Few days of very slow connection ADSL

IanSn — Thu, 11 Aug 2022 10:55:05 GMT

ADSL usually around 17Mbps. Suddenly it dropped. Last few days around 3.7

Test says profile speed is 4.1

(Had line checked and engineer while back and all was well till now.)

Line is quiet.

Ethernet speedtests / router below

Hopefully a temporary glitch!

@IanSn Is your D/S noise margin usually that high? I suspect something is wrong - you've only had this DSL connection for 3 days 4hours.

@IanSn

You probably should have blacked out your personal details!!!

What does the following say for your line. Post a screen image without your phone number.

@IanSn You could try a single reboot of the router (power off and on again) to see if the downstream SNRM comes down to a sensible level, although there may well be a line fault as the upstream stats also look to be very poor. You will probably have to report a speed fault.

@jab1 @bmc @RealAleMadrid

Oops, forgot to fade my details...

Uptime date is exact to a powercut. Lasted 1 to 2 mins.

This is stats from around June so, yes, its different! -

7 - Data rate: 944/22191
8 - Maximum data rate: 1196/24552
9 - Noise margin: 5.7/5.0
10 - Line attenuation: 7.7/15.5

BTbroadband -

Not sure how to report a fault.

@IanSn So long as there is no noise on the phone (Quiet Line Test 17070, option 2), report a BB fault here: https://www.plus.net/help/report-a-problem/broadband/

@IanSn

To get the normal ADSL speed of around 17 you must be close to the cabinet.

If ADSL suits you needs then fair enough but faster speeds are available on FTTC if required.

@bmc looking at the attenuation figures - and the BT checker above, the OP is clearly close to the exchange/cab.

Re: Few days of very slow connection ADSL

IanSn — Thu, 11 Aug 2022 13:20:33 GMT

Done

Re: Few days of very slow connection ADSL

IanSn — Thu, 11 Aug 2022 13:22:35 GMT

Can see the cab from my window, exchange is just down the road!

Thought so, Ian.😀

Lovely lady on phone. Looks like it may have been the powercut as everything had been fine up to that date/time then sudden drop, but changing SNR anyway, hopefully no need for engineer. Keeping an eye on it.

Thanks to all for help.

A side query. I wonder if VPN makes any difference to these things. There's an 'accelerator' on the one I use. I know very little about these things. Could that interfere with speed, etc?

Re: Few days of very slow connection ADSL

jab1 — Thu, 11 Aug 2022 14:31:06 GMT

@IanSn Give it a week (max) and if the SNR hasn't dropped back/speed increased, come back and ask on here for one of the Help Team to reset your profile.

If you ran the speed test via VPN, that could have implications, but the 'observed speed' on the BTW report suggests that it did not have any significant impact. NEVER use VPNs when carrying out any tests/investigations.

Re: Few days of very slow connection ADSL

IanSn — Thu, 11 Aug 2022 15:36:55 GMT

Thanks, John, will do.

I have no idea what 'accelerator' is or does. Or how. I switched it off anyway as it seemed unnecessary.

No, VPN off for tests!

Re: Few days of very slow connection ADSL

Had a rash of power-cuts this morning - that's really going to help... 🙄

Re: Few days of very slow connection ADSL

jab1 — Fri, 12 Aug 2022 16:27:59 GMT

Sorry, Ian, but it won't.

Re: Few days of very slow connection ADSL

IanSn — Fri, 12 Aug 2022 16:33:41 GMT

Amazingly frustrating! One after another. Seems to have settled this evening.

Does this mean back to square one, or just wait a bit longer?

Re: Few days of very slow connection ADSL

jab1 — Fri, 12 Aug 2022 16:39:26 GMT

@IanSn my suggestion, for what it's worth - wait another day, and if there is no change either contact PN as suggested or post back here - I have a 'check-list' we could use to determine if it was just the power cut, or something a bit more major.

Re: Few days of very slow connection ADSL

IanSn — Fri, 12 Aug 2022 17:05:03 GMT

Yes, sounds sensible.

Thanks, it may just have been a coincidence that troubles started at same time as power-cut. I've been hoping it wasn't.

Speed is still slow this evening...

Re: Few days of very slow connection ADSL

IanSn — Mon, 15 Aug 2022 16:44:50 GMT

So. No change.

Tests results don't mean much to me, not my area of expertise, but I don't understand why I'm seeing these results.

I have a Q open on this but, before I get back to that, I need to know what I'm talking about, and why this report says there is no problem. There is.

I know there was a reset and I have to wait, but the line seems to be very stable - at a very slow speed.

Over 10 years with PlusNet, at these premises, I always had far better speeds than this so I know this isn't correct. Why is my profile set at this?

Other tests I've run (on this thread) have numbers up to 17.5. I accept I'm not likely to get that but 3.75?

There was an engineer here back in June sometime, he went to the exchange and did something with a card. It was back to normal after that. I didn't do tests then as everything seemed fine.
