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 PC Card (purchased separately) is properly inserted.
 Make sure power to the access point is on.
 Make sure the access point is displayed in the Available networks window.
1. From the Start menu, click Control Panel, Network and Internet Connections, and then Network
Connections.
2. Right-click Wireless Network Connection, and select Properties. The Wireless Network Connection
Properties dialog box appears.
3. Select the Wireless Networks tab, and make sure the access point is displayed in the Available
networks box. If it is not displayed, see
To connect to an existing wireless network for more information.
 Make sure the encryption key is correct.
Why can't I access the Internet?
 Make sure the Wireless LAN PC Card (purchased separately) is properly inserted into the PC Card slot.
 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.
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.
