Constant Fiber Dropping and Slow speed

[#1]

Been getting really slow speed and constant dropped connections for approaching three weeks now, admittedly i have only reported this two weeks ago now, as i assumed it was weather related anyway.

Setup:

Im very close to the cabinets Plus net put me at about 147m away,

Cabinet -- 60M --> Pole -- 40M --> Pole ( Support Only No connection) -- 20m --> External Joint on House -- 10M --> Master Socket.

Master socket had a mark 3 filtered face plate and one filtered extension.

Previously i had been getting the full 80M down and 20M up for probably over 7 Years and three different providers (not that makes a different) I have been with Plus net close to 9 Month before any problems.

Report: 

After a week of problems I reported this to Plus net who confirmed the drop outs but said the line passes all tests but after a week sent an Open Reach engineer out.

For the offset he was hell bent on blaming everything in my house and in the end replaced the master socket and filter with the new MK4 and reset the DLM, leaving the extension disconnect (My fault obviously as 10 years its been connected no problems)

Anyway all looked good the Modem reSynced at full rate and he left (I assuming a bill now as a customer fault and quite rightly so if the line was fixed) but not even 24hr later the line is back down to what it was.

Here is my line states from my Draytek Router

Downstream Upstream

I previously i had a SNR of around 11 each way but got the full 80down and 20up but i have notice the Attenuation has jumped from 6 up to 26.

As the Open Reach engineer didn't like my router i recently connected the Plus net supplied one to see it it makes a blind bit of difference.

Again stats are very similar  to the draytek.

Im annoyed as

1: My internet i hardly usable due to drop outs.

2: I bet i get a charge applied

3: I'm no further forward 

Admittedly this is not Plus nets fault but I'm not getting anywhere and communications seem to be all front line workers from a script. And commutations is very Lax

Hi @duckettp, sorry to hear you're having broadband issues.

I have updated the fault ticket, please click here to view my response.

Please let us know on this thread once you've replied back to the above ticket so we can pick it up as soon as possible.

[#3]

Another engineer visit scheduled for the 12th am slot hopefully they will see the fault now it appear mainly over night and morning 

[#4]

@duckettp - please let us know how this appointment goes and, if needed, if we can assist further. 

Thanks, 

MoR

Just had the Open reach engineer turn up, plugged his test meter in and said clear as day there is a cable break about 60M away.

He complained about the previous engineer and how come he couldn't spot it  as it was clear as day.

Now waiting on a cherry picker to climb the pole as it doesn't appear the post is in serviceable condition to climb, Happy that the fault has been identified on there network as i have been stressing so much about this after the first engineer blamed everything with my equipment.

Just now to wait for the resolution. At least i can breath a sigh of relief 

[#6]

Thanks for the update, @duckettp.

We're pleased to hear that the disconnection has been identified and that it's on the way to being repaired.

Please let us all know how it goes after the cherry picker's been.

[#7]

Right all now been repaired line stats have now increased:

So looking rather good from a sync perspective.

Though speed tests are reporting 39/17 ish is this something that might increase in time? The open reach guy did reset the line so hopefully though-put will increase.

[#8]

Thanks for getting back to us @duckettp.

A speed of 39mbps is less than half of the lower estimate for the line and so it'd indicate to me that there could still be an issue.

Are you able to run a speed test and post the results?

[#9]

I would happen to agree, after doing the BT wholesale speed test it seems to suggest my IP profile is capped to 20 though im not sure how reliable that is 

[#10]

I've just performed a GEA test on the line and unfortunately we're still seeing evidence of a high resistance cable joint. I've rejected the clear on the fault from today's engineer visit and have requested further information letting them know what the test results show. 

[#11]

Speed test results from a wired PC 

1. Downstream Test: -provides background information.

Download Speed
33.81 Mbps

0 Mbps 77.43 Mbps
Max Achievable Speed

Download speedachieved during the test was - 33.81 Mbps
For your connection, the acceptable range of speedsis 40 Mbps-77.43 Mbps .
Additional Information:
IP Profile for your line is - 77.43 Mbps

2. Upstream Test: -provides background information.

Upload Speed
27.65 Mbps

0 Mbps 20 Mbps
Max Achievable Speed

Upload speed achieved during the test was - 27.65Mbps
Additional Information:
Upstream Rate IP profile on your line is - 20 Mbps

This test was not conclusive and further testing is required.This might be useful for your Broadband Service Provider to investigate the fault.
Please close the window using 'Exit' button and contact your ISP for further assistance with these results.

Please visit the FAQ if you are unable to understand the test results.

[#12]

Hi @duckettp,

Thank you for providing that test result, I'm sorry for any inconvenience that this fault is causing you.

Our suppliers have advised that we need to arrange another engineer visit so that this may be investigated further. Please can you add your availability to the ticket here? If you add another post to this thread once you've done this, we'll pick this back up and get that booked in for you.

[#13]

I am a little concerned now as the Modem is reporting a nice and stable sync at 80/20 but the thoughput is less than half almost bang on 40. Could this be a stuck Bras profile or congestion? The line is still showing some noise on a quiet line test but im pretty sure the Openreach engineer check everythuing before he left. Im just concerned about getting an engineering out again in case they dont find anything this time, has everything be check that can be?

[#14]

Hi @duckettp 

Just checking - you are measuring your throughput via a wired connection? 

Thanks, 

MoR

[#15]

Yep tried with my Draytek router which is a little bit of a complex network setup and with the Plusnet supplied router with a laptop wired directly with nothing else. both show the Sync rate at 80/20 but speed tests are 40/20, and this is about 20 speed tests over different parts of the day.

If it wasn't so constant at 40 I would guess their is a problem but this seems more like a cap
