Very Slow Fiber speed after upgrade from ADSL

[#1]

No its not. I will update the ticket once I had check my diary for once I'm back from holiday.

Looking at my stats from the router, I have a Data rate of 6400 and a Maximum data rate of 48268. Why are these so different? Is the maximum data rate my sync speed? And then is my speed capped to 6400? Is there any faults showing on the line? Could the router be faulty? Or do the attenuation and noise margin stats point to a line fault? Also for the noise margin I have 6.3 / 30.6. I take in 6.3 is for upload and 30.6 is down. Should these be so different?

Thanks for getting back to us @wmackay

The data rate refers to the current rate your router is connected to the cabinet at whereas the maximum data rate is what your line may be able to achieve if it was clear of faults.

Our tests aren't showing any cause for this but the high SNR margin on the downstream will be why the sync speed is poor.

It may be at the time your router last reconnected there was a high amount of noise on the line and as a result, the noise margin ended up higher to try to keep the connection stable.

I'd recommend trying to reboot the router to see if that brings the speed up. If not then just let us know your availability for an engineer and we'll get that booked for you.

As I am on holiday I won't be able to reboot the until I am home at the weekend. If there was noise on the line when the router last reconnected and then the noise had gone away, would the DLM system not cause the line to reconnect between 3 - 5 am? As it seems I have frequent reconnect between 3 - 5 am, which I guess are caused by the DLM?

Could the issue be a faulty router?

Also why is the sync speed from my router 6.4Mbps so different that the sync speed you get from your testing 40Mbps?

Thanks for getting back to us @wmackay

DLM would only force a reconnection if the restriction has been caused by DLM. As your current profile is "0.128M-40M Downstream, Error Protection Off - 0.128M-10M Upstream, Error Protection Off".

Having said that it appears that your router's connection speeds have gone back up this morning so you may have had a power cut or maybe some planned maintenance that dropped the connection.

Let us know when your back in the property so we can confirm if you're seeing an increase on our end

I will check the speed once I get home.

It is possible to get a GEA test run on my line and results posted with radius ( reconnects graph) result as well.

I wouldn't worry about it listing there being banding on the line. As we can see that you're in sync well above the banding it's more than likely an out of date profile result.

Your RADIUS logs show the below:

Please let us know what speeds you're seeing your side.

Thank you for your reply. I will check when I am home tomorrow.

[#9]

No worries @wmackay. 

Let us know what you find out. 

All the best,

After a reboot my speed on both ethernet and wifi is above 30Mbps. and my SNR margin has come down to 9.8 from 30.6. so fingers crossed it seems to be fixed 

[#11]

That's great to hear, @wmackay

Let us know if there's anything else you need.

Best wishes

My speed is still above 30Mbps so happy the issue is fixed. Though I'm still not sure what fixed it, as on

Tuesday 17th Sept - Openreach replaced an old external junction box, speed came up to 30Mbps until Thursday 18th then back to 5Mbps

Thursday 26th Sept - Openreach engineer tested the line at cabinet and master socket said the speed was fine. But after he left it was still 5Mbps.

Saturday 28th Sept - informed that was on a hot VLAN and this would be fixed by Monday 30th Sept.

Sunday 6th Oct - tested the speed and still on only 5Mbps, SNR margin 30.6, uptime on the connection only 8hrs.

Saturday 12th Oct - speed still only 5Mbps on the test socket. Moved the router to internal socket and filter by MK4 VDSL faceplate in NTE5C and speed 35Mbps and SNR margin 9.8.

Nothing has changed from Monday 30th Sept to Saturday 12th Oct. Then by moving the router to the internal socket and using the faceplate has fixed it?!? Did anything change on Plusnet / openreach side? So was the filter supplied with PlusNet One Hub fault? I don't want to test it as I seem to have a stable connection.

Thanks for getting back to us @wmackay Doing a bit of digging it looks like your speeds were restricted to max 6mbps by an old profile on our side which updated to 38.4mbps on the 8th October.

Looking at your connection log (Below) I suspect that when you moved your router back to the internal socket on the 12th October, this disconnection caused the profile from the 8th October to take effect.

I hope this helps.

[#14]

Thanks that cleared that up.

[#15]

Cool. Let us know if there's anything else we can help with.
