Wireless setup troubleshooting

This section addresses problems you might encounter setting up a network.
During wireless network setup you do not see the SSID (network name)
displayed
Cause: Your wireless router is not broadcasting its network name (SSID) because the
Broadcast SSID option is turned off.
Solution: Access the router's Embedded Web Server and turn on the Broadcast SSID option.
See the user guide that came with your wireless router for information on how to access the
Embedded Web Server and check the Broadcast SSID setting.
For more information, see:
"Connect to an integrated wireless WLAN 802.11 network" on page 9
Cause: The wireless router (infrastructure) or computer (ad hoc) is too far from the
HP All-in-One or there is interference.
Solution: In order to establish a good signal between the HP All-in-One and wireless router
(infrastructure) or computer (ad hoc), you might have to experiment a bit. Assuming the
equipment is functioning properly, try doing the following things separately or in combination:
• If there is a long distance between your computer or wireless router and the HP All-in-One,
move them closer together.
• If there are metal objects (such as a metal bookcase or refrigerator) in the transmission
path, clear the path between the HP All-in-One and the computer or wireless router.
• If a cordless telephone, microwave, or other device that emits radio signals transmitting at
2.4 GHz is nearby, move it farther away to reduce radio interference.
• If your computer or wireless router is near an external wall, move them away from the wall.
Cause: Your network name (SSID) may be at the bottom of the SSID list that is displayed
when you install the HP All-in-One on a wireless network.
Solution: Press
hoc last.
Weak signal

router, you might have to experiment a bit. Assuming the equipment is functioning properly, try
doing the following things separately or in combination:
• If there is a long distance between your computer or wireless router and the HP All-in-One,
move them closer together.
• If there are metal objects (such as a metal bookcase or refrigerator) in the transmission
