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.
1 From the Start menu, click Control Panel, Network and Internet
Connections. The Network and Internet Connections window
appears.
2 Click Network Connections. The Network Connections window
appears.
3 Check the connection status.
❑
Change the access point channel. See your access point instructions for more
information.
Can I connect to a IEEE 802.11a device?
Computers with built-in wireless LAN support the IEEE 802.11b standard only.
Devices connecting to a wireless LAN using the IEEE 802.11a standard cannot
connect to devices using the IEEE 802.11b standard.
What are channels?
Wireless LAN communication occurs on divided frequency bands known as
channels. Third-party wireless LAN access point channels may be preset to
different channels from Sony devices.
If you are using a wireless LAN access point, refer to connectivity information
contained in your access point instructions.
