• 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 access point in the

address bar. This should open the login page for your the web management.

• If you still cannot access the configuration, unplug the power to the access point 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 access point. Unfortunately this process will change all your settings

back to the factory defaults.

To reset the access point, locate the reset button (hole) on the rear panel of the unit. With the access point powered

on, use a paperclip to hold the button down for 5 seconds. Release the button and the access point will go through

its reboot process. Wait about 30 seconds to access the access point. The default IP address is 192.168.0.50. 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 pocket router

(router mode only)?

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).

Note: AOL DSL+ users must use MTU of 1400.

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, and XP 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

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 access point with the proper MTU size.

To change the MTU rate on your access point follow the steps below:

• Open your browser, enter the IP address of your access point (192.168.0.50) and click

OK.

• Enter your username (admin) and password (blank by default). Click

OK

to enter the web configuration

page for the device.

• Click on

Setup

and then click

Manual Configure.

• To change the MTU enter the number in the MTU field and click

Save Settings

to save your settings.

• Test your email. If changing the MTU does not resolve the problem, continue changing the MTU in

increments of ten.

Appendix A - 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 Access point 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.

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.
