I have some very odd problem at night. I can only stream 480/720p(sometimes can reach 4k but only can hold like 1-2minute then drop it to 1080/720 then back to 4k,up down up down, unstable) on my sony smart tv at night,no problem at daylight time, can easily get 4k HDR quality in 10 seconds and the speed won’t drop, And I tried watching on YouTube or Amazon Prime Video both app can get 4k quality even at night, back to Netflix app it can only stream 480p/720p. Contact Netflix they said there’s no problem with them and suggest me to contact ISP, but TM said there’s no problem with them too. I tried restart my WiFi router,restart my tv, unplug LAN cable on the tv, uninstall Netflix updates on tv, reinstall Netflix update, nothing work. Anyone facing same problem? Idk what should I do, this problem really drive me crazy.

This is what I got this morning

Too many users at night on the same backhaul

I should contact unifi or Netflix? Tm just ask me to do speed test, if I can get full speed on speed test then they won’t help anymore, they will say there’s no problem with them, suggest me to contact Netflix

Can't do much really. Just need to capture your evidence, like the speedtest results,and log report to both side. The more people log the issue, more likely they will upgrade the service quality

About the Speedtest, I can get 30mbps,this is why I’m asking why only can stream 720p even my internet speed is 30Mbps

Because most speedtest such as SpeedTest.net only reflect domestic traffic speed. It does not reflect international traffic speeds in which many of these services are hosted such as Netflix etc. Since Netflix also has its own speedtest at fast.com, you should try that and compare to your speedtest.net results.

I did, it get 25-30Mbps

Test during the issue. See what's the speed looks like.

Try open netflix on different platform during that time as well. Compare with as much devices as you can.

I not able to check picture resolution if playing on iphone, there’s no option to choose or see what resolution of picture are playing, but it’s pretty clear that I can see, will try on computer later

Try do an nslookup www.netflix.com and tracert www.netflix.com from your computer using command prompt.

Just type nslookup in command prompt?

Yes nslookup then www.netflix.com. After that tracert www.netflix.com.

Ok, will try later, thanks for the reply

You are definitely throttled. I used to have that. May i know if you are using ipv6.

How to know if I’m using ipv6?

You can check from the connection properties of either your LAN or WiFI connection. If IPV6 connectivity reads Internet then you are using IPV6.
Or you can just visit this page https://test-ipv6.com/ on your computer or Smart TV.

I tested on my smart tv, it said
i -Your IPv4 address on the public internet appears to be ........
X -Your ISP appears to be TM suck net
i -No IPv6 address detected
i -You appear to be able to browse the IPv4 only. You will not able to reach IPv6-only sites
i -To ensure the best internet performance and connectivity,ask your ISP about native IPv6
i -Https support in now on this site
“Tick” -Your DNS sever (possibly run by your ISP)appears to have IPv6 internet access

Should I setup IPv6?

This post has been edited by RonanGow: Jan 18 2018, 11:11 AM

You could try but I doubt it would make any difference. Have you tried other DNS like Google DNS or OpenDNS?

I’ve set google dns on my WiFi router

Dont use ipv6. It will not improve. But it might make it worse. Ipv6 was great a year ago. But now tm "spoil" it by throttling it at certain times. What u can do is try to restart yr modem/router untill u get less "throttled" ip range. The best i could get are (60.x.x.x) or (124.x.x.x) or (1.x.x.x)
Sometimes 115.x.x.x is okay but not recommended. 175.x.x.x is the one to avoid. Very harshly throttled at certain times. Keep in mind this is not a godsend or miracle work, but it could minimize yr throttling problem. I have been keeping my 60.x.x.x for months now and i stream 4k hdr everyday with no hicup. Although i will have some 4k youtube buffering and kicked down to 1440p around afternoon till mid evening. Not a big problem to me cz mostly my tv is on at night. Its sad, but gotta live with it. Wonder if maxis fibre have the same problem.

Nowadays fast.com is following the footsteps of speedtest. No longer true speed from their servers.

Maybe they started losing some potential new subscribers when show the actual speed, which is slower, so eventually they follow speedtest method.

I tried to restart my WiFi router several times but doesn’t work, IP address will change after WiFi router restart? No issue watching amazon prime/YouTube 4k at night, only Netflix got problem,some times can get 4k but it only can last 1 minutes then drop to 720p.Will try the methods that you suggest. Thanks for the respond

No wonder my speed reached 42Mbps sometimes on fast.com but my internet plan only 30Mbps, haha

Yes it will change. But sometimes it will take a lotttt of restarts to get good ip range. May i know whats your ip range? Dont need to send all of them. Just wanna know the front number. Mine is at 60.xx.xx.xx for example.

My IP address is 192.xxx.x.xxx
Isn’t this is WiFi router address?

Your IP address can’t be 192.xxx.xxx.xxx, it is your internal LAN IP. Go to whatsmyipaddress.com, and that would be your WAN IP.

Oh, it’s 60.xxxxxx

Huh? I tot this only happens during streamyx era? For unifi, all IP ranges are the same. The only thing you can do is to Disable IPV6, flush your dns and lastly reset winsock if all of them aren't working.

I'm currently on 175.138.218.xxx IP range, nothing wrong with my speedtest. Done all the tests with fast.com, speedtest.net, testmy.net, dslreports.com. All are running fine. Below is an image from testmy.net
I am using UniFi Lite,the speed is quite good. Netflix no buffer at all.

I didn’t set up for IPv6
This is Test on my computer by speedtest


This test on TM speedtest Page


This is Test on fast.com on my computer


This test on my iPhone by fast.com app


This is Test on my tv


This is what I got in Netflix app on my tv

Let me test on my TV and see how it performs. Will update at here.

You should test at night haha

Sure, I will test it later at night.

Okay, after I tested out, I found out that my speed in netflix was 3/4 of my speed from fast.com. Could it be anything that slows down the speed on your TV? Is your TV connected via wifi network?

This post has been edited by mztang52: Jan 22 2018, 09:41 PM

Nope, my tv connected via LAN cable. I can easily get 4k at now theses days, maybe TM has reset their “device” at my area, thanks for the help dude!

You're welcome though.

This post has been edited by mztang52: Jan 23 2018, 10:36 PM

My netflix test is 46mbps but only can watch at 720 reso

Could it be hardware limitation?

I can get 4k during daytime and sometimes at night

Server congestion issue?

Netflix server? Maybe

I'm using sony smart tv too with netflix apps inside. last time even with streamyx 4mbps can easily get 720p. 1080p can get it but it will take a while, maybe close to 1 minute

you are not alone with this. i wasnt throttled for a while until a month ago. i will be throttled at around 830pm-1am. its gonna be throttled like crazy. imagine 480p-720p max on a 100mbps unifi. i am still having the same problem with it. youtube 4k is not affected which confirms that the line is not congested. my way around it is to connect to a community vpn server (eg:vpngate) and it will stream flawlessly getting 15mbps 2160p. but as soon as i disconnect the vpn, it goes to pixel town again. LMAO. tried calling tm but they dont see it as a problem because speedtest.net shows perfect 100mbps down and 50mbps up. just fyi, all my device wired lg tv and laptop are throttled. wireless side on my iphone and android phone is even worse. dont even know what else to do anymore. im sorry for anyone who face this, i understand how it feel.

Please take note that Netflix is not hosted in Malaysia therefore it relies on the international gateway which most of the time is beyond our control(Also depends on TM's routing policy). Local Speedtest only measures domestic traffic which again doesn't really say much about the overall internet experience as some services aren't hosted in Malaysia.

Im afraid im gonna break yr bubble pal. It is hosted in malaysia. In fact its hosted at telekom malaysia cdn itself. Take a look at my screenshot i took a couple of days ago.


Attached thumbnail(s)

i can stream 1080(5000bitrate) just fine with 8mb speed, just have to wait for less than a minute. Sometimes when isp is throttling then just restart my modem/

Yeah but not all though. Most of the stuff I watch are coming from SIN00x, Singapore, I assume. These take a while to ramp up to 1080p. The locally hosted ones are much faster, of course. Matrix for example is hosted here. Pacific Rim is from Singapore, if you like to test.

True. Although we have local CDN, not everything is hosted there. Even most of my services don't use local servers.

I just saw the sin00x u just mentioned. Thanx for pointing it out to me. Its funny that it changes though. At the mentioned throttled timeline(8pm-1am) for example 'that 70s show', it will be on sin00x an stream at 2-3mbps. Outside the throttled timeline it will be streamed on telekom cdn. So i know the same show will be on both cin00x and telekom cdn. I included both screenshots taken at different time. U can clearly see (sin00x = 3mbps) and (telekom=101mbps).
I also included a screenshot for the pacific rim just for support. Im trying to be as clear as i can.


Attached thumbnail(s)

You're right. I just checked a minute ago at 11:30am. Everything I tried is streaming from Telekom servers. I tried Matrix, Pacific Rim, Avengers Civil War, Benji, Ace Ventura, Ricky Gervais Humanity, Russell Peter Notorious and an episode of Dexter.

I'll check again tonight and see what happens. I wonder what's their criteria for falling back to Singapore's servers. Maybe when Telekom's server reaches a certain load? If I look at the CDNs for Benji, I see one SZB, 2 x SIN, 4 SYD, Sydney? So perhaps they fallback from one to another depending on load.

So to RonanGow, I would say this would be Netflix's problem.

For the curious, shift-ctrl-alt S, D and L.

Most probably too many people streaming Netflix. But I believe you can change the CDN that Netflix uses as shown below as well as set the bitrate so that the video quality doesn't degrade.



This post has been edited by faizyunus: Mar 26 2018, 01:55 PM

Yes, can. If I’m on SZB, both SIN and SYD appears as options. But if I’m already on SIN, SZB isn’t listed as an option.

Have you tried accessing Netflix using TM's DNS servers?

No, currently using Google and OpenDNS. Will give it a try. Does it make a difference?

This post has been edited by soonwai: Mar 26 2018, 02:24 PM

i often get MY server and streams at full speed when using chrome , but whenever i use edge or win10 netflix app i will most likely only see a lot of singapore servers without MY server and those SG servers only allow me to stream at 20% of my internet speed.

i second this question. will it make a difference? i might just point my netflix devices to their default 1.9.1.9. please confirm this if u have variables. thanx

tried using default settings so i am obtaining dns from tm which are 202.188.18.188 and 1.9.1.9.
as per today, my cdn changes to spore and remain that what despite being changed to default tm dns. another miserable evening on unifi. maxis fiber users come in please give some feedback. i heard maxis is now doing better at netflix/youtube 4k. thanx

The response for Netflix servers maybe different. Another way would be to VPN to Malaysia server.

This post has been edited by faizyunus: Mar 28 2018, 07:15 AM

Very nice. How is it different?

Do you mean VPN to Malaysia VPN server even though I’m already in Malaysia?

Try changing the Netflix playback setting to high. This might solve the problem.

Guys/Girls,

I too have been suffering from this bullshit for the past few weeks. This does look like Netflix is being throttled at certain time of day. Around 8-12pm everynight I will get no more than 1080p, sometimes down to 720/480p. My router indicates that the TV is CONSTANTLY using 5Mbps download speed- It looks like its being hard capped at that speed.

I have spoken to Netflix support - not much help from them but they did some live testing while I was on the phone and they said my bandwidth is limited.

Some relevant info on my setup:
- Netflix on 2017 LG smartTV (everything up to date). There has been no firmware or Netflix app update for the TV for at least 2 month. I only noticed this issue for the past 2-3 weeks that means this is not a software issue as it was working fine with the same software for months before this.
- 50Mbps unifi
- TV connected via gigabit ethernet to the router.
- Speedtest on any app or device in the house (including ones connected via WIFI) and the Netflix speedtest on the TV itself will constantly show 45Mbps++.
- ASUS 5300 router.
- AMAZON TV, Youtube runs 4K without a hitch.

Can anybody point me to the right channel to report this - I am done talking with their hotline staff. This is beyond their pay grade.

This post has been edited by zainframe: Apr 3 2018, 09:40 PM

Unfortunately no . This was the first thing Netflix tech support told me to do.

Can confirm that nights the video quality drops as you had reported.

This post has been edited by XPS: Apr 19 2018, 08:59 PM

I noticed Unifi Mobile also have this dependency.
Probably running on same backbone.

try to get a vpn and test it out, sometime our ISP is detect certain traffic pattern and slow down the speed during certain period.

One main different for me is that when i stream video on facebook, it buffer a lot sometime. After turn on vpn, the speed go back to normal.

I believe they turn on qos on certain traffic pattern or depends on certain destination IP that often slow down the network. If based on destination IP, the only way to get around it is vpn.

not 100% confirm is due to this issue but certainly worth to try out.

Some DNS Servers may have different IP range responses for sites. Simple example would be Google.com, if you use TM DNS and Google DNS the IP response you get will be different.
Yup. It may help with the routing issue.

This post has been edited by faizyunus: Apr 6 2018, 09:45 AM

Omg! Same bloody issue with me... I’m on unifi 50mbps... every night around 8.30-11pm Netflix is total nonsense...

I dont think tm throttle only to netflix. Most likely the link to netflix cdn is congest. For CDN, its not provider server, its own by service/application owner. Since the behaviour only at night.. logical thinking.. night everybody watching netflix.. so the CDN able to give all user fair usage policy kind of balancing traffic..

If rhe provider has CDN with any content provider, it will be their own effort to do the cdn and caching to make users have good experience.. no provider able to make sure user get their "best effort internet service" to where user want to go.

Suggested bandwith for 1080p video for netflix is 25M... if you subscribed 30M internet, sometime you can get full hd & sometime not if the internet also shared by other devices....

Only around 5Mbps is needed for 1080p. 4K UHD can be streamed using as low as 15Mbps (the bitrates will be low but it will stream in 4k at this speed). These speed requirements are not theoretical - I have tested them myself. I have a 100Mbps line which is not shared with any other device/service (at least while doing all the testing). The TV is connected directly via gigabit ethernet to the router.

It could be possible that Netflix's CDNs which I am connected to have maxed out their bandwidth (as suggeted by ntah_le) in which case someone has to answer about this (that would be Netflix since I paid for the 4k UHD package). However, I have spoken to Netflix and they claim that there is nothing wrong with their 'transmission'- a live test with them (they tested while I was on the phone with them) indicated that they can only stream 5Mbps to my device. This could be a tai-chi 'blame it on the ISP' statement from them, I dunno.

These past few weeks if I am lucky, between 8-10pm at night I am getting max 5Mbps/1080p streaming speed for Netflix (sometimes only 1Mbps/480p). If this is a TM issue it means I am only getting 5% of the total bandwidth I paid for every single night which does not make UNIFI a 'best effort' service.

This post has been edited by zainframe: Apr 14 2018, 07:30 PM

Is there anyway on iPad or iphone netflix app to display stats like what you have in a browser?

As far as I know no. I even tried the key combos with Bluetooth keyboard connected, it doesn't work.

The problem is Netflix and they should escalate the country specific issues. Both the TV Neflix app speed test and many reliable speed tests confirm that getting a fraction, a small percentage of the speed tests, cannot be purely caused by Unifi traffic shaping (and you can tell whenever TM does shaping or have international link issues if you know what to look for and test). Been looking at this for a couple of weeks before posting here and its clearly Netflix as gaming traffic, buffer bloats (QOS for media) and everything that reasonably makes sense points to Netflix being the culprit.

For now, just report to Netflix and hopefully if they see enough reports, take some action. Its very obvious when YouTube is not affected.

I've spoken to Netflix a number of times - they claimed nothing is wrong on their side but as I said before this could be a taichi move from them. Also this past week I have started having problems with Amazon TV - more or less the same issue where my streaming fluctuates between SD/HD/UHD every few minutes. Any speedtests I tried including Netflix shows that I'm getting at least 85% of the 100Mbps at all times.

Really frustrating when all the service providers taichi-ing and denying. Unifi, Netflix and Amazon are not free services .

Its probably Netflix having bottlenecks at their end. On router side, application bandwidth monitoring, the traffic is not constant just like with YouTube. The peaks are a lot more than 5Mbps and if Unifi is the issue then the peaks will be that 5Mbps cap figure Netflix is claiming. Traffic shaping tends, as past experiences show, limit the speeds considerably.

For now its easy to blame Unifi however facts seem to point towards Netflix. Only recently had Netflix showed the poor bandwidth.

More investigations, seems that most of the Netflix servers are from SG with IPV6 server prefix. So far counting close to 18 servers. If you can turn on IPV6 it may help

This post has been edited by XPS: Apr 21 2018, 07:53 PM

Update. Seems Netflix servers with IPV6 prefix does improve the connection quality. Seen a lot of SG and some SYD servers with very little on MY side.

I dont think my TV supports IPV6 - if so anyway I can use IPV6 to access these servers via my TV? It's the only Netflix device that supports both Dolby Vision and Atmos.

I had a 1hr+ chat with Netflix a few days ago via their IM - I think the support guy slipped and implied that they suspect that the bandwidth to their CDN servers are overloaded. If so then they should pay for more bandwidth before selling us the service. I saved the transcript.

Anyway in the end I was AGAIN given the run around without any straight answer (the standard 'you should check with your ISP' answer).

It seems that when raising this matter to both TM or Netflix they would just blame the other party without really investigating the issue . I told them that they should provide some evidence that the issue is not caused by their service before blaming the other party. But I am only a customer to them what do they care?

This sucks.

You need to check if IPV6 is enabled on both the router and the TV and there is some connection algorithm on Netflix side that prefers IPV6 at least from tests past couple days. Using the TV mostly for Netflix and the "info" button is where the quality and bandwidth used is indicated. Seen probably 20 servers now (using the router packet inspection) and 90% are SG or SYD. Of the offshore servers almost all are indicating IPV6, therefore if others can confirm they are getting better results, we may be onto something.

Hey guys, im back. As u know i battled this for the past a few months. I can comfirm cdn on sin00x which is the sg based cdn is NOT slow by any means even at peak hours(both ipv4 and ipv6), specifically 7pm-12am. Thats because both maxis fibre and time fibre are using sin00x at peak hours. The only difference is, both maxis and time never has speed issue towards six00x. I can vow for it since i just terminated my unifi 100mbps and replace it to 30mbps maxis fibre.

It is so funny that my 30mbps is sooo much better in term of netflix/video streaming. 4k hdr netflix is 100% streaming at 29mbit/sec 24/7.

Whoever wants to do an experiment of their own. I have a openvpn server running through my pfsense router which is connected to my maxis fibre 30mbps. Feel free to connect to it at peak hours. Pm me to connect to it for netflix purpose.

Cheers.

You just evidenced TM doing traffic shaping, which is not surprising since TM has a lot of experiences, equipment and software going back to early Streamyx.

Unfornately, for low latency connections eg gaming, TM is still the most reliable compared to Time or Maxis.

So we now know that TM lets you speedtest at 100Mbps and then traffic shape to a low speed flr say Netflix. This may support the earlier suspicion that Netflix IPv6 connections seemed faster, probably as more people are on IPv4 connection.

Guys,

I have brought this matter up with MCMC and TM has actually replied with an official letter to me saying that they do not practice 'bandwidth throttling' and the Netflix issue is not due to any intentional action done by them. It is a 2 page letter with the normal Fair Usage Policy, them not accountable for websites being slow, network congestion and other standard stuffs but they did OFFICIALLY replied to me stating that this is not their (intentional) fault nonetheless.

Any advice on how I should move on with this matter? Should I shove the letter to Netflix and put the ball in their court again? There will be a whole lot of ding-dongings and being pushed around for me again no doubt.

This post has been edited by zainframe: May 7 2018, 12:31 AM

What is known are at least half a dozen netflix servers with "telekommalaysia-isp" names being connected at one point or another (forget for a moment the SG or SYD gateways). And Maxis seems to have no issues with 4k hdr streaming, only TM has issues. So it could be a local connection isssue, assuming there are local gateways with Netflix. TM is never known to throttle local connections, which is puzzling too.

The way to play this is to raise a complaint with Netflix and get them to share how their local gateways are setup. Then we can know what bandwidth they actually have which could be a reason for slow speeds. Problem is Netflix support will not be able, or willing, to share this information. They basically give generic answers and not worth the time. Unless someone has a connection to Netflix corporate, do not see how this can get resolved.

Call 100 and ask technical team to up band with. In my situation a few months ago tm technical team came to my house then they asked their technical support at their hq to up the bandwith to 13. Dont know whats that means. Until now my netflix streaming up to 2160 for 4k movie. No problem at all.

Before that when faced the same problem to play hd and 4k movie.

Thanks Netflix for suggesting that to my Children.

Freaking unifi speed throttle at night

May I just check with everyone with Netflix app on your 4K TV. What is the maximum video speed when you are streaming 4K/Dolby Vision content in Netflix. The highest I see in mine is 15.25Mbps. Is this normal?
