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.
