Speed Throttling on FTTP connection

Clint_1701-A — Mon, 29 May 2023 08:33:35 GMT

Weird issue on my FTTP connection since moving from 145Mbps to 300Mbps.

Whenever I download anything (wired or wireless) it starts off as it should around 35-38MBps and then will start going down to about 1-2MBps. I have a 3 computers and tried it on each to rule out a local computer issue but no, same problem exists for all 3.

I have rebooted the routed twice, tried disconnecting all other connected devices leaving just 1 but still the same.

For example, I will be downloading a game through steam - it initially creeps up to about 37MBps which is fine, but then will drop to 0 for about 10-20 secs and then it will start to edge back up but maybe to about 15MBps and then it will do it again and next time no more than 2MBps.

This problem exists with any site with a large download, so it can't be every site on the internet, the problem has to be more of a local ISP / BT exchange issue for sure.

This is all very frustrating and to me I believe that my connection is being throttled at the ISP end somehow or failing that I have a faulty router. I will swap out the plusnet hub2 router with an older hub1 type and see if that is any better and will let you know the results.

If anyone at plusnet sees this, can you provide any further help at all?

Sorry, it's late at night and I realised the subject and first line should read Full Fibre FTTP not FTTC

Hi Baldrick,

I clicked the thumb as you requested but it has marked it as fixing my problem, it's only fixed my typo lol.

Can you remove this?

Thank you

I replaced my Plusnet Hub2 with an Archer VR600 V1 in the end and got it working fine in the end after remembering it no longer needs to act as a modem, as the BT ONN box does this.

Anyway, long story short, the problem still exists

At a loss as this is so frustrating as waiting for a game to download is no quicker as to when I was on 145Mbps (albeit a tad slower).

I have put my plusnet router back in place now as the archer is too old, although it's wifi is a lot better.

Help Plusnet!!

What does a wired speedtest using the Ookla tester ( speedtest.net ) show ?

Re: Speed Throttling on FTTP connection

Clint_1701-A — Mon, 29 May 2023 12:21:23 GMT

Hey @MisterW

Weirdly on speedtest.net it shows the speed as it should be.

The problem I am having is when downloading any large files from anywhere, the speed starts to drop off after about 30 seconds or so and as said, this happens on any computer connected to it.

Very frustrating...

Re: Speed Throttling on FTTP connection

MisterW — Mon, 29 May 2023 12:25:22 GMT

In that case I would suggest that the limitation is the speed at which the downloaded data can be stored.

Clint_1701-A — Mon, 29 May 2023 12:30:36 GMT

No point in having a fast connection if that is the case, as this is the whole purpose of having this faster speed, but I value your response @MisterW

There must be something throttling this at the exchange end in my opinion.

Oh well, I live in hope that this improves at some point, especially when I come to download "Starfield" upon release later in the year!

Hey @Gandalf

Thank you for running the tests on my line and confirming nothing is wrong.

I will just have to live in hope that this improves in time then.

Thanks for all for your responses

fwiw, what are you using to download these big files?

How big are the files?

If it is a Windows PC, try temporarily turning off any antivirus/security software you may be using to see if it makes any difference?

Is it a Dell branded laptop?

@Clint_1701-A

PlusNet do not throttle traffic - nor do OpenReach

Hi @bill888

These files are from multiple sources, from Steam, Epic Games, GOG Galaxy, list goes on...

I use Panda Dome and I have turned this off but still the problem exists.

No to a dell branded laptop. I have multiple self built PCs as this is what I do for a living and it happens on them all unfortunately

I will just put up with it for now, but appreciate your assistance in this matter.

Hi @bmc

Thank you for this, duly noted

I thought they didn't, it's just what's happening seems to point to it but hey ho must be something else...

Appreciate your comment though - thank you!

fwiw, try downloading this Microsoft image for Office to see if it slows down. It is 4.4GB in size.

Hey @bill888

Just tried it and surprisingly it held it at a consistent 36MBps and towards the latter end it then dropped to 31MBps for a bit then back to 36 (which is expected due to congestion etc)

I will keep trying this though and will let you know should it change, I wonder if it's more a problem at the games app end then...

Re: Speed Throttling on FTTP connection

bill888 — Mon, 29 May 2023 18:33:16 GMT

Excuse my ignorance, but are the games downloaded using a web browser like any other single file, or retrieved by using some other dedicated software(s)?

Re: Speed Throttling on FTTP connection

Clint_1701-A — Mon, 29 May 2023 18:27:43 GMT

@bill888

Steam, GOG, Epic - all through their individual programs, not through a web browser.

Re: Speed Throttling on FTTP connection

bill888 — Mon, 29 May 2023 18:38:34 GMT

A bit of a long shot, but do any of those individual programs allow you to choose a different download server location?

eg. USA, EU or UK etc
