Product Cannot Connect to a Wireless Router or Access Point
If your product has trouble finding or connecting to a wireless router or access point, try these solutions:
• If you are connecting the product via Wi-Fi Protected Setup (WPS) and the Wi-Fi icon on your
product's LCD screen is not lit or does not appear, make sure you select one of the WPS options from
the product control panel within 2 minutes of pressing the WPS button on your router.
• Make sure to place your product within contact range of your 2.4 GHz router or access point. Avoid
placing your product near a microwave oven, 2.4 GHz cordless phone, or large metal object, such as a
filing cabinet.
Note: If you are using a 5 GHz wireless router, set the router to operate in dual band (2.4 GHz and
5 GHz) mode. If your router uses a single network name (SSID) for both the 2.4 GHz and 5 GHz band,
give each band its own network name (SSID) instead, such as Home Network 2.4 GHz and Home
Network 5 GHz. See your router documentation or contact your internet service provider for
instructions.
• Verify that your router or access point is operating correctly by connecting to it from your computer or
another device.
• Print a network connection report and check the codes and messages on the report to help determine
the cause of the problem.
• You may need to disable the firewall and any anti-virus software on your wireless router or access
point.
• Try restarting your router following the instructions in your router documentation.
Note: If you are reading these instructions online, you will lose your Internet connection when you
restart your router.
• Check to see if access restrictions, such as MAC address filtering, are set on the router or access
point. If access restrictions are set, add your product's MAC address to your router's address list. To
obtain your product's MAC address, print a network status sheet. Then follow the instructions in your
router or access point documentation to add the address to the list.
