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 process again.
For more information, see:
"Integrated wireless WLAN 802.11 network setup" on page 8
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 9
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
router, make sure the MAC address of the HP All-in-One is on the list of acceptable MAC
addresses.
Invalid WEP key during wireless setup
Cause: If you are using WEP security, you might have entered the WEP key incorrectly during
the wireless setup process.
Solution: During the wireless setup process, you might have entered the WEP key incorrectly.
Some wireless routers provide up to four WEP keys. The HP All-in-One uses the first WEP key
(selected by the wireless router as the default WEP key). Run the wireless setup process again
and be sure to use the first WEP key provided by the wireless router. Enter the WEP key exactly
as it appears in the wireless router settings. The WEP key is case sensitive.
If you do not know the WEP key, see the documentation that came with your wireless router for
information on how to access the router's Embedded Web Server. You can find the WEP key
by logging onto the router's Embedded Web Server using a computer on the wireless network.
Invalid passphrase during wireless setup
Cause: During the wireless setup process, you might have entered the WPA passphrase
incorrectly.
Solution: Run the wireless setup process again and enter the correct passphrase. The
passphrase is case-sensitive.
The Printer Not Found screen appears during installation
Cause: An anti-virus or anti-spyware application is preventing the HP All-in-One from
accessing your computer.
