Troubleshooting Wireless LAN
if you cannot use the Wireless LAN function, make sure the wireless switch is turned on before checking the following points.
The Wireless LAN Access Point and my computer cannot communicate
❑ Check if the power of the Access Point is turned on.
❑ Check if the Access Point is displayed in the View Available Networks list.
(Right-click the network icon in the taskbar displaying Wireless Network Connection. Click the View Available Wireless
Networks link.)
If the Access Point is displayed, select the Access Point and click the Connect button.
If the Access Point is not displayed, click the Refresh Network List and create a network (See Communicating with an Access
Point (infrastructure) (page 38)).
❑ Connection availability is affected by distance and obstructions. You may need to move your computer away from obstructions
or nearer to any Access Point you may be using.
The data transfer speed is slow
❑ The maximum communication speed can vary depending on the obstacles or the distance between the communication devices
and the radio waves. Remove the obstacle or make the distance between the Access Point and your machine smaller.
❑ It is possible that your Access Point communicates at the same time with another Access Point. Read the manual of the Access
Point.
❑ If several computers communicate with the same Access Point, the concentration may be too high. Wait a few minutes and try
to access it again.
❑ If a Wireless LAN device using the IEEE 802.11g standard communicates with a device using the IEEE 802.11b standard, it is
normal that the speed is reduced. Devices using the IEEE 802.11g standard are 5 times faster than the ones using the
IEEE 802.11b standard.
