Troubleshooting Networks
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 in the ON position or the Wireless LAN PC Card is properly
inserted. See Inserting PC Cards for more information.

Make sure power to the access point is on.

Make sure the encryption key is correct.
Why can't I gain access to the Internet?

If you are using a Wireless LAN PC Card, make sure it is properly inserted into the PC Card slot. For more
information, see
Inserting PC Cards.

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 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.

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.
