Troubleshooting Wireless LAN
I cannot use the Wireless LAN functionality
Check if the
Wireless LAN
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.

The 2.4 GHz bandwidth used by wireless LAN compatible devices is also used by other various devices. Although technologies to minimize
interference from other devices that uses the same bandwidth are employed on wireless LAN compatible devices, such interference may
cause lower communication speed, narrower communication range, or broken wireless connections.
!
The communication speed varies depending on the distance between communication devices, existence of obstacles between such devices,
the device configuration, the radio conditions, and the software in use. In addition, communications may be cut off depending on the radio
conditions.
!
The communication range varies depending on the actual distance between communication devices, existence of obstacles between such
devices, the radio conditions, the ambient environment that includes existence of walls and materials of such walls, and the software in use.

Deploying IEEE 802.11b and IEEE 802.11g products on the same wireless network may reduce the communication speed due to radio
interference. Taking this into consideration, the IEEE 802.11g products are designed to reduce the communication speed to ensure
communications with IEEE 802.11b products.
When the communication speed is not as fast as expected, changing the wireless channel on the access point may increase the
communication speed.
