A:Answer Hi Noodle,
Thank you for reaching out to us! The Ethernet (LAN) port uses a 10BASE-T/100BASE-TX connector, reaching speeds up to 100 Mbps.
For smooth video streaming:
Change the setting of your wireless router to a high-speed networking standard such as 802.11n if possible.
For details on how to change the setting, refer to the instruction manual of your wireless router, or contact the person who set up the network (network administrator).
If the above procedure does not deliver any improvement, change the setting of your wireless router to 5GHz, which may help improve the video streaming quality.
The 5GHz band may not be supported depending on your region/country. If the 5GHz band is not supported, the TV can only connect to a wireless router using the 2.4GHz band.
If you need further assistance, we encourage you to make use of our many online resources to help with questions regarding your Sony TV.
