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

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.

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

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.

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.

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.

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.
