Troubleshooting Wireless LAN

I cannot use the Wireless LAN function
❑
Check if the Wireless switch is turned on.
The Wireless LAN Access Point and your computer cannot communicate
❑
Check if the Wireless LAN switch is turned on.
❑
Check if the power of the Access Point is turned on.
❑
Check if the Access Point is displayed in the Available networks window.
❑
To check this, click Start and then Control Panel.
❑
Double-click the Network Connections icon.
❑
Right-click the Wireless Network Connection icon and select Properties.
❑
Select the Wireless Networks tab.
❑
Check if the Access Point is displayed in Available networks.
❑
Connection availability is affected by distance and obstructions. You may need to move your computer away from
obstructions or neared 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, the radio waves, the operating system or the software you use. 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 again.
❑
If a Wireless LAN device using the IEEE 802.11g standard communicates with a device using the IEEE 802.11b standard, then
it is normal that the speed reduces.
