Strange ADSL problem

x-posted to uk.telecom as well.

Went round to help a neighbour earlier who has just had BTBroadband
installed.

Broadband is working well, but something strange is afoot - he cannot
use his BT line for voice calls if his Netgear router is plugged in
(to make/receive a call he has to unplug/switch-off his router ...
which kinda defeats the object of broadband).

With the router plugged in, and taking the phone off-hook he gets
nothing .. no dial tone at all. Ringing into his BT line with the
router on gives an engaged tone (?!)...

First thing I done was change the NTE5 for a new-style openreach one,
and also removed his filters and replaced them with a ADSL faceplate
....

Still no joy - these actions haven't cured it ... and I'm stuck !

Any idea's ? What next ?

The phone is a BT Branded DECT (1 handset) ... and as I said the
router is a Netgear variant.

Cheers

Jim!

Is there another phone in the circuit with the handset off
hook? If not, try a different, basic wired, telephone:
1st: In the master-socket front, with the router connected,
2nd: Remove the router connection and try again,
3rd: Remove the faceplate and connect the phone directly in
the test socket of the master. Did any of this bring back
dial-tone?

Look for a short-circuit, or low resistance (loop) in the home
wiring, also including the router. This will be seen by the
exchange as a phone off-hook and give it dial-tone, which will
be removed after a time with no dialling. Adding to this loop
a phone being picked up as well will not allow the exchange to
see the phone going off-hook, so it won't give you dial-tone.

Hi John

Thanks for the prompt reply.

There are no other phones (or equipment) plugged in. There is 1 other
extension socket but I disconnected that.

I tried using the test socket, symptoms still the same. With the
router unplugged (and the phone plugged in) I get dial tone - but the
minute I plug the router in the dial tone just drops straight away.
Unplug the router from the socket and dial tone returns (?!?!).

It's gotta be something related to the Netgear router, or maybe even
the cables ...

Cheers

Jim!

Re: Strange ADSL problem

A firmware update for the Netgear, maybe?

Sounds like the router is faulty.

Well done Brian, wondered how long it would take someone to get to the
obviouse answer.

The router is faulty OP, you have proved it faulty so don't go any
further & take it back to where it was purchased from & demand a
replacement.

Simple really if you employ KISS & use a little logic & yes it has
been known to happen before . Do not pass go, do not call the ISP
(unless they supplied the router) & above all don't contact BT (unless
they've got £200 laying around doing nothing)...

I had this problem. I have no idea what caused it but a BT engineer
rewired it so ADSL only went through the one phone socket and the voice
line went through the other two.

Hi,


I would say the two most likely candidates are:

- faulty router
- faulty BT side wiring or configuration at the exchange

The other suggestions are probably candidates on the "more unlikely" list.

Modular swapout fault testing should be able to win the day here again.
Borrow somebody else's known good ADSL equipment, test at this premises.
Test their router at another known good ADSL line, etc., etc. You will then
be able to determine which of the above two it is (assuming it is one of
these more obvious candidates), otherwise employ similar logic to follow
through the identification of the other candidates people have suggested.


Best wishes,



News Reader

Ah! the old configure_the_circuit_so_the_subscribers_line
goes_dead_when_he_plugs_in_the_router parameter.

Always gets them that one!

I've noticed a number of posts recently about faulty
DSL modems and routers looping the line.
I wonder if they get zapped by lightening?

The problem is either the router & its leads or problems at the exch
(when ADSL connected exch equipment puts loop on line)
Plug router in, power it up, note result
Plug router in, no power, note result
Plug just the router lead in (without router), note result
Try the above on another line (does not have to be ADSL), note results

>From the above you should be able to work out if it is the router,

leads or the exch equipment.
