If one or more wireless devices only
conforming to IEEE802.11b exist in a
range where radio waves can be radiated
to a connected wireless LAN access point
conforming to IEEE802.11g, the
communication speed for IEEE802.11g
decreases. If a wireless device only
conforming to IEEE802.11b connects to
another access point, reach of radio
waves to the access point influences the
communication speed.
If a microwave oven is used in an area
where communication with 2.4 GHz
wireless LAN device occurs, the
communication speed and distance of the
LAN device may be reduced. It is
recommended not to use microwave
ovens near 2.4 GHz wireless LAN
devices.
Concurrent communication of 2.4 GHz
wireless LAN and Bluetooth devices may
decrease the communication speed
and/or distance of devices of each type.
Increase in the number of PCs connected
to a single wireless LAN access point
may cause the transmission speed per
PC to decrease.
