General notes on using the wireless LAN function
❑
In some countries, using WLAN products may be restricted by the local regulations (e.g. limited number of channels).
Before activating the WLAN function, read the wireless LAN regulations guide carefully.
❑
The IEEE 802.11a standard and the IEEE 802.11n standard are not available on ad-hoc networks.
❑
The 2.4 GHz band used by wireless LAN compatible devices is also used by other various devices. Although technologies
to minimize interference from other devices that use the same band are employed on wireless LAN compatible devices,
such interference may cause lower communication speed, narrower communication range, or broken wireless
connections.
❑
The communication speed and range may vary depending on the following conditions:
❑
Distance between communication devices
❑
Existence of obstacles between devices
❑
Device configuration
❑
Radio conditions
❑
Ambient environment that includes existence of walls and materials of such walls
❑
Software in use
❑
Communications may be cut off depending on radio conditions.
❑
Actual communication speed may not be as fast as the one displayed on your computer.
❑
Deploying WLAN products compliant with different standards that use the same band on the same wireless network may
reduce the communication speed due to radio interference. Taking this into consideration, WLAN products are designed
to reduce the communication speed to ensure communications with another WLAN product if it is compliant with a
different standard that uses the same band. When the communication speed is not as fast as expected, changing the
wireless channel on the access point may increase the communication speed.
