My product cannot connect to a wireless router or access point. What should I do?

• If your scanner has trouble finding or connecting to a wireless router, try these solutions:

   

  • If you did not successfully connect to a network while installing your product software, select the link at the end of this topic and follow the steps in "Manually Connecting to a Wi-Fi Network". If you are still unable to connect to a network, try the other solutions in this topic.
  • If you are connecting the scanner via Wi-Fi Protected Setup (WPS), make sure you activate WPS on your scanner within 2 minutes of activating WPS discovery mode on the router by pressing the WPS button or enabling the WPS setting in your router firmware.
  • Make sure to place your scanner within contact range of your router. Avoid placing your scanner 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 is operating correctly by connecting to it from your computer or another device.
  • You may need to disable the firewall and any anti-virus software on your wireless 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 scanner's MAC address to your router's address list. To obtain your scanner's MAC address, check the label on the back of your scanner. Then follow the instructions in your router or access point documentation to add the address to the list.
  • If your router does not broadcast its network name (SSID), follow the instructions that came with your scanner to enter your wireless network name manually.
  • If your router 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.
  • The scanner may not be able to communicate with a computer with multiple network interfaces. Disable all network interfaces except for the interface connected to the scanner.
  • Enable the DHCP function on the access point or router.
  • Check that the scanner's IP address is set correctly.
