Buffering/Latency issues

Buffering/Latency issues

Hi Xfinity,
We have been having some issues with buffering when streaming videos and watching youtube. I have ran some ping tests and have the results. The latency is a bit high and we are having packet loss so something is wrong. Can you help?


I have this modem: http://www.arris.com/surfboard/products/cable-modems/sb6183/


and this Router: https://www.netgear.com/home/products/networking/wifi-routers/R7000.aspx

 

Here are some ping tests over the last 2 days:

Re: Buffering/Latency issues

Is this with a WiFi connection ? If so, for a test, does a computer hardwired directly to the router with an ethernet cable have the same problem ?

Re: Buffering/Latency issues

Hi EG,

Yes this is over a Wifi connection. I will also test with hardwired to the Router and post the results..

I dont see packet loss although the latency is still higher than 30.. What does this mean?

 

Here are the results hardwired to the router:

Re: Buffering/Latency issues

Again, I tested the packet loss and latency with a wifi connection (Not hardwired to the Router) and I am back to having packet loss issues and pings above 30. When I do a speed test at Speedtest.net I get good upload/download readings but the ping is always between 50-75ms. Thing is my laptop is not the only one suffering these issues. It is every computer/laptop in the house. What could be causing this?

 

Here are the results with the Wifi Connection again..
