Smart TV Buffers While Streaming

I am using the CGN3ACSMR router to run a Samsung smart TV. I'm finding constant buffering and sometimes 'hanging' when streaming Netflix, Youtube, Prime. I disconnect and reconnect the router and buffering stops every time so this is clearly a router issue. What is the solution?

Thank you.

It's not exactly clearly the router as it could still be the TV. I myself do not trust the router/modem combination. If you have a good router lying around, I would try putting the modem into Bridge mode and use the separate router and see if your issue persists.

For any streaming service to work well, your Internet service needs to work well and your in-home network needs to work well.  The network needs to deliver data from the streaming service to the receiving device at a high-enough bitrate.

 

If you are getting significant packet loss with your Internet service, this could certainly impact streaming.

 

With Wi-Fi, you could be getting a strong signal but if there is interference, you may not be getting a high-enough bitrate on the Wi-Fi connection to sustain streaming and your audio and video either drop out or streaming stops until enough data gets buffered to resume streaming.  Another problem is that you could either have too many people in your area sharing the same Wi-Fi channel and/or you may have too many active WiFi-connected devices with poor Wi-Fi connections.  All of these devices share the same airspace and you cannot have multiple devices transmitting at the same time.  If a device has a poor connection, it will take more time for it to transmit or receive data, and this consumes more "air time", and degrades Wi-Fi performance for ALL devices sharing the same channel.  If you and a nearby neighbour share the same Wi-Fi channels/frequencies and your neighbour's Wi-Fi network performs poorly, then yours will as well.  (Fellow network nerds: please forgive me for over-simplifying these concepts.)

 

It's also a possibility that the problem is due defective hardware.  It could be the Rogers modem, your Wi-Fi router, or even the Wi-Fi/network hardware in your TV.

 

A few Ignite TV customers have also reported audio/video dropouts and other similar problems -- and it's not a problem with the Ignite TV service itself; it's almost certainly caused by a network connectivity problem... somewhere... and the only fix is to identify and resolve the underlying network problem(s).
