Frequently asked questions
Why can't my computer connect to a wireless LAN access point?
 Connection availability is affected by distance and obstructions. You may need to move your computer away from
obstructions or closer to any access point you may be using.

Make sure the Wireless LAN switch on the computer is on.

Make sure power to the access point is on.

Make sure the access point is displayed in the Available networks window. For more information, see To connect to
a wireless network.
 Make sure the encryption key is correct.
Why can't I access the Internet?
 Check the access point settings. Refer to the instructions supplied with the access point.
 Make sure your computer and the access point are connected to one another.

Move your computer away from obstructions or closer to any access point you may be using.

Make sure your computer is properly configured for Internet access.
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 how many
other devices are communicated 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 rate via an access point when adhering to the IEEE 802.11b standard is 4-5 Mbps and
IEEE802.11g standard is 10-20 Mbps. High-rate stream transfers with MPEG2 data may lower these rates.
How do I avoid data transfer interruptions?
 When your computer is connected to an access point, data transfer interruptions may occur when using large files
or if the computer is in close proximity to microwaves and cordless telephones.

Move the computer closer to the access point.

Make sure the access point connection is intact. For more information, see Checking your network connection
status.
 Change the access point channel. See your access point instructions for more information.
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.
When I change the encryption key, the network connection stops. What do I do?
Two computers with built-in wireless LAN may loose a peer-to-peer network connection if the encryption key is changed.
You can either change the encryption key back to the original profile or restart both computers.
