Android TV 1 (very) poor Network performance

[nicogri]

Hi guys,

just a new thread to tell you guys how I am disappointed (sort of) with my new Android TV from Sony KD65XD9305.


I just bought this TV with a pretty great discount (2000€) and picture quality is very good.


For Android TV, I find it stable and fine. The main reason I chose Sony was for Android TV (I didn't wanted WebOS or Tizen).


So as I use the TV ONLY with network stored media, I plugged the Ethernet cable to get something reliable and fast...


HORROR !!! Ethernet port is not Gigabit... Sony are you kidding me ??? How do you plan to stream 4K HDR content to the TV with 100 Mb link ???


Let's do some math : Movie 2h00 / 63 GB = 64512MB to send to TV in 2 Hr so / 7200 = 9 Mb /s we are pretty close of the max we can output on 100mb network so as the bitrate is variable and some actions scene require much more of it you get bad picture lag and audio drop in half of the movie.

To confirm that it was not decoding problem, I putted the file on an external HDD plugged directly into the TV and had no problem at all.

So I wrote you a mail Sony, to explain that to you... 1 week later I got a person with no knowledge whatever who told me that I needed to run a speedtest because it was my internet (WAN) connection that was slow.

Just LOL ^^

I told myself that I was doomed.

So I search again and discovered that the Onboard wifi was 5 Ghz AC compatible. Maybe a way out.

So I droped my Cisco Meraki 300N Wifi and I got a TPLink Archer C7 C1750 (so it meens 900 Mb theorical on AC 5 Ghz)

It could have solved my bandwith problem on local network !!!

And guess what... it didn't because I think wifi chip or driver or ??? is total crap...

The TV is at less than 1 meter of the access point (no wall...), connected at 5 Ghz and I can't get download bandwith to a minimum of 100 Mb (a joke).

If I do the same test from the same spot with the same app at the same time on the same wifi of the same network with my phone (Google Nexus 6P) I get approx 230 mb of bandwith.

Screen cap are just at the bottom

What do you want to answer to that ???

So your Smart TV of 2016 is just to slow to play a 4k movie of 2016 (I tried Mad Max and Deadpool) on local network (no matter how good network connection is, I have full gigabit network at home).

So now my very precise question : Do you plan to adress this problem Seriously upgrading Wifi driver / firmware to get real fast connexion (as I am sure you cannot upgrade wired card to gigabit with software upgrade) ?

I am available if you need more statistics and / or informations with the test environment.

Hi there

Sony do not generally post on this forum, hence the reason why its called a "Community Forum".  Having said that, the users who have the ranking of "Expert" do have direct contact with Sony.  If you have a Case ID number, I will re-escalate this back to Sony.

Your TV is still on the Lollipop version of Android (version 5.1).  I am hoping that the new Android version - Marshmallow (Android 6.0) may improve things (ETA unknown) in regards to poor wifi signal and performance. 

Cheers

Yes, 802.11ac WiFi performance unfortunately is also pretty poor. Here is my review on the matter.

I have the same problem with my KD55XD7005.  I bought a 4k Android TV mainly so that I could play 4k content over my network.  I am hugely disappointed about this - in this regard it is basically not fit for purpose.

Btw, my TV is running 6.0.1, so Android 6 is clearly not the answer.

[nicogri]

Man I just read your doc and if I had found it before buying the TV maybe I had bought a Samsung ^^

So Wifi "cheap" (ok chip) is connected on USB2... it's not sexy but it shouldn't be a problem.

In real life USB2 can substain 30Mb stable datarate (when you transfer data from / to external HDD for examble).

So with 18 Mb bitrate movie we have some 10 Mb margin.

For network purpose it leeds us to 30*8 = 240 Mb bandwith so it should be good (as the screen cap of my phone)

Problem is that we are very very far from AC rate or USB2 rate on this chip.

As we can see on the picture of my TV, the bandwith is better when we perform an upload test. It is strange because a TV is by essence a device design to receive media and display it not the other way.

So as it has been stated that Marshmallow (6) is not a solution to this problem, how can we do to have Sony looking into it ?

I don't ask much, I just want wifi to operate normally with normal data rates.

PS : My case to sony support was 15153108

PS2 : I also tried to plug a USB3 Gigabit Ethernet adapter (TPLink) on the side USB3 port of the TV but it was not Android compatible so I get nothing (I have it at disposal so worth the try) I saw some Adapters on Amazon that states to be Android compatible but don't want to invest more money to waist... (can be Android compatible but not Android TV...)

Maybe I do not undestand the problem in the right way..... Probably technology will enhance in the future but streaming more than 100 mbps to a TV is too much in anycase considering that most of the services are via internet. Actualy Netflix use 15mbps to stream 4k/HDR contents, I've read that UMAX in Korea can stream 4k 60fps at 32mbps so the real future is the compression alghoritm not to use a very huge bandwith.

So coming back to the problem, what kind of encoding/compression have the files you cannot stream on your TV via cable? Or if you don't want to use any compression in order to have the best possible quality, probably streaming is not the road (UHD BD player?)... just my personal impression

[nicogri]

I don't have a correct answer to that because... it depends !!!

For my personnal case, I cannot stream anything at all from internet (live TV, netflix, youtube) even on full HD and slowly on 720p.

My house is in France in "the countryland" so my DSL relay is at 4.8 kms and I get an incredible 2Mb downstream (that make 300 kb/s)

So now for the local network bandwith matter (Gigabit power).

We have to make a difference beetween Bits and bytes (in Frenches it's Mo or Mb).

A movie like the Korean one with 32 Mo /s can require 32*8 = 256 Mb network to stream...

For the bitrate itself it's a thing that cannot be overlooked.

Anything can be 4k if it match the 4k resolution but it won't make the most of the picture.

The quality will come more from the bitrate the file was encoded than the resolution.

For the files I tried they were heavely encoded with new h265 codec but 10bits HDR have a price in Giga 😉

So Yes I ask a lot to this TV but it's a high end Sony prodcut so I hoped it can provide (and it can decode it on USB harddrive so why not on LAN)

Here are the details of the 2 movies I tried :

I do not have the right answer too, the problem is quite complex

In any case I'm always speking about Mega bit per seconds (and the Korea example is 32 Mbps not 256).

If I understand correctly your file infos it should be 60 mbps video plus 10mbps of audio tracks, so not heavily encoded but still beyond the physical limit of the network card of 100 mbps.

the bottleneck could be (just could...) anyware in your network setup (router, cables, interference, the TV itself). I'm always referring to wired LAN, because wifi (even on 5ghz) is highly not reliable for such kind of streaming and the bandwidth declared is just theorical.

I did not try to stream any 4K content to my TV via LAN, but i had some problem even streaming FHD 60fps with 32mbps bitrate coming from my own camera recording. I've solved, whenever occurred, via the following resolution:

• streaming via wired network(not having the possibility to pass the LAN cable, I'm using a TPLINK 500mbps powerlink)
• sometimes the powerlink needs to be reset, in order for the video not to stutter
• use only the Video stock app, other player cannot reach the same performance (Kodi, Archos, VLC)
• sometimes the TV itself needs to be rebooted (via pressing the remote poweroff button for 5 seconds)

I doesn' like Wifi either (as for CPL)

As an IT professional I only rely on wired connexion and I would have for the TV if it has been Gigabit (I still can if Sony points me to a working USB3 adapter).

As for my home network, I confirm that it has no bottleneck (confirmed by the speedtest on my phone on Wifi @ 240 bps)

Files are  stored on my computer on a 2Tb sata drive, Ethernet chip is Intel Gigabit plugged into a 8 ports Gigabit Netgear Switch, This Switch is plugged to the "core" switch of my house a 16 ports Netgear Gigabit itself plugged into a last 5 ports Gigabit Netgear Switch in the drawer under my TV where I have my New Archer C7 (gigabit LAN AC1750).

All switches are managable and managed and are all operating at Gigabit Speed when available (so on all uplinks at least). I dont use my router as switch to separate roles and prevent performance issues.

For Kodi or VLC, I think at first that they could have been guilty that's why I took the pain of installing a dedicated app to test performance and compare to my phone.

This give real numeric statistics and 50 mb download on a AC Wifi is not good.

Here is the app I used. There is a server component that runs on my computer in a command shell (no installer it's standalone) and "publish" a generic tcp server on the network.

The client android side connect to this server to simulate upload and downlods of files with various options.

As this app is not compatible with android TV, I installed it manually with ES Explorer after allowing anonymous sources.

That's also why I really want Sony to look into it. I don't find logical that we (the customers) need to do there work of diagnostics. This TV shouldn't have leave engineering office lacking descent network performance. What would have be the price tag to upgrade from 100 to 1000 wired card ? 5$ per unit ?

HI guys

I know that you have spent quite a bit of money on the TV and additional equipment - but I also consume most of my content via HDDs on my network.  However a long time ago, I gave up streaming high bitrate files over my network (also gigabit), but I invested in a dedicated Media player that attaches to my TV via HDMI.  I can stream files to it if needed (also gigabit) even via a NAS drive but for me I chose HDDs attached to it (due to the cost factor which was spread out over time).

I chose a company called Mede8er and the media player model is MED1000X3D - yes it a few years older now and does not do 4K (which I understand a new product will be released next year!) - however there are other various media players out there.

Potential solution?
