D-Link Router to an AT&T DSL Modem
With an always-on, high-speed Internet connection like DSL
(Digital Subscriber Line), a router is a prudent addition to your local
network.
It filters out unauthorized access to your network, which
prevents an intruder from accessing computers that are connected to that
network.
However, getting your computers, routers and modems on the
same page may not work right "out of the box."
There are a few things you must be aware of, especially if
this is a wireless network.
Unplug your DSL modem and D-Link router.
In order for the network to properly recognize its devices,
these devices must be attached in a specific order.
Plug in your DSL modem's power cord.
There is usually no power button on a modem.
Simply plugging in its electrical cable will turn it on.
Give your DSL modem a couple minutes to re-establish its
connection to AT&T's network before taking any further action.
Plug in your D-Link router's power cord.
Like the DSL modem, this router will probably not have a power
switch; simply plug in the power cable, and it turns on.
Let the D-Link router sit for a couple minutes while it
establishes its connection to the DSL modem and AT&T's network.
Physically attach your computer to the router with an
Ethernet cable.
Even if the router and modem are wireless, a physical
connection must be established to properly configure the router.
If this is not a wireless network, then your setup procedure
is essentially complete.
To access a D-Link router on your network, open an Internet
browser and navigate to the 192.168.0.1 address.
This will bring you to your D-Link router's interface.
The default User Name is "admin" (without the
quotes), and there is no password.
Enter the User Name
and click the "Log In" button. This will bring you to the Setup
window.
Refer to your D-Link router's documentation for changing the
default password (highly recommended) and forwarding ports.
If this is a wireless network, you have a couple further
steps.
First, change your network's SSID (Service Set Identifier)
title, so that you can recognize it when other wireless networks are nearby.
Also, choose your wireless encryption and passphrase. WPA2
(Wi-Fi Protected Access 2) is a solid option.
Specific instructions depend on your model of D-Link router;
so refer to your documentation (which can usually be found at the
manufacturer's website if you do not have it on hand).
Disconnect the Ethernet cable from your computer.
Your new wireless network should be visible with your
computer's wireless adapter.
Windows and OS X will notify you of networks in range when
your adapter is active.
Connect to the one with your SSID, and enter the passphrase.

Wireless Network D-Link
If you have a D-link wireless network, your computer is
susceptible to outside intruders unless you take preventive measures to prevent
intrusion.
There are some important settings that you need to change
within your D-link control panel to add an extra measure of security.
By changing these settings, the intruders will have no other
choice but to choose another computer to attack.
Type the router IP address, "192.168.0.1", into your Internet
browser.
Press "Enter" on your keyboard.
Enter your username and password to log into the D-link
configuration panel.
By default, the username is "Admin" with a blank
password field.
To prevent outsiders from being able to access your D-link
router's configuration panel, change the username and password to something
more secure.
This can be done by selecting "Tools" from the
menu and selecting "Admin."
Select "Administration Settings" and enter your
new username and password.
Save your changes by clicking "Apply."
Enter the IP
addresses for the computers you want to give access to your router.
You can do this by clicking the "DHCP" link
underneath the "Home" tab. Click "Apply" to save the IP
addresses.
Select the "Wireless" link underneath the
"Home" tab.
Enter a name in the "SSID" field to identify your
wireless network.
Choose "WPA" for your "Security"
option.
WPA will provide the highest level of security for your
wireless network. Create a WPA password to access your wireless network.
For maximum security, enter a combination of numbers,
letters, and symbols.
Store your password in a safe place in case you ever forget
it.
Click "Apply" to save your settings.
Install a software firewall program on your computer to add
an additional measure of security for your wireless network.
A few of the popular firewall programs available
are Norton Antivirus, McAfee and Zone Alarm.
