BT Capping

tnjrad — Fri, 26 Jun 2020 21:30:03 GMT

I have recently upgraded my service on GFast and my download data speed is 140Mb/s but my router stated speed is 388Mb/s, why the difference?

With them speeds, I would guess you're a F100 customer, if so the speeds are as expected, GFast is still FTTC.

The router speed you're looking at is the max speed you're line will handle. If you're on fibre 100, it's capped at around 145mbps.

I have Fibre 250 with Halo2 and my minimum speed guarantee is 150Mb/s

The router is currently connected with a Data Rate of 328Mb/s but the max download speed I can download from any speed test site including BTs is just under 145Mb/s.

The BT Wholesale test site says my IP profile is 319.2Mb/s.

Ahh ok.. in that case if won't be capped at the download speed you're getting. It's probably the device you're downloading on that hitting it's limits. Even if the WiFi card in the device has a theoretical speed of 350mpbs+, there are other factors that will limit the speed... My wife's laptop had a rubbish WiFi card and wouldn't hit over 8mbps on a 140mbps connection. Stuck a WiFi dongle in with 5ghz and it's up to 38mbps... Nowhere near it's it's max...

Also, if you're downloading from P2P your client could be limited in software or the seeder could be limiting upload speeds which again will limit your downloads...

But if BT say that you're getting XXXmbps, that's what you're getting to the hub. Nothing after that is guaranteed

Also, if you've only upgraded in the last few days it can take a couple of weeks for the line to settle due to DLM

Thanks for the replies. The BT Wholesale test says I should be getting a faster download rate than I am which makes me think that there was a cap for Fibre100 that has not been changed for the Fibre250 upgrade.Test Results

have you tried the test using ethernet

Re: BT Capping

tnjrad — Sat, 27 Jun 2020 10:04:18 GMT

Yes, with the GB ethernet directly plugged into the Home Hub. I can transfer large files on the home network at near GB speeds.

I have the exact same problem! Upgraded to fibre 250 from fibre 100, no change in speeds. They sent me and engineer who showed me the line speeds of 272mb downlpad, I told him that's all well and good but my router is giving me 130/140 max wired.

So they send me another router, no difference. Now they're sending me discs as they say that will pickup my wired speed which I know it won't 😕 seen a few posts now like this, bt have a problem

What is your download speed like as a comparison when connected directly to the hub instead of wireless?

What are you using to test this speed? if a pc, what are the capabilities of its network card(s), it sounds like it could possibly be a 100Mbps card and is maxed out already if your getting 272 to the router.

I am using a GB ethernet interface directly connected to the Home Hub and the ethernet link is working at 1Gb/s. I have used different PCs and they are all capable of handling data transfers at GB speeds.

Are you saying your network card is 1Gbps? Whats it set at under properties/ speed and duplex? What speed did you get connecting a cat5e/cat6 directly from the pc to the homehub?

My pc is capable of getting the speeds, used to be with virgin and it happily got over 300mb. There is an issue with the smart hub 2 which bt don't want to acknowledge

Have you turned off smart setup?, have you turned off 2.4ghz wifi and tried connecting to the 5ghz wifi? Are you connecting wired or wireless? Post stats from router and we could be able to help you.

Unless there is a bandwidth restriction in the Home Hub which is very unlikely there is some point in the network where the data rate is capped. This is not a time of day contention issue as similar speeds are available 24/7. Somewhere in the network either in or upstream of the cabinet there is a cap/restriction applied.

Re: BT Capping

tnjrad — Sun, 28 Jun 2020 17:04:47 GMT

To earlier questions the network and storage systems I use can support internal data transfer rates of 1GB/s or close to 100Mbytes/s. 140Mb/s download is way below any internal thresholds. Seeing my line speed rate has more than doubled but the data download rate is exactly the same points to a restriction somewhere upstream. I am a retired telecoms engineer so I do understand the technology even if not familiar with the latest equipment.

@tnjradWhich is it? Internal transfer of 1Gb/s or close to 100Mb/s? There's one heck of a difference there. I think you mean 100 MB/s.

You really need to get your head around the following.

1GB/s (data transfer rate) = 8Gb/s (ISP speeds are quoted in bits (b/s) Megabits (Mb/s) and Gigabits (Gb/s)
