Troubleshooting and support

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 10

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 to scroll to the bottom of the list. Infrastructure entries are listed first, ad hoc last.

Cause: An Ethernet cable is connected to the HP All-in-One.

Solution: When an Ethernet cable is plugged into the HP All-in-One, the wireless radio turns off. Unplug the Ethernet cable.

Cannot connect to network during setup

Cause: The equipment is not turned on.

Solution: Turn on the networked devices, such as the wireless router for an infrastructure network, or the computer for an ad hoc network. For more information on how to turn on the wireless router, see the documentation that came with your wireless router.

Cause: The HP All-in-One is not receiving a signal.

Solution: Move the wireless router and the HP All-in-One closer together. Then run the wireless setup again.

For more information, see:

“Integrated wireless WLAN 802.11 network setup” on page 9

Cause: If you manually entered your network name (SSID), you might have entered it incorrectly.

Solution: Run the wireless setup process again and enter your network name (SSID) carefully. Remember that the SSID is case-sensitive.

For more information, see:

“Connect to an integrated wireless WLAN 802.11 network” on page 10

Cause: The setting for MAC address filtering might be enabled on your wireless router.

Solution: Disable MAC address filtering on your wireless router until the HP All-in-One has successfully connected to your network. If you re-enable MAC address filtering on your wireless
