I see the message Network Connection Failed when I install my product's wireless network software. What should I do?

• Check the following:
  • Make sure that your wireless router or access point is set to use one of the supported security settings: None, WEP 64, WEP 128, or WPA-PSK.
  • If security is enabled for your wireless router or access point, make sure that you entered the correct security key or passphrase.
  • If there are any access restrictions (such as MAC address filtering) set on the wireless router or access point, register the printer's MAC address on the router or access point. Print a Network Status Sheet to obtain the MAC address. Then see your router or access point's documentation for instructions.
  • Disable any settings (such as AP Isolation, Client Isolation, or Privacy Separator) on your wireless router or access point that would prevent wireless devices from communicating with each other.
