Why is the data transfer speed slow?
 The wireless LAN data transfer speed is affected by distance and obstructions between devices and access points.
Other factors include device configurations, radio conditions, and software compatibility. To maximize the data
transfer speed, move your computer away from obstructions or closer to any access point you may be using.

If you are using a wireless LAN access point, the device may be temporarily overloaded depending on the number of
other devices communicating via the access point.
 If your access point interferes with other access points, change the access point channel. See your access point
instructions for more information.
Why is the communication speed interrupted or slowed down when MPEG2 data is transferred?
The typical effective data transfer speed via an access point is 4-5 Mbps when adhering to the IEEE 802.11b standard.
High-rate stream transfers with MPEG2 data may lower this rate.
How do I avoid data transfer interruptions?
 Data transfer interruptions may occur with large files or use of microwaves and cordless telephones when
connected to an access point.

Move the computer closer to the access point.

Make sure the access point connection is intact.
