7.3 LOCAL AREA NETWORK (LAN) ETHERNET AND WIRELESS LAN (cont’d)
[Restrictions]
1) Not supporting Atheros SuperG and XR.
2) Extended Aironet is not supported.
3) When AdHoc is in use, baud rate will be based on IEEE802.11b.
4) When AES is in use, the connection to AP by Broadcom will be unstable.
This is because Broadcom is equipped with AES based on 802.11Draft.
5) There is no guarantee of proper operation for DSA authentication of EAP-TLS.
Notes
For Both On-board LAN and Wireless LAN Interface
• To open/close Print data port (Port 1024), Status port (Port1025) or Sending/Receiving port (Port 9100),
make sure to close and open the port at intervals of approximately 150ms to 200ms. If you don't have
enough time from closing to opening the port, it may result in double connection.
• If the host requests the connection to the port already connected (Port 1024, Port 1025 or Port 9100), the
printer accepts the request (establishing double connection); however, the printer disconnects the second
connection immediately.
For Wireless LAN Interface
1) Communication range and transmission rates between the host computer and the printer (Wireless LAN
board) may change depending on the operating environment and conditions of radio waves.
2) In Infrastructure mode, the best operating environment and conditions of the radio field strength is Medium
level (50 to 75%) or higher.
3) Communication data may be lost under the inappropriate circumstances for radio waves such as the
mobile computing type of environment and actual operating conditions.
4) When multiple wireless network groups are nearby, the frequency for the channel of each group has to be
5 or higher.
For example: When the channel of Group1 is [1], set the channel of Group2 to [6] or higher.
For On-board LAN Interface
1) Do not connect and disconnect the LAN cable while starting up the printer. Restart the printer with which
you are having a communication error due to connection or disconnection of the LAN cable.
