Solving wireless (802.11) problems

The following sections provide assistance if you are encountering problems connecting the HP Officejet/Officejet Pro
device to your wireless network. First, follow the suggestions provided in the Basic troubleshooting section. If you are
still encountering problems, follow the suggestions provided in the Advanced troubleshooting section.
After you resolve any problems and have connected the HP device to your wireless network, complete the following
steps:
Windows
Place the Starter CD into the computer and run the software installation program again. If you are using a computer
running Windows, select either Install Network/Wireless Device or Add a Device when prompted.
Mac OS
Open the HP Device Manager, located in the Dock. (HP Device Manager is also located in the Hewlett-Packard
folder in the Applications folder on your computer.) Select Setup Assistant or Network Setup Assistant from the
Information and Settings list, and then follow the onscreen instructions.

Basic troubleshooting

If you are encountering problems using your
HP Officejet/Officejet Pro device over a network, try the
following suggestions in the order listed:
1. Make sure the wireless (802.11) light is turned on
If the blue light near the HP device's control panel is not
lit, wireless capabilities might not have been turned on.
To turn on wireless, press the wireless button
(located near the wireless light) once to turn on wireless
capabilities. Or press the
HP device's control panel, select Network,
select Wireless Radio, and then select On.
NOTE: If your HP device supports Ethernet networking,
make sure that an Ethernet cable has not been
connected to the device. Connecting an Ethernet cable
turns off the HP device's wireless capabilities.
2. Check the wireless signal strength
If the strength of the signal for your wireless network or
computer is weak or if there is interference on the
wireless network, the HP device might not be able to
detect the signal. To determine the strength of the
wireless signal, print a Wireless Network Test from the
HP device control panel. (For more information,
see "Run the Wireless Network Test" on page 6.
If the Wireless Network Test indicates the the signal is
weak, try moving the HP device closer to the wireless
router.

The following tips might help reduce the chances for
interference in a wireless network:
• Keep the wireless devices away from large metal
objects, such as filing cabinets, and other
electromagnetic devices, such as microwaves and
cordless telephones, as these objects can disrupt
radio signals.
• Keep the wireless devices away from large masonry
structures and other building structures as these
objects can absorb radio waves and lower signal
strength.
3. Restart components of the wireless network
Turn off the router and the HP device, and then turn
them back on in this order: router first, and then the
HP device. If you still are unable to connect, turn off
the router, HP device, and your computer, and then
turn them back on in this order: router first, then the
HP device, and finally the computer. Sometimes, turning
off the power and then turning it back on will recover a
network communication issue.
4. Run the Wireless Network Test
For wireless networking issues, run the Wireless
Network Test from the HP device control panel:
a. On the HP device's control panel display,
touch (Setup).
b. Touch Network, and then touch Wireless Network
Test.
If a problem is detected, the printed test report will
include recommendations that might help solve the
problem.
