Test socket :-

Just phone = no noise that my ears can detect.

Phone + modem = noise.

No, I don't know what has to be done. I'm still not getting >1M.

In your post you stated "noise on the landline" so it would have been your telephone provider to fix the issue. After clarification there is noise only when modem/router is plugged in, so the issue is more complicated.

Others will help I'm sure.

Sounds like a faulty filter.

Get in the test socket and do the following:

1)Try in the test socket with a different filter.
Noise still present?

2) Try in the test socket using different phone if possible.
It's cheaper than being billed by BT if it turns out your phones faulty & causing the issues
Noise still present?

3) In the test socket.
Plug a filter into the test socket, plug the router into here. Then plug another filter into the phone side. Plug the landline in. Plenty of devices need double filtering.
Noise still present?

4) Ideally it would be good to try with another router just to be double double sure.

Let us know.

If it's still noisy in all of these then you need to get BT out and you cannot be charged as it's not a fault at your end. If you are billed you can testify it.

1) Have tried several filters.
2) modem in test socket, no phone, still 1M.
3) Will try but 2 tends to rule out my phone.
4) Had similar problems with Orange Live Box for years. They sent replacements - no difference.

A couple of years ago a BT engineer came to my home but couldn't detect noise. He said equipment at the exchange needed resetting, but also stated there could be an intermittent fault on the line. I have had crossed lines at times (people's voices coming over my conversations and strange bleeps). Rural broadband is poor in our area. Still 1M tonignt.

I stand corrected, I now have just 0.5M download speed.

Have it in the test socket then BT cannot say it's your internal setup causing issues.
You need to get the engineer out though given what you've said.

They only charge if there is no fault found or if the fault is internally
The following would be chargeable

1) Router not in the master socket, plugged into a bedroom extension socket. Engineer arrives, plugs in at master and it works. That's a fault inside your property. Chargeable.

2) You are not using filters properly - again fault inside property and chargeable

3) You are using a 30m extension cable from the master to the router. Engineer arrives and identifies this is the problem. Chargeable

4) You have a faulty Sky box or landline which is pumping interference down the line and is causing the Broadband issues.

There's a few more but you get the drift.
Essentially a fault found before the TEST socket is BT's bill. This includes the wiring to the master socket and all of the wiring outside.
If the fault is beyond the test socket - it's a fault inside your property and is chargable.

If you are in the master TEST socket you have disconnected the internal wiring. This means that the fault must be coming from BTs end provided that 1) Your phone isn't faulty 2) Your router isn't faulty 3) You are using the ISP supplied short cables.

All in all get BT out.

I had very similar problems on our phone about 1992 BB(Before Broadband etc)

Initially BT reckoned everything was OK until I managed to record some of it, one Friday afternoon, whilst talking to the Faults Desk, where the girl was deafened by the noise.

It consisted of-
General noise, frequently deafeningly loud
Crossed connections on incoming calls - simultaneously to other lines
Wrong connections on incoming calls - relatives trying to phone us and well-acquainted with our number
Engineering Test Tones

I was already in contact with senior BT staff about the on-going problems (several months), as ours was a high-priority "Red Card" line (Police Stations, GPs etc).

On hearing the recording and getting confirmation from the stricken Faults staff, the BT Manager arranged an almost immediate transfer from the "Cross Bar system", to the other, "System X", in the exchange, also involving a change of number.

The change-over happened on the Tuesday morning.

A message was left on our Answering Machine, that the transfer had taken place; BUT the New Number was not given.

My lady-wife phoned BT; BUT THE BT STAFF WOULD NOT GIVE HER THE NEW NUMBER!!

(Before CLI, 1707 etc).

Eventually, at her suggestion, the BT staff agreed to phone the New Line and give the New Number to whom-so-ever answered!

Two days later, out of curiosity, I phoned the old, discontinued, number, getting an answer from an obviously irate person, who was "fed up", getting all those nuisance calls; and it had been going on for months!


And BT had initially said that there was "NO FAULT".


=========================

I appreciate that your being on a Rural Exchange, there may not be such a "convenient" solution.

Our phone and broadband is now under EE so I guess it's up to them to fix it. I have done all checks as suggested. Thanks everyone for info. Still only 0.5M.

I've changed the Brightbox over to my old Livebox and there isn't any difference:

ADSL firmware version : A2pBT009c1.d17d
Connection mode : ADSL2
Type : Fast
Noise margin (dB) : 31.6
Attenuation (dB) : 37.0
Attainable download rate (kbps) : 5420
ADSL status : Connected [0]

Downstream Upstream
Rate (kbps) 462 1055

Are these noise levels acceptable?

EE phoned but said it will cost £140 if fault is inside my property. Just ruling out possibilities. The above is without my phone connected and Livebox in master socket.

There are significant differences! The Livebox is running with ADSL2 not ADSL2+ and is running even slower.

Even so, your line should be running at about 10 Meg. Looks like Orange is capping you to 1 Meg.
