Help connecting ADSL modem to NTL cable

Discussion in 'Home Networking' started by Free Cornwall, Sep 30, 2005.

  1. Hi,

    We've just connected to NTL Broadband, and want to share the internet
    connection wirelessly around the house. However it seems the ADSL
    modem/router we've bought isn't compatible with NTL (which seems to need
    to use its own modem and comes into the house via a cable). Is there any
    way to connect the NTL modem (which has a USB and Ethernet output) to
    the Linksys router (which has a Rj11/12 line input and four Ethernet
    outputs) and have it share the connection? Any help much appreciated.
    Thanks in advance.

    Most probably not, but knowing the router model would be a help to say
    definitely.

    Huh?

    Assuming the NTL cable modem has an IP address of 192.168.0.1

    Give the Linksys Router an IP address of 192.168.0.2 Set the default
    gateway ON THE ROUTER to 192.168.0.1 and the DNS server IP address on
    the router to the same as the gateway or ISP DNS server.

    On the nmachines, they should get the IP address from the router. If
    not, set their IP addresses manually and set the DNS server IP addy to
    to 192.168.0.1 or the same as the ISP.

    I'm afraid you've both missed the part where he mentions that it's an
    ADSL Modem/Router with RJ11 'WAN' port.

    ADSL broadband devices are completely incompatible with cable broadband.
    I'm afraid the original poster is SOL, and will have to purchase a more
    suitable router.

    A good reason for not purchasing combo boxes. Although afaik there's no
    reason in principle why the LAN side of an adsl router shouldn't also
    offer an ethernet port for just this eventuality: I rather doubt they
    exist, but asked the OP on the offchance.

  6. so the router can route from LAN port to LAN port can it ??

  7. Many apologies; I incorrectly assumed by your response that you didn't
    realise that the OP's router was equipped with a sole RJ11 port for WAN
    connectivity. You know what they say about assuming - it makes an ass
    out of you and a guy called 'Ming'.

    Rhetorical question?

  9. Thanks for everyone's help. Had a feeling it would be a bit impossible.
    Have now ordered a DSL router, and Ebuyer'll give me a refund on the old
    one apparently. Thanks again.

    A DSL router is precisely what you don't want.

  11. I really hope you mean "cable router". DSL is the same technology as
    ADSL, and will be just as incompatible as your existing router.

    Something like one of these:

    <http://www.ebuyer.com/customer/products/index.html?product_uid=52897>
    <http://www.ebuyer.com/customer/products/index.html?product_uid=37452>
    <http://www.ebuyer.com/customer/products/index.html?product_uid=44088>
    <http://www.ebuyer.com/customer/products/index.html?product_uid=41592>

    I have one of the top routers (the cheapest, naturally) and have had
    zero trouble with it. Sure, it's a bit lacking in features, and I
    wouldn't trust the firewall, but it does the job.

    That really is unbelivable! ASDL IS ****NOT****
    CABLE, ASDL IS BT/KINGSTON COM. CABLE IS A TOTALLY DIFFERENT
    TECHNOLOGY!! I AM NOT MOCKING THE OP I AM MOCKING THE OTHER POSTERS WHO
    ARE TRYING TO GOVE SOLUTIONS TO USING A CABLE MODEM THEN CONNECTING IT
    TO AN ASDL ROUTER WITH BUILT IN ASDL MODEM!!! IT IS 100% IMPOSSIBLE!!


    BYE 4 NOW

    Good Luck Free Cornwall And Feel Free To Mock All the Other Posters!!!

    Actually, clueless idiot, if the cable modem has an RJ45 port, it is
    perfectly possible.

    I put it to you, Free Cornwall, that on Fri, 30 Sep 2005 16:38:39 +0100
    you did state the following;
    I have just done this for a friend who's got an NTL cable modem using
    one of these;

    Just set the pcs to dhcp and off you go. Easy.

    's ok :)

    Btw, I hope people have spotted the typo - I wrote "LAN side" instead of
    "WAN side" in my last posting. I just wish some people could remember
    to proofread before hitting send :)

  18. Sorry. Cable/DSL. Really should start thinking about what I'm doing.

  20. most things labelled "DSL routers" are the same as "cable routers" or
    "broadband routers" in that they have RJ45 WAN ports to connect to a
    DSL modem, USA style.

    "ADSL modem/routers" is perhaps the best description to use for the
    thing the OP has and doesn't want.
