More than one ADSL modem connected - No dial tone

We are trying to set up ADSL Internet at home, and have several
Speedtouch modems, with a view to connecting seperate PCs to them in
each room. Instead of trailing wires all over the house, we wanted to
conect each PC through an ADSL modem to the available phone jack in
each room.

If we conect one PC with a splitter to a phone line, all is well.

If we conect any of the other modems to any of the other phone jacks,
we get a "no dial tone" error message on the first PC.

Is what we're trying to achieve possible, or do we need a more
sophisticated solution?

Can't be done. You can only have one ADSL modem connected to your ISP at any
one time. (Unless you have multiple incoming ADSL lines.)

Assuming your modem has only a single ethernet output you have three choices.

1) Get a router and hard wire the other PC's
2) Get a wireless router and connect the others wirelessly. Walls etc.
permitting.
3) Get a router and use ethernet over power line

You can buy gadgets that plug into a 12amp outlet that have an ethernet
connection on them. Not sure if you can use multiple ones though. Someone else
will be along to straighten that out :-)

What ever you do you will need some sort of router to allow multiple
connections and to share the single IP address that your ISP dishes out to the
connection.

Yes, you can use multiple HomePlugs, e.g. to connect several PCs
simultaneously to a single router.

If there are several PCs in one remote room, it might be cheaper to use
one HomePlug plus an Ethernet switch in that room. See the diagram at

I did try something similar, but using a Speedtouch Modem and an Intel
Modem, before I took the jump and went wireless.

The problem I found was the Speedtouch would work regardless of if the Intel
was plugged into another extension or not, but that the Intel would only
work if the Speedtouch was NOT plugged in. In the end I gave up and went
wireless, except for the first desk top PC which is ethernet off the router.

Dave and others,

Thanks for your speedy responses.

Can I utilise the phone line infrastructure in my house at all for
networking PCs to a single ADSL modem somehow?

Is the only way to proceed a router / hub, and a LOT of cable (wireless
is out of the question) ?

Not really - There are almost certainly not enough spare pairs or twists in the
cable. You need proper CAT5 or better. You can do the opposite though - run
phone over CAT5.

Go for the ethernet over power. Then you only need CAT5 from the router to the
power plug and in the other room(s) from the power plug to the PC. Or, as Tony
said, if there is more than one PC in a room put a hub in and cable from that.
CAT5 from Powerpoint->hub->PCs

No, as has been mentioned, using the mains (assuming both ends are on the
same phase, which is quite likely unless you have a big factory with lots
of heavy power machinery!) is another option. There's a range of speeds,
from 14 Mbps to 85 Mbps and most recently 200 Mbps, but since ADSL is at
the low end (up to 8 Mbps) even the 14 Mbps devices will provide enough
speed for linking a second/third PC to the router.

I've helped friends (one switched from having a second phone line in a
bedroom "home office" setup, to just using the main 'home' phone number
for ADSL, and used powerline adaptors to link the upstairs room to their
dining room, where they have the master socket, and now their router and
an adaptor) using 2 units in one house (PC to router) and 3 in another,
to connect the "office" (router) to two different bedrooms.

I've not tried the router from Solwise which has the connection built-in
but it would probably be one solution you could consider, in place of
lots of cable... (Though I've something like 200 m of solid core RJ45
cable that could be used, and the boxes and faceplates for making tidy
ends, if you decided cable was more affordable... it's perhaps 25 quid
for 100 m by the time delivery is added on)

See http://www.solwise.co.uk/net-powerline.htm eg Billion 7560A

and http://www.solwise.co.uk/adsl-around-the-home.htm

You only need higher speed units (like the SAR, or 200 Mbps connections)
if you plan to do lots of PC to PC file transfers and feel the 14 Mbps
kit will be too slow. Please note that you might see speeds reported
at 5 to 10 Mbps between units... They're *not* meant to be plugged
into multi-way sockets, but they may work (at one of the homes, their
mains sockets were so close to the floor that the adaptors would not go
into the wall sockets, and had to be plugged into 4-way or 6-way sockets)

You can't do that. You can connect only one modem to one line. No
workaround.

Get a router and live with teh cables, or get a wirless router and go
wireless.

There are phoneline networking solutions but they're not certified in
the UK and are apparently rubbish.

You could try powerline networking.

BT broadband supplied 2 wire IG 1800 routers which had HPNA phoneline
networking built into them as standard, so I wouldn't say that there
weren't any certified for use in the UK. I wouldn't say they were
rubbish either, depends on how rubbish your internal wiring is.

> You could try powerline networking.

Probably the easiest way for the OP to go given the easy availability
of hardware to do it.
