## What should I do if I cannot play back movies or audio tracks received via wireless LAN, or their playback is interrupted? Why is the data transfer speed slow?

- Move your VAIO computer away from obstructions, or closer to any access point you may be using.

  Connection capability is affected by distance, obstructions, device configuration, radio wave strength/interference, wall materials, running software, etc.

- If you are using an access point, the device may be temporarily overloaded depending on how many other devices are communicating via the access point.

  Wait for a while and try again.

- Change the channel setting of your access point. By changing the channel, interference on your wireless network may be reduced and data transfer speed may improve.

  If access point channel interference occurs, data transfer speed may be reduced.

- If your access point interferes with other access points, change the access point channel.

  Refer to the manual that came with your access point for more information.

- Make sure that a microwave oven is not operating near your wireless LAN devices.

  The 2.4 GHz frequency band, on which the wireless LAN operates, is used by various devices and apparatus. If you use a microwave oven while communicating via wireless LAN, data transfer rate may slow down, communication range may narrow, or communication may be interrupted.

- Make sure Maximum Performance is selected for Wireless Adapter Settings in the Power Options window. See What should I do if I cannot connect my VAIO computer to an access point (or the Internet)? for more information.
