Note for Latin America: 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.
• If your router or access point does not broadcast its network name (SSID), follow the instructions that
came with your product to enter your wireless network name manually.
• If your router or access point has security enabled, determine the kind of security it is using and any
required password or passphrase for connection. Then make sure to enter the exact WEP key or WPA
passphrase correctly.
• Check if your computer is restricting the available wireless channels. If so, verify that your wireless
access point is using one of the usable channels and change to a usable channel, if necessary.
• If you cannot connect your product to a device using Wi-Fi Direct, you may have exceeded the
maximum number of devices connected to your product (8). Print a network status sheet or access
Web Config on the browser for your device and check the number of connected devices. If 8 devices
are already connected, disconnect a device by deleting the product's SSID from the Wi-Fi screen of
that device. If fewer than 8 devices are connected, check the accuracy of your other network settings,
move your device closer to your product, and try connecting again.
• If you are using a Wi-Fi Direct connection that suddenly disconnects, the Wi-Fi direct password on
your device may have been changed. If necessary, delete the existing DIRECT-xxxxxxxx connection
settings from your device and enter a new password. See your device documentation for instructions.
