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.
