Broadband slower than surrounding houses

ksp100 — Mon, 15 Mar 2021 09:23:18 GMT

Hi,

I was one of the first in our street to connect through Infinity, first at 38mpbs and then upgraded to 76mpbs, although i don't think I ever got an actual download speed above about 67mbps. We are connected via an underground cable.

We had a few problems on the phone line before Christmas with crackles but after a few days it cleared (did someone else report something or did it 'dry out' - don't know!) and therefore I never pursued it.

At that time, I looked at the broadband speed and noted it was lower than previously. My router now consistently says I am connecting as follows:

Line Statistics

	Downstream	Upstream
Actual Rate	54997	Kbps	11329	Kbps
Attainable Rate	59837	Kbps	11329	Kbps

If I use the bt wholesale broadband checker website, I get the following info:

Featured Products Downstream Line Rate(Mbps) Upstream Line Rate (Mbps) Downstream HandbackThreshold(Mbps) WBC FTTC Availability Date WBC SOGEA Availability Date Left in JumperHigh Low High Low VDSL Range A (Clean)

VDSL Range B (Impacted)

70.8

19.3

12.7

Available

68.7

11.5

Available

If I use it to view searching by address, I get the same info. If I search for immediate neighbours either side, I get the same details, but if I search for an address a few doors up or down, or those on the opposite side of the street, and they are all still on the same cabinet, they get this:

Featured Products Downstream Line Rate(Mbps) Upstream Line Rate (Mbps) Downstream HandbackThreshold(Mbps) WBC FTTC Availability Date WBC SOGEA Availability DateHigh Low High Low VDSL Range A (Clean)

VDSL Range B (Impacted)

80	60	20	19	54	Available	Available
79.5	55	20	17	46.9	Available	Available

Does this imply something wrong with the cabling to our little section of the street? I should add that as fttc is not planned by openreach to our area, an independent company in the South East has recently installed it to the town. Our set of house numbers are not included in the list of those that can 'have' it, which implies they know something!

Any suggestions on what to do? I can imagine the first response on a call centre will be that you are getting what the line claims it can deliver. But it appears the claim drops to match the condition of any connection?

Thanks for any help or suggestions.

Not quite sure why this was moved as it is about a FTTC broadband connection not FTTP, but anyway, I spotted an error in my original email. Where I said "I should add that as fttc is not planned by openreach to our area..." I meant to say "I should add that as fttp is not planned by openreach to our area...".

Not entirely sure what you mean about not getting FTTC, you currently have an FTTC connection.

Are you a BT broadband customer?

You can't compare the estimated speeds of houses that are a different distance from the cabinet, just few metres makes a difference.

You appear to be on a 55M downstream profile (but oddly the Upstream figure doesn't tally) with a maximum possible speed of approx 60M. Either you are on an incorrect profile or DLM has intervened and capped your speed.

Posts crossed, I moved your post as the board you posted on is for ADSL, you have a VDSL (FTTC) connection and this is the correct board for FTTC and FTTP.

Sorry for the confusion - I thought the BT Fibre broadband was just for FTTP; my bad!

Yes, I am a BT Broadband customer.

Why would the downstream speed not try to increase up to something close to the line capacity (i.e. 60mpbs)? My router last reconnected itself 127 hours ago and prior to that I think it got to about 600hours (although it could be the timer in the router just reset rather than the line!). If it helps, I can post the DSL line stats.

Equally, why would the upstream hit the attainable rate of 11mbps and the line not think it is capable of more?

A line is not capable of thinking. You will get the speed the characteristics of your line support barring any fault.

Full line statistics would indicate if there was a problem.

As already stated, your line is either mis-provisioned at the old fibre1 download cap or DLM has banded your line at some point due to instability

nothing in the stats that shows internet connection time not system connection time which is different

So how can we get this reset given that BT's sales website now indicates that we can only get Fibre 1 up to 50mpbs and I suspect if I ring them they are just going to quote their website?; this despite being on and getting Fibre 2 speeds until about six months ago.

Re: Broadband slower than surrounding houses

licquorice — Tue, 16 Mar 2021 08:39:15 GMT

I suspect DLM has banded your line due to the earlier line problem. It can often take a very long time for banding to be released. BT won't be interested as your speed is very close to maximum in any case. To be perfectly honest, you won't notice the difference between 55M and 60M in the real world anyway.

Re: Broadband slower than surrounding houses

ksp100 — Tue, 16 Mar 2021 09:04:25 GMT

Thanks. I am just concerned that given we used to be getting mid 60s actual download speeds and now we are seeing low 50s and the only option on the BT website now is to get Fibre 1 with a maximum of 50 that our speed here is getting slower and slower over time.

I was on Fibre 2 and they have recently moved me to Halo, I am paying now paying way over the odds against the basic Fibre 1/2 option for no benefit. But if i recontract, I am committing to a max 50Mbps (presumably with my line profiled to a maximum of what it is currently doing) with a guarantee of only 32Mbps whilst every other house around us (we live right in the centre of an housing estate) is guaranteed 62Mbps.

Re: Broadband slower than surrounding houses

ksp100 — Thu, 18 Mar 2021 14:16:11 GMT

So I 've done a bit more digging. Firstly, I have found the terms that I signed up for back in 2017. I was moved from the original Infinity 38Mbps systems to Infinity 2 with an estimated 45-65Mbps download speed, with a guarantee of 40mbps.

I have also discovered that speedtest.net records your results and from that I have consistent records up to 22 December 2020 where download speed fluctuated between 62.9 and 67 and upload 10.4. Since the problem at the beginning of the year when it dipped to 3.28 (download) and 2.80 (upload) where a router reset brought it back to life, the fastest I am now ever seeing is ~52Mbps and 10.44Mbps. Clearly something has happened on our local network which resulted in the drop.

But worryingly, according to the BT website now our address is now only able to get up to 50Mbps with a guarantee of 30mbps. So rather than addressing faults, the approach seems to be lower the bar?? Is there anyone I can discuss this with in BT who can liaise with Openreach. The call centres haven't been any help as they just quote the current figures from the BT website. Thanks in advance.

Obviously crosstalk as more users have been added.

Re: Broadband slower than surrounding houses

ksp100 — Thu, 18 Mar 2021 18:41:19 GMT

But suddenly and with such a large drop? And this isn't like at the start of lockdown when suddenly everyone went to home working?

It couldn't have been affected by an independent company who is now running fibre through the Openreach ducts to provide some properties with FTTP, could it?

ksp100 — Fri, 19 Mar 2021 06:43:31 GMT

Sorry licquorice. Do you mean no to my question about whether it could be affected by work done by the third party in the ducts or to an earlier comment?

Re: Broadband slower than surrounding houses

ksp100 — Fri, 19 Mar 2021 07:09:59 GMT

Also meant to ask licquorice, do you still think given the attainable speed is ~59 and the actual speed is ~55 (and according the BT diagnostics test that my ip profile is 53.17) that my profile has been capped?

Licquorice - sorry for the plethora of posts! I have just reviewed the stats page of my modem and it now states this:

It now claims the attainable rate is ~67 but is still firmly locked on 55 connection.
