A:
Any wireless product can experience slow connection speeds. It is normally due to the distance away from the router or other electronic devices in the home interfering with the wireless signal. To improve the wireless connection, try moving the router access point closer to the Sony product that is streaming the video. If the router is close enough, using a wired Ethernet connection is suggested instead.
The following connection speeds are recommended for streaming Internet video:
2.5 Mbps or higher for standard definition (SD) video
10 Mbps or higher for high definition (HD) video
