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.

No, the Netgear does not work on the TV.

I just wanted to say that the Netgear has a similar chipset to the one in the TV (MediaTek), but the throughput it achieves on the PC is much higher than what the TV can do.

I have a feeling the WiFi throughput is reduced drastically with distance and obstacles in between. My access point is 3m from the TV accross the room and I achieve 100mbps. But at those signal conditions it should at least reach full USB 2.0 speeds (>200mbps).

Hi ,

The distance between my telly and the router is about 50cm. 

Connected with cat5 Ethernet cable and still below 70mbits. 

Samba disabled as you previously mentioned. But still lagging and buffering thru smb 😕

any idea? 

Ps: How the hack you can get guys 100 and 120 mbits on smb with 5ghz wifi???

I have seen WiFi appliances where a too short distance <1m caused even more trouble than long distances...

Hi, thanks for the discussion,

I was able to up speed for my SONY BRAVIA KD55XE9005 55 from 70mbps LAN to more than 100mbps, now movie with 70mbps bitrate an more I can watch with out problems.

I used Kodi with Serviio.

P.S. kodi with SMB max was 70mbps.

P.S. WIFI was also slow, I didn't test yet it with new apps.

You won't get "more than 100mbps" out of a 100BaseTX port .

I was able to achieve +200 mbps download and 150+ mbps upload through 5 GHz wlan using a tp-link archer c3200 router (right under the tv). However, I still cannot play 4k perfectly in my xbr75x900e.

it plays just fine when the external drive is directly connected to the tv's usb3 but my goal was to use the drive connected to the usb3 port in the router.

Windows 10 get average 30 mb/s read/write and play all video files just fine but it seems like the tv won't get there for some reason, not sure what's the bottleneck here...

kodi can play a little better than the native app, i was able to watch the lastest bourne film (4k, 60 gb, 2h length) with apparently no issues but 4k@60Hz videos won't play properly (and a 20 mb/s read should be enough for that)

ps: sorry, my english sucks

[l0ppi.]

I'm having the same issues and I'm quite sure it got even worse after the latest, small FW update.

I can't play anything with more than about 40 MBit/s properly. I've already tried it via ethernet with different cables and via WiFi with different setups (router right in the same room as the tv, repeater connected via cable to the tv and via WiFi and so on).

It's extremely annoying and makes the tv almost useless now. Even Amazon streams in 4K stutter occasionally.

My network has no bottlenecks (everything is GBit ehternet hardware, the NAS for instance can put through about 120 MB/s and the internet connection is rockstable at 50 Mbit/s).

So there's absolutely no reason for the tv to perform that terrible. Even the (absolutely ridiculous) 100Base-TX ethernet adapter should not be the problem.

Has anyone achieved a stable connection for videos with about 60-80 MBit/s?

With an older firmware and The SAMBA service turned off it plays any 4K file I throw at it over Ethernet.

Doesn't matter how much transfer you get in a solo network transfer test. When you want to play a big file (basically HEVC ones) and the chipset has to process together the transfer and playing, it just get bottlenecked and performs like a miserable 35€ raspberry Pi .

[Kuschelmonschter]

A cheap Pi has even more processing power than current flagship TVs by Sony.
