If this did not solve the issue, try the next solution.
Solution 3: Enter your network name (SSID) carefully
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 28
Cause: If you had manually entered your network name (SSID), you must have
entered it incorrectly.
If this did not solve the issue, try the next solution.
Solution 4: Disable MAC address filtering on your wireless router
Solution: Disable MAC address filtering on your wireless router until the product
has successfully connected to your network. If you re-enable MAC address filtering
on your wireless router, make sure the MAC address of the product is on the list of
acceptable MAC addresses.
Cause: The setting for MAC address filtering was enabled on your wireless router.
Invalid WEP key during wireless setup
Solution: During the wireless setup process, you might have entered the WEP key
incorrectly. Some wireless routers provide up to four WEP keys. The product 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.
Cause: If you were using WEP security, you must have entered the WEP key
incorrectly during the wireless setup process.
Invalid passphrase during wireless setup
Solution: Run the wireless setup process again and enter the correct passphrase.
The passphrase is case-sensitive.
Cause: During the wireless setup process, you had entered the WPA passphrase
incorrectly.
