PLease dont alter as it has worked well

@stathe Looking at those figures, your downstream SNR is much too low for your line attenuation - you need a minimum of 6dB, maybe higher.

I would wait for one of the Help Team to pick this up and carry out some checks.

@jab1 under normal circumstances, I'd agree, but I suspect this line has had a 3db target SNR set to try and get a half-decent speed given the line attenuation. The down side , of course, is that it will be subject to the possibility of more errors.

Without the error stats , its difficult to determine whether that is the problem, but this looks a little like more of a DNS problem.

@stathe have you tried setting DNS servers on the pc rather than using the routers ?

Good point, @MisterW , but with a line that long, it wouldn't take many errors to drop it? Personally, from previous topics by this OP, I would be looking at an FTTC connection - if available - surely this would be more suitable, unless of course the FTTC cab is so far away as to make it unworkable?

It seems internet is still connected but no Plusnet I am not able to get any other

Unfortunately I dont understand

Re: Internet failing

stathe — Mon, 30 Jan 2023 21:24:26 GMT

Mister W you are right about my speeds and it works well most of the time so dont want it altered

Can you please clarify the message?

What indicates that you are still connected?
Whilst "it" says no internet?

Are these the same "it" or different "its"?

What says "no internet"? Your PC? A web browser?

Which router are you using?

What OS is the PC running (if it is the PC / web browser reporting "no internet")?

There are a multitude of circumstances which can give rise to the not so clear statement of symptoms, including, but not limited to...

Noise on the line
Faulty exchange equipment
Overloaded back haul
Failing router
WiFi drop outs
DNS issues - notable with certain router and OS combinations

Broadband is not going to work well if the "phone" line is not working properly.

Please perform a quiet line test - dial 17070 select option 2 using a phone plugged into the test socket behind the face plate of the master socket (ideally this should be a corded phone). The line should be silent. A noisy phone line (or no dial tone) will have a marked adverse impact on the performance of broadband.

If the line is noisy or there is no dial tone, then a PHONE LINE fault needs to be raised with your phone provider. If this is PlusNet, you can report a fault on line using the button below. NB: You need to put your LANDLINE NUMBER after "PHONE" [missing instruction].

Phone Faults

As @jab1 has suggested, this is a very long line at the very limit of ADSL viability - it really is flying by the seat of the pants!

SammyM — Tue, 31 Jan 2023 13:05:08 GMT

@jab1 is correct the SNR is set too low for the line and DLM has reset it to what it should be.

Try it at 6db for now and let us know if the issue is still there.

Re: Internet failing

stathe — Tue, 31 Jan 2023 14:40:47 GMT

The reason it is set so low was to give me a half decent signal I fear that at 6 it will be too slow

Hi @stathe, how are things looking for you today in terms of speeds and stability? I've checked and can see the connection has been up for just over 24 hours now which is good to see.

Re: Internet failing

stathe — Tue, 31 Jan 2023 14:52:55 GMT

I have been through this many times (in my previous Notes no doubt ) I have internet connection but Plusnet disconnects despite still having internet connection, yes .

I then switch of the router and on again

after a minute or so and all is well until maybe tomorrow

Re: Internet failing

stathe — Tue, 31 Jan 2023 14:58:52 GMT

Yes with it set at 3. or thereabouts it stays on but the litle fan on devices is there with a very tiny cross beside it I dont want this raised or I wont be able to do anything We are in the sticks here along way from boxes or exchange

Re: Internet failing

adamwalker — Tue, 31 Jan 2023 15:01:35 GMT

Thanks for getting back to me, has the connection been stable since yesterday and what are speeds looking like today?

Re: Internet failing

stathe — Tue, 31 Jan 2023 15:28:37 GMT

I have a Netgear N600 Dual band Gigabit ADSL2+ Modem Router DGND3700v2 which has worked well We have lots connec ted to it around the house As I say the internet stays connected but no Plusnet In the top corner of phone and pad it shows the fan for internet with a tiny cross near shows a fan with a tiny cross

I am 87 and not really at all computer literate And a long way from boxes and excrea have left and joined mobile outfits or a radio option (in sightline)

I want to stay to retain my e mail and wired phone

Adam My speeds are good today at 1.9 down as good as it gets and stable as far as I know

Re: Internet failing

adamwalker — Tue, 31 Jan 2023 15:59:14 GMT

I'm glad things are fine so far. Do shout up if any other problems show up though and I'll take another look at this for you.

Re: Internet failing

stathe — Tue, 31 Jan 2023 17:04:19 GMT

When I speak of the little fan I refer to the small top right on phone and pad. The tiny cross is within it when it seems no longer linked to Plusnet but internet still connected Then I switch router off and after a minute or so on and all is well. The tiny cross has disappeared and my connection restored I dont want you to alter my settings or it will be unacceptably slow As it is I can do my bank ,e mails , iplayer whats ap and Skype which is all I want
