPAN operate in a range up to
30 feet away.

Compared to WLAN the speed and wireless operation range are both less than WLAN, but in return it doesn’t use nearly as
much power which makes it ideal for personal devices, such as mobile phones, PDAs, headphones, laptops, speakers, and other
devices that operate on batteries.
Who uses wireless?
Wireless technology as become so popular in recent years that almost everyone is using it, whether it’s for home, office, business,
D-Link has a wireless solution for it.

Where is wireless used?
Wireless technology is expanding everywhere not just at home or office. People like the freedom of mobility and it’s becoming
so popular that more and more public facilities now provide wireless access to attract people. The wireless connection in public
places is usually called “hotspots”.
Using a D-Link Cardbus Adapter with your laptop, you can access the hotspot to connect to Internet from remote locations
like: airports, hotels, coffee shops, libraries, restaurants, and convention centers.
Wireless network is easy to setup, but if you’re installing it for the first time it could be quite a task not knowing where to start.
That’s why we’ve put together a few setup steps and tips to help you through the process of setting up a wireless network.
Tips
Here are a few things to keep in mind, when you install a wireless network.
Centralize your router or Access Point
Make sure you place the router/access point in a centralized location within your network for the best performance. Try to
place the router/access point as high as possible in the room, so the signal gets dispersed throughout your home. If you have
a two-story home, you may need a repeater to boost the signal to extend the range.
Eliminate Interference
Place home appliances such as cordless telephones, microwaves, and televisions as far away as possible from the router/access
point. This would significantly reduce any interference that the appliances might cause since they operate on same frequency.
Security
Don’t let you next-door neighbors or intruders connect to your wireless network. Secure your wireless network by turning on
the WPA or WEP security feature on the router. Refer to product manual for detail information on how to set it up.

Appendix A - Wireless Basics
Wireless Modes
There are basically two modes of networking:
• Infrastructure – All wireless clients will connect to an access point or wireless router.
• Ad-Hoc – Directly connecting to another computer, for peer-to-peer communication, using wireless network
adapters on each computer, such as two or more DWR-755 wireless network Cardbus adapters.
An Infrastructure network contains an Access Point or wireless router. All the wireless devices, or clients, will connect to the
wireless router or access point.
An Ad-Hoc network contains only clients, such as laptops with wireless cardbus adapters. All the adapters must be in Ad-Hoc
mode to communicate.

Check your IP address
After you install your new D-Link adapter, by default, the TCP/IP settings should be set to obtain an IP address from a DHCP
server (i.e. wireless router) automatically. To verify your IP address, please follow the steps below.
Click on Start > Run. In the run box type cmd and click OK. (Windows® 7/Vista® users type cmd in the Start Search box.)
At the prompt, type ipconfig and press Enter.
This will display the IP address, subnet mask, and the
default gateway of your adapter.
If the address is 0.0.0.0, check your adapter installation,
security settings, and the settings on your router.
Some firewall software programs may block a DHCP
request on newly installed adapters.

Statically Assign an IP address
If you are not using a DHCP capable gateway/router, or you need to assign a static IP address, please follow the steps below:
Step 1
Windows® 7 Click on Start > Control Panel > Network and Internet > Network and Sharing Center.
Windows Vista® - Click on Start > Control Panel > Network and Internet > Network and Sharing Center > Manage Network
			Connections.
Windows® XP Click on Start > Control Panel > Network Connections.
Windows® 2000 - From the desktop, right-click My Network Places > Properties.
Step 2
Right-click on the Local Area Connection which represents your network adapter and select Properties.
Step 3
Highlight Internet Protocol (TCP/IP) and click Properties.
Step 4
Click Use the following IP address and enter an IP address that is on the same subnet as your network or the LAN IP address
on your router.
Example: If the router´s LAN IP address is 192.168.0.1, make your IP address 192.168.0.X
where X is a number between 2 and 99. Make sure that the number you choose is not
in use on the network. Set the Default Gateway the same as the LAN IP address of your
router (I.E. 192.168.0.1).
Set Primary DNS the same as the LAN IP address of your router (192.168.0.1). The
Secondary DNS is not needed or you may enter a DNS server from your ISP.
Step 5
Click OK twice to save your settings.
