■ Make sure there aren’t any access restrictions (such as MAC address filtering) set on
the wireless router. If access restrictions are set, register the product’s MAC address on
the router. To obtain the MAC address, print a Network Status Sheet (see page 31).
Then see your router’s manual for instructions.

WPA passphrase correctly. Contact your router manufacturer for assistance.
