NTL cable modem and Belkin router

A customer has bought a Belkin router which she wants to add to her existing
NTL cable modem so as to share the connection between two PCs.

In view of sections in the Belkin manual, I'm slightly puzzled as to what is
needed to make the two work together.

The modem is labelled "ntl:home 120, 60194E-A12" and the Belkin router is
labelled " N10117 / F5D5231-4 / Ver 1100".

The modem has Ethernet output to the PC and the router has Ethernet input
(on the WAN side) and four Ethernet outputs (on the LAN side).

Is it as simple as connecting the router's WAN socket to the modem's output
by non-crossover patch cable and then connecting the computers by patch
cables to the router's LAN sockets? I would have thought so, but there are
statements in the router's manual about configuring broadband username and
password for PPPoE. Does this suggest that the router's WAN port sends the
usename and password to the modem so the modem can authenticate with
broadband, possibility mimicking something that the PC does at present when
directly connected to the modem?

Unfortunately I didn't have time to try a simple connect-and-go approach
when I visited the customer to investigate another problem.

I have this router, all I did was connect the WAN port to my cable modem
(ntl 250) and the PC to one of the 4 Ethernet ports on the router, then just
switched everything on and it all worked fine, obviously you then log into
the router and configure the firewall, and port forwarding etc bit that's
all I had to do.

Yup all straight forward as Leigh said
I use Belkin +Blueyonder modem
NB all cat5 connection cables are straight Through

I'm not familiar with the specific models, but I am familiar with the
principles.

I have a similar box (from a different supplier) which has those
things plus wireless. I'll use it as an analogy to answer your
questions.

Yes, that's the idea. Are there some LEDs which will show whether you
have been successful at this level? Until that's working, nothing
else much is going to be any use.

Once the PC has a working Ethernet to the LAN side of the router and
(if you're using the default settings) has got itself assigned an
address on the private network via DHCP from the router (this address
might be 192.168.x.y for some values of x and y), then it should be
possible to open a web browser and talk to the router at 192.168.x.1
(same x as before. googling seems to suggest that your box will
default to x=2).

AFAIK you don't need that for the kind of NTL cable connection which
presents an Ethernet interface.

Mine has a pulldown for connection type, which can be
[ DHCP Client or Fixed IP ]
[ PPPoE ]
[ PPTP ]

When you're looking at the router management web pages with a web
browser, there probably will be some kind of Help menu that might tell
you a bit more about what the router expects.

My hunch is that you're looking for the first of these options, in
which case the PPPoE user name and password are irrelevant.

There's something in the help information about setting a MAC address
if instructed by the provider. Maybe someone who's on NTL will tell
you about that part.

Yes.

PPPoE is an ADSL thing.

I have precisely the same setup, but with a router model number F5D5230-4,
which must be an earlier version of the same router. Paraphrasing the
(excellent) instruction book, the stages are:

1. obtain ISP and network info (MAC address, IP address, host name and network
settings. There's a space in the manual to write them down.
2. Power down everything and connect computers to router. Connect WAN port to
modem.
3. Turn on modem. Connect power to router. Check routers WAN Link light is on.
4. Turn on each computer and when they have booted up check the LAN Link
lights are on.
5. Set up TCP/IP and file sharing on each computer (long discourse omitted).
You can use the Belkin CD for this or do it by hand.
6. Configure router for internet connection (set ISPs to "never dial a
connection", "use proxy server" etc. (explanation omitted).
7. Access the router (the IP address of mine is 192.168.2.1). You can then
select dynamic or static IP address and clone the MAC address.
8. Enjoy.

If you need it, there's a reset button on the back of the router.

I've probably given you much more than you need. As a beginner I found the
Belkin manual and set-up software excellent.

For NTL you no longer need to clone the MAC address.

In this case I think all you'll need to do is turn everything off,
'plumb' it together (output from CM to WAN port & attatch the computer
to one of the LAN ports), turn on CM & wait for it to link, turn on
router & let it synch & then turn on the PC, no worrying about PPOE etc.

Once it's connected together & working then you can play with some of
the settings but it should be as simple as what I stated..

Nearly. You will need to power everything off, then power on the
modem, wait around 30 seconds, then power on the router, wait another
30 secs, then power on a PC. The router should get an IP addy from
ntl, your pc from the router. If you don't power on in the right order
nothing will happen, as ntl won't recognise the router and give it an
address.

Only relevant if the WAN port is for an ADSL connection. You are
/sure/ the router's WAN port is ethernet?

not required for ntl - they allow at least 3 CPEs with different MACs
at any one installation (though not simultaneously of course, thats
why you need a router).
