To enjoy watching Internet streaming videos, a network with a fast and stable line speed is necessary. In general, speeds that resemble the following are necessary.
- Streaming standard definition (SD) Internet video : 2.5Mbps
- Streaming high definition (HD) Internet video : 10Mbps
- Streaming Ultra HD (4K) Internet video: 25 Mbps
If the speed is slow:
Here are some examples on how to raise and stabilize the line speed of your network. The speed cannot exceed the limits of your Internet service provider (ISP) contract or the capabilities of your router.
Note: Some ISPs apply a bandwidth or data cap to their plans, which limits data transfer and may lead to a display of black screen when using the Netflix service. The Netflix service should still play on a lower speed albeit with poor image quality, unless there are other devices connected to the same network at the same time.
- Make sure the Sony product streaming the video has the latest system software installed.
Installing updated software (if available) may improve the stability of the Internet connection. For TVs, refer to: How to perform a software update.
- If there are multiple devices connected to the network, try using only one at a time.
Other computers or devices on the same network can impact the connection speed and streaming video quality. This is most likely to happen when someone else on your network is downloading files, playing online video games or watching streaming videos online from another device. Try stopping the use of other devices before viewing.
- If you are using an unsecured wireless network, you may be unknowingly sharing your connection with other people in your area, increasing the demand on your network bandwidth. Using a secure network is recommended.
- If using a VoIP (Voice over Internet Protocol) service to send and receive phone calls, the Internet connection may drop when someone in the home is using the phone.
- If you are using a wireless network, consider the usage environment and setup.
- Performing a power reset of the router
- Try unplugging the power cord of the router from the electrical outlet for 30 seconds.
- Plug the power cord back into the outlet and wait until the flashing lights indicate that the router has completely restarted.
- Confirming whether there is any improvement when the wireless LAN router is moved closer. 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.
- 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 connection is suggested instead.
- Optimizing the settings of your wireless LAN router.
- When a nearby wireless network is using the same channel as you, interference may cause communications to destabilize. Try changing the settings on your router to a different channel number.
- Depending on your wireless LAN specifications, the communication speeds, stability, transmission range, etc. will vary.
If supported by your router, connect via [n].
- [n] : Recommended by Sony. Supports HD image quality playback.
- [g] : Not as fast as [n], but stable.
- [b] : Not recommended for streaming videos.
- Additionally, some routers equally divide the bandwidth between each device on the network. Other routers have Quality of Service (QoS) settings that can be adjusted to help manage data priorities within your network. You may need to check with the manufacturer of your router or your ISP to check for and adjust QoS settings.
- Performing a power reset of the router
- In the network settings for your Sony product, try changing the Primary DNS settings.
Your ISP may be experiencing heavy Internet traffic. In this case, performance might be improved by manually changing the Primary DNS Server option to 126.96.36.199 or 188.8.131.52 in the Network Settings menu of the Sony product. If the slow performance persists, try accessing the content at a later time or call your ISP to further troubleshoot the problem.
If there is still no improvement, the usage environment may be preventing a rise in speed. If the network service you are using allows you to change the image quality, view at a lower image quality or resolution. Another solution is available on how to lower the resolution on the Netflix service
If the speed is acceptable:
- Check whether or not your Sony product has the latest software.
Make sure the Sony product streaming the video has the latest system software installed. Installing updated software (if available) may improve the stability of the Internet connection.
- Contact your ISP.
If only a particular network service cannot be easily viewed, there may be a problem with the server that is transmitting the videos. For information on maintenance and other difficulties that the network service may be experiencing, contact or check with the ISP.
