3. Check 4 Check the wireless router's security protocol (encryption method) settings.

   If the wireless router is set to communicate using the IEEE802.11n standard only and encryption is set to TKIP, change the encryption standard to something other than TKIP or change the communication standard, and then redo the wireless connection settings.

   If the encryption standard is set to TKIP, IEEE802.11n cannot be used as the communication standard.

   For details on changing the wireless router settings, see the wireless router manual or contact its manufacturer.
