Fibre Query

[Curtyboy]

Hi

I have a query on my line and how long it's meant to take improve line speeds via Dlm. 

I've had a dodgy powerline adapter that put out a lot of noise.  I've disconnected these now and I'm seeing very low errors on my stats but my line speed hasn't increased in over a week.  

Connected at 39999Kb with a max of 67000Kb download and 19999Kb v 21000Kb upload.

My router also reports zero interleaving. 

I gave it a dissconect and power off for 30mins yesterday but nothing has changed. 

Thanks, 

Curt

Give it time. DLM is quick to downgrade, less so to move up. When I was experimenting with switching routers in the past it took upwards of 14 days. 48 hours gets mentioned frequently, but I have never known it to be that quick myself. Unless things have changed, the best guide on the subject of Openreach DLM I have seen remains the one from Zen Internet, ignore the internal stuff and read the bit about Will my line performance improve again?

Hi Curt

I'm sorry to hear this.

The line test has not detected any faults. 

Would it be possible to leave your router connected at the test socket for 48hrs without rebooting the router? We can then check the connection stats to see if DLM starts to increase the speed.

Thanks

Hi Debbie

My intention of this post isn't to complain about the spped for now I just wanted to see if the line looked fine? 

My powerline adapters were causing lots of errors of a pull down on the max sync speed due to noise when they were transfering data. 

Does my line show excess errors or does it look relatively low? If it looks OK I'll just hang fire and let DLM do it's thing before I start moving things around. 

Thanks, 

Curtis

Hi

No errors showing and line tests look fine. I've also ran a test on the copper line and all voltage / resistance levels are also fine.

Thanks

Karl. 

[Curtyboy]

Thanks for confirming. I'll wait and hope that DLM does its job then. 

Many thanks

Curt

No Problem 🙂

So my service has settled down and I can see I am now synced at 54997k download which is much better but can someone confirm there isn't a cap on my service?

The reason I ask is I have run speed tests and I am consistently getting 39.9MBit (which is very flat) and I can't get over this. 

This is running the speed test on ethernet and turning the WiFi off too. 

There isn't any errors showing either and I'm on fast path so not sure why I can't get closer to the maximum speed. 

Any ideas or help would be appreciated as I'm still getting the same speed as I was prior to the increase! 

Thanks, 

Curt

Hi Curt

Thanks for your reply.

Your line is in sync at 54.9mb. Please can you power down the router for a full 30 minutes and then run a speed test following this?

Thanks

Debbie

[Curtyboy]

Thank you Debbie.  I'll try when I'm back at home Friday and let you know.

Thanks,

Curt

Hi Curtyboy,

Ok thank you 🙂

Thanks

So the line been really good until now, rock solid with zero errors and disconnections. 

Over the last few weeks I've noticed the snr jumping around and errors have been happening and totting up. 

Last night I was gaming and kept having dropped packets and short term disconnections and the errors rates were high.

The line has disconnected a few times tonight and and the snr is still jumping around.

I have a feeling dlm is going to kick back in tonight but wondered could you check your end to see if there are any obvious issues your end. 

Thanks

Hi Curtyboy,

I'm sorry to hear this and I'll take another look now. I've run a test on the line which has detected a potential fault towards the property.

Just to confirm, does your master socket have a test socket? Are you experiencing any issues with the voice service such as noise on the line or no dial tone?

Thanks

[Curtyboy]

Hi Michelle

I checked yesterday and couldn't hear any noise on the line and the dial tone was fine.

I think I have a test socket in kitchen so will have to check.

What does the test you have run look for?

Thanks

Curtis

Hi Curtis,

Ok thanks and please let us know how you get on. The line test will help us determine which engineer would be required for example line or engineer visit to the property. If the line test is clear at the test socket then we can offer further advice.

Thanks

[Curtyboy]

Hi Michelle
Thanks for the reply. It will be tricky as a run a modem that links to a router and my test socket is miles away. I'll have to get myself a long ethernet cable to link them both as a temp measure.
Out of interest can the test be run if I just remove the internal wiring without the vdsl being connected?
My speed has dropped overnight due to DLM kicking in but that's to be expected.
Thanks
Curt

Hi Curtyboy,

Yes, we can re-run the line test again with no equipment connected to the line and the faceplate removed (if the master socket has a test socket) Would it be possible to do this at some point this morning? We would need around 30 minutes to complete the test.

Thanks

[Curtyboy]

Hi Michelle

Are you able to run the test tomorrow if I unplug and confirm please? 

Many thanks

Curtis

[ferguson]

You will have to wait until Monday at the earliest now, the OCE are not here at weekends.

[OCE_Debbie]

Hi Curtis

Apologies for the delay.

I can run the test today, will this be ok? (just let me know what time is best)

Thanks

Debbie
