Poor Netflix Speed on 3 Home Broadband


[link to this post]
 
Hi all.

Took delivery of a Huawei B535 router from Three earlier today. I had no problems setting it all up and the handful of speed tests I've done both via ethernet and WiFi have showed speeds of 35-40mbps down and 28mbps up.

However, I've just sat down to watch Netflix and got lots of buffering and low-quality video, the likes of which I've never experiences with Virgin Media. I've just done a couple of speed tests within the Netflix app on the Nvidia Shield TV (via ethernet/homeplug) and it's showing my connection speed as a mere 2-3Mbps!!

Presumably this must be some sort of network issue but does anyone have any experience of this?

You should try a speed test on this site as well. Your speeds on mobile can change a lot as time goes on as load changes as people use their devices.

I have done and they're basically the same as speedtest.net. Don't seem to have any problems with YouTube or Amazon Prime on the same device.

Edit: if I ping Netflix, I get 100% packet loss. Some problem between me and Netflix, evidently..

Have you tried fast.com which is provided by Netflix and see if it's same story?

Yeah, earlier that was giving me garbage speeds too. I've subsequently rebooted the router and the speeds are far more respectable albeit not quite on a par with the speeds I've had from the tester on this site and speedtest.net etc.

My Nvidia Shield TV is connected by a cable albeit via Homeplug. Previously that would top out at about 50Mbps (ancient DEVOLO units) but now seems to be topping out under 20Mbps. Can't see why it would have dropped so much by virtue of switching between the ancient VM Superhub and this new Huawei B535?

As an aside, I've noticed that the IP addresses I'm now getting identify me being in various places in the South East of England (and now Leeds) but I'm in Cardiff. I suppose that's just the way it works with 3?

Have you tried netflix on another device? If so, is the in app tester similar to the Shield tv device. I believe you can test it on the android/IOS Netflix app if not already.

Yep test the netflix speed on another device connected to the b535 to prove whether it might be the shield or the devolo. And try the shield on wifi and see what speed that gets, again to prove whether it might be the devolo or not. process of elimination. It sounds like it is probably related to the devolo that the shield is plugged into.

I'd also recommend changing your DNS settings as the THREE DNS is really limiting. I've found using 1.1.1.1 as primary and 208.67.222,220 as secondary works wonders for finding websites far quicker.

I would get out while you can. Three's network has been in a steady state of decline since at least April 2019. Just see the proof on Twitter:

I haven't time to spend on a twitter thread, but I doubt if it will in any way present a balanced view. Meaning "proof" is rather over-stating its position.

I have been entirely on Three since the end of 2018 and haven't noticed any decline at all.

I assume you didn't find that thread until after 2 July 2019 tongue:-

Three is also spending a LOT of money replacing a significant amount of its core network and transmission equipment with that from a different vendor. (See twitter feeds from people whom know). In areas where the network rebuild is complete, significant improvement has been seen in capacity. This may be one of a few reasons for the delay with a larger 5G roll out.

From my experience with a 3 sim for a year now it takes a good while for the Netflix speed to ramp up when you start watching and also they heavily traffic manage Netflix traffic when they need to, literally Ive done a speed test and Netflix stream within seconds of each other and speed test is fine and netflix struggles to get to even a HD stream - off peak and usually in the day time in my residential neighborhood its UHD all the way. Between say 6-11pm its pretty bad. But its been a lifesaver from my 4Mb ADSL, but Cityfibre due here within the next 6 months or less so happy days.

Similar thing with me, had 3 4G and B535 since Friday, put it up in the loft , decent signal up there.

With it on 4G i can get about 20-30 down and 20 up.

With it on 3G i get about 22 down and 2-4 up.

But with Netflix, its pretty good streams 4K on 3G but on 4G its terrible, the throughput is shocking, cant be the wi fi as its fine on 3G.

Speed tests on my pc with 4G are good, browsing is good. so no idea what it is.

Have a few aerials coming in the next few weeks, will see if they make a difference,

Well, if you did find time to read that Twitter account, then you'd see that there are quite a few people who've noticed a steady decline in speeds in the past few months.

I gave up in the end (having had exactly the same experience as them) and moved to Vodafone, where my speeds have improved dramatically.

If Three are truthfully spending a fortune on upgrading their network, then they need to be more upfront with their customers. It started out well enough with them (back in July, as you correctly discovered) but deteriorated to a point over Christmas where I was barely getting 0.01. All I ever saw were p*ss poor speeds every day.

I'm glad it's working for you though. I just can't rely on them.

Unfortunately, Three are not very open or honest when asked about their traffic shaping, I’m guessing for fear of appearing inferior to their competitors.

The closest you’ll get, which was only revealed after OfCom gave them a telling off:
http://support.three.co.uk/SRVS/CGI-BIN/WEBISAPI.DLL...

From experience they apply the “Go roam around the world’ traffic shaping in areas in the UK when experiencing congestion, typically from 4pm to 11pm. However according to their documents, no such shaping is used in practice, go figure!

That is quite disturbing. they screw with the speed of vpn's.....at the exact time you need them most, when abroad on unknown networks! I was seriously looking at switching to 3 due to their 5g spectrum and good prices, but this is exactly the sort of thing that would royally p me off so I will likely avoid them now and either stick with EE or check out voda since EE are currently intent on pricing themselves out of the market for 5g.

I think EE has a leading position on 5G today and prices reflect it.

I've noticed during the past week that in the evening when everyone on Three in my area is using the same mast I can struggle to stream you-tube. Obviously more bandwidth is required from Three.

Depends what you mean. "Bandwidth" on a radio system consists of two things:
1) Radio capacity between your device and the mast
2) Connectivity between the mast and the core network

The majority of cellular systems around the world are limited at 1. Governments only have limited amount of radio capacity and licence this capacity. Networks bid for capacity, and then make a cost decision about where to deploy. You may find the radio spectrum in your area is saturated for the number of users. Three may have additional capacity they can deploy, or they might have deployed all they own.

Radio isn't really a suitable medium for broadband in high use areas (e.g. towns/cities) for this reason. The ideas behind 5G might change the parameters if lots more micro-cells are deployed, but that will take a long time.

I presumed the reason it slows down in the evening is not because my connection with the mast is limited but the amount of bandwidth available from the mast is and when everyone local to me is connected to it? (So it effectively causes contention issues the same way as an oversubscribed virgin media street cabinet)

Just ran a speed test 4:23pm an amazing 4.5Mbps.........strange how at 12pm I was getting a constant 55Mbps isn't it?

Nope, generally the backhaul is not the limiting factor. But this is a complex area, and it is hard to debug.

You will find most masts are 3 sector, so if you can walk around the mast (easier if you can see it) you might find a lower loaded sector and have noticable speed increase. All 3 sectors will be using the same backhaul.

So the slow down in the evening is more likely Three traffic shaping and deliberately throttling bandwidth?

Coincedently last night was for me one of the worst ive experienced, about 7:30pm I wanted to watch something on Netflix and I was hardly getting 250KB/s, at the same time while Netflix was playing I ran a speed test and got the usual peak evening low of 20Mb/s.
This all usually clears by about 10:30pm onwards when I normally watch things and again it was fine.

If its only Netflix that slows down, then time for a complaint to Ofcom.

Don't just assume speed tests, try downloading the large files from the main site.
