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
To insert a PC Card
for more information.
Make sure power to the access point is on.
Make sure the access point is displayed in the
Available networks
window.

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 program 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.
