Netflix eating 100% out of bandwidth ( ~100Mbps )

[ville_K]

Here's the problem.
Smart tv with netflix eats around 100 Mpbs out of my bandwidth thus making it unuseable for anything else.

Netflix shouldn't be eating even over 50 Mbps when streaming a 4K video, so where might the problem be at?

Speedtest with Tv off, steady 98-99 Mbps connection
with it on 700-900 Kbps

My Modem, EPCxxxx something (100Mbps cable connection) doesn't have a QOS setting because of our ISP's custom firmware they put on it ...

Who is your ISP? Please provide the full modem make and model if you can. Is it truly a modem and not a modem/router?

Custom firmware: overall not a good thing for end users for a number of reasons. Not relevant per se so will forego that rant...

Although you subscribe to 100 Mbps it is doubtful that you will truly receive that. Read the fine print in the ISP contract or EUA..

And then wireless within your network will slow traffic even more.....

My immediate thought is that you might be able to get your own router and perhaps apply some QoS settings therein.

However, that thought is very premature as the problem still needs to be specifically identified.

If there is some interference or other issue with the wireless connectivity to the TV then packets will be sent and resent due to errors. Can slow things up considerably.

Did it ever work correctly? Can you temporarily move the TV around to see if signal strenth/performance improves or degrades even more?

Verify the SmartTV's wireless configuration - may not be set up correctly to match the modem (or modem/router).

ISP = DNA oyj ~corporation in english
modem model = sagemcom FAST3284 DC

The average down / up speeds are about 98Mbps down, 11Mbps up, so that's not a issue.

And those speeds are with Wifi through a router which works as a wireless bridge ( Asus RT- N56U with tomato firmw. )
This router is fully customizable and as far as i know can have a dozen different custom firmwares installed onto it.

The range on the sagemcoms crap is so small i bought that asus to make the wifi range & work better, which it did.
( Steady near 100 Mbps download, low latency etc. , on wifi )

The tv is set to connect onto the sagemcom (There's not much of a setting page, only configurable things are the TV's IP & DNS), and with my smartphone i got around 40-50 Mbps download speeds on the same spot.

The only problem seems to be that the sagemcom modem/router, sends all the bandwidth over to the smart tv, even though it doesn't use all of it / need all of it.

Easy fix would of course be, if that sagemcom modem had some QOS settings open, which it doesn't

QoS is only going to be viable if the bandwidth is available to begin with....

All other things being equal, I would expect that the TV's wireless performance would be the same as the Smartphone (40-50 Mbps) in the same spot.

However, with the TV's performance/presence being so much lower (700-900 Kbps) then, in my mind that probably indicates a problem with the TV's wireless transmission capabilities and or configuration. When the TV is on does the Smartphone still get 40-50 Mbps?

Does the following link show your modem:

Network:

IPS (DNA oyj)----> Sagemcom modem/router <~~~~~wireless~~~~~~>Asus Router(w/ Tomato) <~~~~~~~~ wireless~~~~> Smart TV

Sagemcom being the DHCP Server and DNS Gateway.

What I am working towards is some definitive (hopefully) determination of the problem being hardware or configuration.
