Where do I find my WEP key or WPA passphrase?
To find the WEP key or WPA passphrase for the wireless network, view the security settings on the access point or
wireless router. Most access points have a Web page that can be accessed using a Web browser.
You can also check the manual that came with your access point or router. If your access point or router is using the
default settings, you can find the information in the manual. If someone else set up your network for you, that person
or company may...

How do I find out what type of security my network is using?
You must know the WEP key or WPA passphrase and the type of security (WEP, WPA, or WPA2) used on the wireless
network. To obtain this information, see the documentation that came with your wireless access point (wireless router),
see the Web page associated with the wireless access point, or consult your system support person.
Note: The WEP key or WPA passphrase is not the same as the password for the wireless access point. The password
allows...

Scenario 2: Wireless network with Internet access

All computers and printers connect to the network using a wireless access point or wireless router.
The wireless access point connects the network to the Internet through a DSL or cable modem.
Internet
Scenario 3: Wireless network with no Internet access

Computers and printers connect to the network using a wireless access point.
The network has no connection to the Internet.
Scenario 4: Computer connected wirelessly to a printer without Internet...

The installation cable connects to a rectangular USB port on the installing computer and the square USB port on the
printer.
How do I attach the installation cable?
The installation cable attaches to a USB port on the computer and to the square connector on the back of the printer.
This connection allows you to configure the printer for a networked or locally attached installation.
1Attach the large, rectangular connector to any USB port on your computer. USB ports may be on the front or the
back of the...

How can I improve wireless signal strength?
A common reason wireless printers fail to communicate over a network is poor wireless signal quality. If the signal is
too weak, too distorted, or blocked by an object, it cannot carry information between the access point and the printer.
To determine if the printer is receiving a strong signal from the access point, print a network setup page. The Quality
field indicates the relative strength of the wireless signal the printer is receiving. Drops in signal...

How can I make sure my computer and printer are connected to the same wireless
network?
If the printer is not on the same wireless network as the computer, then you will not be able to print wirelessly. The
SSID of the printer must match the SSID of the computer, if the computer is already connected to the wireless network.
For Windows users
1Obtain the SSID of the network that the computer is connected to:
aType the IP address of your access point (wireless router) in the address field of your Web...

In Mac OS X version 10.4 or earlier

From the Finder, navigate to:
Applications > Internet Connect > AirPort
The SSID of the network that the computer is connected to is displayed in the Network menu.
2Write down the SSID.
For Macintosh users with an access point
1Type the IP address of the access point in the address field of your Web browser and continue to step 2.
If you do not know the IP address of the access point, then do the following:
aFrom the Apple menu, navigate to:
System Preferences >...

Routers with security capabilities may allow filtering of MAC addresses on networks. This allows a managed list of
devices to access the network, identified by their MAC addresses. MAC address filtering can help prevent access on
the network from unwanted devices, such as from intruders on a wireless network. MAC address filtering can also
prevent legitimate access if you forget to add a new device to the routers list of allowed addresses. If your network
uses MAC address filtering, be sure to add the...

What is TCP/IP?
Networks are able to function because computers, printers, and other devices are able to send data to each other,
either through cables or by using wireless signals. This transfer of data is made possible by sets of data transmission
rules called protocols. A protocol can be thought of as a language, and like a language, it has rules allowing participants
to communicate with each other.
Different types of networks use different protocols, but Transmission Control Protocol/Internet...
