Poor ADSL connection

barnettgs — Thu, 14 May 2020 12:58:20 GMT

Hello, I have two ADSL connections which I have been using for some years now.

A few weeks ago, I noticed that one of the connection was being very slow and it is like that to this day. At first, I thought it was due to busy network due to Coronavirus. However, it was gradually getting a bit worse so today, I decided to have a look at modem statistics, it turned out that 2nd line has very poor connection, is half the speed of what it should be. Also upload speed is poor.

Have a look below and you can see the difference. Both ADSL sockets are sitting next to each other and nothing has been changed.

who is your ISP for both lines

have you checked for noise on the slower line?

Both lines are BT.

Unfortunately, I'm profoundly deaf!

Also both modems are connected to master sockets and no telephones or anything connected at all, just ADSL lines. What else it could be?

By the way, you can see noise margin is 'normal' at 6.0 dB on ADSL 2. If it was noisy, SNR margin would it be high?

But line attenuation seems off, it should be same as ADSL 1.

ADDED: Forgot to mention that I swapped over ADSL modem a couple of weeks ago, thinking the old modem might have gone badly but it's still the same.

Is it possible to get someone just to check k the phone line because it does look like a line problem with speed halved and increased attenuation

No 2 lines are the same but don't expect such difference

can you enter your phone number and post results remember delete number

Of course, no two lines are the same but they always have been similar in the past few years but not this half.

You are currently on adslmax and may benefit if you upgraded to adsl2

your attenuation on 'good' line is 56db but on 'poor' line it is 63.5db and may be higher as that is maximum router will show. Hence why you need some way or other to get both your lines checked for line noise but I think poor line does have a line problem

Hmm, line 2 speed is used to sync at around 4 Mbps until recently - similar to line 1. I see that my minimum guaranteed speed for both lines is 1 Mbps so a test above showed it was below that guaranteed speed.

I do rather to get line 2 get looked at first, however when it get sorted out, does ADSL 2 increases upload speed to 1,024 - if so, that would be a big increase from a pitiful 448 kbps! 😄

Upgrading to adsl2 would increase up speed to roughly 0.8/1mb. It may give slight increase in down speed but line needs to be checked for noise first as adsl2 is more aggressive on any line noise

All right, any small increase would be great.

Would be great to have both lines upgraded to ADSL 2 once the lines are checked over.

Post back after checking lines for noise

dial 17070 option 2 should be silent and best with corded phone preferably from test socket

Since you rely on someone who is hearing - unfortunately no one is hearing in my house, apart from little kids.

I have decided to use BT's own online troubleshooter and submitted it.

Post back after you get connection fixed. Even young children could tell if the line is silent or if there is any noise apart from the announcement - crackle, hiss etc

Re: Poor ADSL connection

No problem, will report back.

Re: Poor ADSL connection

Happy to report that the line has been fixed a few days ago and the speed returned to where it was. Got around 3.25 Mbps on speed test which is normal.

Could I request ADSL 2 for both lines and see how it goes?

imjolly — Thu, 21 May 2020 13:27:32 GMT

great line fixed and speed back to what it was

I have asked mods to see if they can help get both lines upgraded to adsl2 mods will post here
