Speed limited and support cannot help

[#1]

I've recently had a number of issues with my fibre connection getting disconnected which resulted in having an openreach engineer out twice. They found a number of faults and my disconnects seem to have gone away. However, since this time my speed has dropped to around half what I achieved before the issues, with any speed test I run seeming to flatline at around 17Mb/s.

Support are stating that the line is fine and showing speeds in excess of 40Mb/s, but this is not the speed I am getting. They say there is no banding on the line. I have tested with multiple routers, cables, test socket etc. all getting the same speed. The only thing I cannot test is the modem, as I only have 1 of these which is a Vigor 130 which is less than a year old.

I've include the vdsl status data from the Vigor, which does show rates inline with what support are saying, but these are not being achieved on any speed test.

Support are now saying that there is nothing more they can do other than escalate to openreach, so I am hoping someone might have some suggestions.

Hello @samcogan82, 

Thanks for reaching out to us here. 

I'm sorry you've had some trouble with your speeds despite assurances from us that your connection was performing within estimates. On testing your connection today you are within estimates, albeit the low end - please go ahead with these steps, 

If that doesn't help, the next thing would be to rule your internal wiring out by plugging the connection into your test socket (which is under the faceplate of your master socket) and seeing if the drops stop. This rules out your internal wiring, face plates and extension sockets as being the cause of these drops. How to locate the test socket and set your connection into it can be found here.

If that doesn't work please raise a fault here and our faults team can pick that up from there. 

Thanks.

Hi, I have indeed tested this using the test socket, as well as using different routers and cables, making no different.

I have raised a fault, which has been open for some time. I have had 2 visits from OpenReach, which does seem to have resolved the connection dropping issue, however I am now faced with this speed issue, which does not seem to be getting anywhere. I was hoping there might be some suggestions on what I can look at beyond the usual use the test socket and a wired connection.

The fact that my modem, and your tests all show the correct speeds, and yet what I am receiving is much lower than that leads me to believe something is being limited somewhere, especially as the speed test show a very flat line for a speed test.

@samcogan82  speed tests are never going to show the same rate as synch speeds and it is the synch speeds that ISP's go on.

Looking at your synch speeds, depending on your equipment, any other device on your network generating traffic, or even other programs running on your device you should be testing around 40Mbps.

What speeds are you "expecting"? Are you getting,and on which device and which test site?

[#5]

I'd be happy with speeds between 35-40Mb/s, which is what I obtained before these issues. What I am getting is between 14 and 17Mb/s, so about half the expected speeds.

I've tested this with a machine directly connected to the router, with nothing else connected to the network, so there shouldn't be any other devices creating load. I have used both speedtest.net and the BT Wholesale speed tests.

[#6]

Are you able to post a pic of the 2nd BTW test, which will show your profile as well as speeds?

And also a pic or link to your speedtest.net?

[#7]

[#8]

I have now also been able to test with a different fibre modem, this again made no difference. I have now changed everything on my side and the problem remains, so I don't believe it can be anything inside the premises.

[#9]

Sorry, I missed your reply on Thursday.

The BTW test shows your profile and should be getting more download speed.

How much more you more you can check on the DSL Checker.

PN have their own profile, that should follow the BTW one, but they have been know to get stuck.

Another possibility is congestion, but then that would give diggerent results at different times of the day. Are you checking when nothing else is running on your device, and other devices are not downloading stuff in the background?

Otherwise I am running out of ideas!

Mybe one of the helpful staff members could help out @Gandalf 

[#10]

No problem, thanks for getting back to me.

Yeah I am testing with everything else disconnected from the network, solely the router, modem and laptop with a wired connection directly into the router. I've tested at all different types of day and get identical results.

I'm also running out of ideas now!

[#11]

The Thinkbroadband speed test tests both single and multi thread. Most speedtesters use multi thread which won't show congestion. If you run this test, both lines should be as close together as possible. TestmyNet also does both tests, but it also allows you to set it to run multiple tests through a time span. when I had problems, I had it set to test every 30 minutes, up to 400 (I think) times and that will give you a good indication of what is going on.

[#12]

I ran the thinkbroadband test and see the lines are pretty much together, so doesn't look like a congestion issue.

[#13]

@Mustrum  said PN have their own profile, that should follow the BTW one, but they have been know to get stuck.

The PlusNet profile is largely not used anymore UNLESS you are on a static IP.

@samcogan82  do you have a static IP ?

Anyway , you can check the PlusNet profile by logging into your member centre account and selecting the Broadband icon. In the 'your broadband service' box that results , it should have a line that says ' Current Line speed'

[#14]

I do have a static IP.

However, looking at the plusnet profile, it seems OK:

[#15 · Accepted solution]

Yes, that looks fine.

It sounds from previous posts that you almost certainly would have, but can you confirm the the PPPoE session will have been dropped and reconnected since the work to fix the original fault. The reason I ask is that any change to the PlusNet profile will only take effect when the PPPoE session is reestablished. The PlusNet profile will likely have dropped to follow any change to the BT profile when the original fault occurred. It will have followed the BT profile back up when the fault was fixed but if it hasnt seen a PPPoE reestablished then any increase wont have taken effect.

Really just clutching at straws...
