Router drops broadband

My broadband drops when I use the phone.
This started 3 weeks ago after working perfectly for years. Line checks
were done by both BT and my bb provider. All ok. So I bought a new phone
and it worked perfectly up to today when it's started again.
Once again BT and my ISP have done tests, all ok.

It's the simplest arrangement; one master phone socket, one router
Ethernet cable + phone through a filter. And yes, I tried the spare filter.

Any ideas how to cure this?

I ask because somehow it sounds like a hardware problem to me.

I haven't had DSL for a while. It was not dependable in my case, as
might be true for you as well :-), but I still have the filters. There
are two kinds. One has only a socket for the phone, and the other has a
socket for the phone and a second socket for the DSL modem. It seems
that the modem had to be plugged into the phone line through that socket
to work right.

When I had DSL I had a problem like that.

I finally figured out it was the line from the telephone jack in the
house, to the box outside.

A wire was damaged in the wall, either when it was put in, or a mouse
chewed on it.

Fortunately there was a spare wire in the telephone cable, and I swapped
it with the bad one.

I would check the connections in the telephone jack at the desk, and at
the box outside.

If that doesn't solve the problem, and you have a cell phone, you can
swap to Consumer Cellular, and use this:

That is if you live in the US.

I've had ADSL problems, which I fixed by running a new phone
wire from the demarc in the basement, upstairs. (Put a new
hole through the floor, in a corner of the closet, to make
running the cable up there a bit easier.) The problem was
actually corrosion on the RJ11 telephone box along the baseboards,
but using a new box and cable, was my way of ensuring it
wouldn't happen again. You could see corrosion on the
contacts in the RJ11 box.

*******

I've also had ADSL drop out, due to a noisy ATX power supply.
I have an Antec supply, that was sending switching noise
back into the AC outlet. I could also see a "herring bone"
pattern on a TV set, proving the TV could also "feel"
the interference on the AC input. Replacing the ATX supply
fixed that.

What was interesting about the ATX supply problem, is
the problem would only manifest at around 9PM in the
evening. The modem would drop sync, and sit in a loop
connecting and dropping again. The ATX supply wouldn't
know what time of day it was, but telephone line conditions
vary through the day, and may have (somehow) played a part.

Without the herring bone interference pattern on my
old analog TV set, I might never have put "2+2" together.
That helped verify the symptoms a bit. I was also getting
a bit of a "hissing" sound from the supply, but that alone
didn't convince me to change it out.

*******

The telephone company reserves the right, to rewire the
telephone distribution system. I've had the phone company
change lines on me, without consultation. I go outside
the house, and some yoyo has a ladder up against the
telephone pole, and has just disconnected my ADSL connection
(modem drops, and I correlate that with ladder noises outside).
They change lines, presumably to give the "reseller" customers
poorer line quality than the Bell customers :-) That
particular set of operations, seemed to be part of
Bell HD deployment, and at one point, they set up a
table next to the concentrator box, and spent around
three days doing line tests for their "$100 a month"
customers. The table had an umbrella over the top of
it, so the techs wouldn't get so much glare from
the sun on their LCD screen. My outage only
lasted for around half an hour, as my line
wouldn't be getting any tests by them.

BT (British Telecom) have tested the line several times and they pass it
as green. And I must admit that the phone works superbly well, is as
clear as a bell, and only a few weeks out of the box.

My ISP (EE, formerly Orange) have also run tests; connected through to
my PC (ie up through the line, through the filter to the router) and
pass it as ok.

And now at 11-45pm it all seems to be working fine, just as it worked
fine for 2+ weeks.

I can't get BT workmen out if they say the line's ok; and similarly with
my ISP, who pass the line and the router as ok.

I have a strong inclination to just unplug the phone, which gets for
more spam calls than good ones; and use my mobile. :-)
Second idea is switch ISP to BT; which will get me a new router-modem
and filters, and also make them liable for the bb as well as the phone.

I'll wait a bit and see what the coming days bring.

You mention the phone line and modem but not if you use a router
between. How old is the DSL modem?

How old is the router? What brand? Is it separate of the modem or do
you have a combo router+modem unit? If the router is separate and when
the problem reappears, see what happens when you take the router out of
circuit and have the computer directly connected to the modem.

Yes, we need to use the filters here, and it's the first thing to check if
there's interference between the phone and the DSL signal. Every connection
to the line needs to go through a correctly operating filter.


The ISP sent me two filters years ago. One has stayed as spare, so I
tried that, but same problem.

How does one test a filter? Or where buy a new one?

Yes. Check that every single device (everything that's plugged into a phone
socket on the wall) goes via a microfilter. Check also that the router is
plugged into the RJ45 (square, non-BT) socket of a filter, not into an
RJ45-to-BT adaptor which then goes into a T piece alongside a phone.

One thing to look out for is where the connection to the router is via a
long extension lead. You'll have a filter at the router end of the cable, no
doubt, but check that there *isn't* also a filter at the other end of the
cable when it plugs into a wall socket (ie BT plug on cable going into BT
socket of filter which then goes into BT wall socket).

The principle should be: the router should have a clear path right to the
phone line that goes to the exchange (the RJ45 socket in a microfilter is
unfiltered) whereas everything else (phones, Sky boxes, help-alarms for the
elderly, burglar alarms etc) should go via a filter (the BT socket on a
microfilter).

If it helps, draw yourself a diagram of the phone system in your house with
filters, phones, router marked and see if you break any rules anywhere. It's
easy to do so unwittingly! Maybe even unplug everything except the router,
then plug back one phone at a time and see at what stage you re-introduce
the fault.

Not sure how you'd test one, Ed, but they're quite cheap. It might even be
that your ISP would send you some free. If not, they're quite cheap from
Amazon or anywhere like that. However, if you tried the second one that had
never been used, the chances are that it's OK and that it's not the
problem.


This is a list of the hardware involved;

1. Ethernet cable from PC to router-modem.
2. Router-modem.
3. Cable from router-modem to filter.
4. Cable from wired phone to filter.
5. Filter plugged into sole phone socket in the house.
6. Wiring from phone socket to junction box near front door.
7. Wiring from junction box to external box under house eaves.
8. Junction box itself.

What I'd like to do is test and eliminate items. But I don't have any
methodology for doing that.

It reminds me of an intermittent car problem I once had. All the
electrics suddenly died; everything. I took it to a garage, and they
checked and greased all the battery connections. Fine for weeks until it
suddenly happened again.
One night I was revving the engine while under the bonnet and I saw
sparks leaping around the coil. After replacing that it never happened
again.

Back to my computer problem. The best I can come up with is item 7
above. The wiring has been frequently moved about, painted over and left
out in all weather. So that's my primary target. I would have expected
BT to come and replace that, but they say the line is ok. I may
eventually have it done from my own pocket.

Ed


P.S. No sign of the problem today, and I've had several phone calls and
made a couple.
P.P.S.I once mixed vodka with orange, and drank it. Then I did it again
because I liked it. It continued in that vane for a bit. Next day's
hangover nearly took me away from this planet.

This is the sort of question that comes up in uk.telecom.broadband
quite often. What does your modem connection stats look like? This is
the sort of problem that changing to BT doesn't help. You need a
determined ISP and ones that do get their teeth into these sort of
problems are AAISP and Zen.

Did you pick the phone up at 16:14:44? I think this sort of thing can
be caused by bad connections behaving live a diode or something, they
can tell you properly on uk.telecom.broadband. You have to try the test
socket under the front cover of the master socket, plug your filter,
phone and modem in there. I doubt if it will make any difference but
ISPs aren't keen to get BT out unless that's been done.

I would have said the filter was faulty but you have tried a different
one and I don't suppose you have, or can borrow, a different modem.

You asked about filters earlier, I got mine from Solwise
http://www.solwise.co.uk/adsl_splitters.htm. I had the NTE5 faceplate
splitter 'ADSL-NTEFACE' although BT replaced it with theirs when they
came to replace the drop cable after it lost an argument with a tree.


BT say that OpenReach are in charge of the line, and they have a
call-out fee of £130, payable if they come and find no fault.
Now then, BT have passed the line as ok, so what will OR say when they
come and look at it?
They'll say it's already been passed as ok. £130!

I'm waiting on my ISP; the manager.

Did you pick the phone up at 16:14:44? I think this sort of thing can
be caused by bad connections behaving live a diode or something, they
can tell you properly on uk.telecom.broadband. You have to try the test
socket under the front cover of the master socket, plug your filter,
phone and modem in there. I doubt if it will make any difference but
ISPs aren't keen to get BT out unless that's been done.

I would have said the filter was faulty but you have tried a different
one and I don't suppose you have, or can borrow, a different modem.

You asked about filters earlier, I got mine from Solwise
http://www.solwise.co.uk/adsl_splitters.htm. I had the NTE5 faceplate
splitter 'ADSL-NTEFACE' although BT replaced it with theirs when they
came to replace the drop cable after it lost an argument with a tree.

My broadband drops when I use the phone.
This started 3 weeks ago after working perfectly for years. Line
checks
were done by both BT and my bb provider. All ok. So I bought a new
phone
and it worked perfectly up to today when it's started again.
Once again BT and my ISP have done tests, all ok.

It's the simplest arrangement; one master phone socket, one router
Ethernet cable + phone through a filter. And yes, I tried the spare
filter.

Any ideas how to cure this?

Did your providers check the equipment itself?

I ask because somehow it sounds like a hardware problem to me.

I haven't had DSL for a while. It was not dependable in my case, as
might be true for you as well :-), but I still have the filters. There
are two kinds. One has only a socket for the phone, and the other has a
socket for the phone and a second socket for the DSL modem. It seems
that the modem had to be plugged into the phone line through that
socket
to work right.

Johnny's post reminded me that you're in the UK.

Now I wonder if there is a difference in the way it's done across the
pond that invalidates what I said above.

Sorry if so.

Yes, we need to use the filters here, and it's the first thing to
check if
there's interference between the phone and the DSL signal. Every
connection
to the line needs to go through a correctly operating filter.


The ISP sent me two filters years ago. One has stayed as spare, so I
tried that, but same problem.

How does one test a filter? Or where buy a new one?

Ed


That's half the battle, is verifying the POTS phone works correctly.
If you acquire dial tone immediately on your analog phone,
that's done by DC line state change. That helps prove the line
is still well connected from a DC perspective. If the line is
free of audible noise in the voice band, that helps prove there
isn't a bad connection or an impulse noise source (spark gap)
close by. So if the analog phone is pristine, the line is
likely good. (It could still be a problem within the CO,
at the termination point. It could also be a higher frequency
problem, such as my noisy ATX switching power supply.)
