Fibre Broadband speeds still low even after line fault cleared?

[#1]

Over the past few months I have been experiencing speed problems (See attached graph generated by SamKnows).

The graph needs some explanation:

From start of Graph (01 September) I was using an Huawei HG612 (3B) with an updated firmware so that I can observe line stats.

Around 18 September I noticed a large speed drop. Examining the line stats I noticed that the Download Interleave depth had changed from 1 to 959. The Max attainable line speed was still showing 55572kbps.

The dip in speed ~16 - ~20 September was caused when I was trying a Draytek Vigor 130. The attainable line speed of the Vigor was lower than the Huwawi with the Interleave depth ~650.

I continued to use the Huwawi, until I suffered another speed drop, where upon I switched to the HubOne.

The dip in speed on 08 November, I initially thought was a new contract mess-up, but my line showed up faulty. Strangely the dip in speed returned the day before the engineer visit.

I had expected some improvement in speed since the line fault was reported as cleared, however this hasn't happened.

Help please.

Thanks for your post @ChrisGn

We've tested your line and we can see that your speeds have dropped but our tests aren't showing any cause for this.

I'd recommend raising a fault by going here and then posting back once you've done so.

This will allow us to get that picked up for you

Where is 'here'?  I expected it to be a link..

[#4]

Oh dear @MatthewWheeler has not put a link in.

I would suggest you put the HG612 Modem back on the line, it is certainly better than the Hub one and probably the Draytek.

There are some serious speed drops showing, I think you have definitely got some fault going on. Not sure how you raise a fault on the member centre, never needed to do one.😃

Thanks for getting back to us @ChrisGn 

Sorry about that, I believe my colleague meant to link you to http://faults.plus.net

[#6]

OK, done that... Fault reported..

[#7]

Hello @ChrisGn,

Thank you for getting back to us and reporting the fault. We have raised this to our supplier and will require an engineer appointment. Please can you add your availability here and update this thread so that we can get this picked up for you.

[#8]

I accidentally closed my ticket... (Thanks for not having 'Are you sure'). Is there any way of getting it back, or do I have to go to the process again?

[#9]

Sorry to hear this happened @ChrisGn, can you update this one for me here and update this thread so I can progress the fault for you.

[#10]

OK, I have agreed to the engineer visit and the possible cost implications if there is no fault found..

[#11]

Thanks for getting back to us @ChrisGn

I've booked the engineer visit for tomorrow 22-11-2019 between 8am and 1pm.

Let us know how it goes.

I have had the engineer visit this morning, it was the same engineer that came to sort out the unbalanced cable fault.

He couldn't understand why he had had to return for a low broadband speed as the line tested OK on his previous visit. He did do further tests however and noticed some marginal bursts of errors that was on the fibre side of things, he said he would sort this out at the cabinet.

One thing that became apparent was that he had expected Plusnet to have performed a DLM reset after the 1st fault was cleared.  I also have no idea if the engineer has done a DLM reset, as he sent me an text message to say he had completed the work at the cabinet and that the job was complete, so I had no chance to ask him.

I have done some tests since:

HubOne DSL Line Stats: Downstream 51.04 Mbps, Upstream 9.995 Mbps.

Ookla: Download 41.09 Mbps, Upload 9.35 Mbps.

BT Wholesale Test:

The max achievable download speed has gone up but actual download speeds are still low and have gone slightly down.

I await your thoughts on the issue.

Hi Chris,

We've got you in sync at 51mb/s from our side which is an improvement from when we raised the fault (45mb/s).

Could you confirm that you're still in the test socket (https://community.plus.net/t5/Library/Testing-From-The-Master-Socket/ba-p/1322242#expose) and that you're running these speed tests via a wired connection with nothing else utilising the bandwidth?

Thanks

Dave

The last tests were done as per my normal setup, i.e. HubOne plugged into master Socket 5C (MK4), Telephone on the end of short fixed extension socket.  PC wired direct to network.

I have just re-done the tests with the same results with the HubOne connected to the Test Socket and the PC directly wired to the HubOne i.e. network totally isolated and no WiFi activity.  All software that could create network traffic (Thunderbird etc) closed.

I have now put the setup back to normal as I can't have the phone disconnected for any length of time at the moment.  Speeds are still the same with the exception that the HubOne now shows DSL Line Stats of download 48.77 Mbps and upload 9.995 Mbps which is hardly surprising due to the multiple disconnects.

Hi @ChrisGn,

What were the speed test results while the router was plugged in to the test socket?
