Troubleshooting
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 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.
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.
❑
Change the access point channel. See your access point manual 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, see connectivity information contained in your access point instructions.
When I change the encryption key, the network connection stops. What should 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 re-enter the key on both computers so the key matches.
