Issue with gigabit switch

rickmomenton · 5 Jan 2018 at 19:15

I purchased a Netgear Gigabit switch because I was getting buffering on some large video files when streaming to my LG TV which is downstairs.

I am using cat 6 ethernet cables and 1 cable connected from my gigabit switch to my router (BT Home hub 5) and the rest connected to the switch, however I see no improvement in speed I still get buffering the same as before and also when uploading files from pc to nas I max out at only 62mbps.

I'm using 600mbps rated homeplugs and my nas is synology ds216j with wd red 3tb.
In synology network settings it says 1000mbps full duplex.

Anyone got any ideas?

62MB/s is 492Mbps, so for 600Mbps homeplugs, you are pretty much running them at as fast as they will go, taking housing wiring into consideration.

62 megabits not megabytes sorry for not being clear, in the synology resource monitor it averages around 7-7.8 MB/S so maxes out at around 62megabits.

Do this as a first step in diagnosing the issue.

Just took my nas downstairs connected it directly via cat 6 ethernet cable and I get around 13megabyte (104megabit) max speed when checking synology resource monitor and the videos play much more smoothly just get the occasional buffering for around half a second, do these speeds seem right to you or is something still not right?

Powerline is causing the first limit.

13mb sounds like 100mbit limit from either a switch,port or cable. (100mbit = 12.5mb/s)

Is your TV gigabit?

I'd use a dedicated player instead of the TV for playback.

I think you hit the nail on the head, my TV has a fast ethernet port 10/100 so not gigabit and this explains the speeds, I will invest in a dedicated player.
Many thanks to everyone for the help.
