Connecting a *cable* router to an AOL *cable* modem (NTL cable)

Discussion in 'Home Networking' started by Martin Underwood, Jan 2, 2007.

  1. A friend has an AOL Broadband 200 cable modem which is connected to her PC
    by Ethernet. She wants to add a wireless router - obviously a cable router
    rather than an ADSL router. I presume the AOL software is already configured
    to talk over the PC's Ethernet port, so that won't need to be re-configured
    because it will still be talking over Ethernet - except via the router.

    Is it a case of just turning off the modem (removing its power), plugging it
    into the input (WAN) port of the router instead of the PC, and then powering
    it back on? I know some cable modems will only talk to the MAC address that
    thay have already been talking to in the past, and to no other. Does
    powering the router off and on force it to re-detect the MAC address of the
    device that it will talk to, or is anything else needed.

    Once the router is talking to the modem, I'll then need to configure the
    wireless side of things: SSID, channel, encryption, WPA key, for the second
    PC (laptop) that she'll be connecting wirelessly.

    Maybe. :)

    You may find that the AOL setup assumes nothing between the PC and the modem
    and the PC does some of the work - ie it will have the account and login
    details. Now *some* makes of router will have an install routine that gets this
    out of the PC, including the MAC address, and inserts it into the router
    because now the *router* needs to do the authentication. Of course if the modem
    is doing all this then you are right, just changing the cabling ought to work.
    Otherwise you are going to have to de-install anything AOL put on the PC and
    set up the router to connect. You might need to de-install some of the AOL
    stuff anyway. In addition you will also need to turn NAT on in order to allow
    more than one PC to share the connection. If you can't get the router to clone
    the MAC address then turning everything off and on again and going through the
    original NTL setup should get it to recognise the new MAC - If memory serves
    NTL will hold four MAC's - Only using one at a time of course and needing a
    power cycle to change.

    Ah yes. I've just downloaded the user manual for the Netgear WPN824, which
    is the router I was recommending my friend to buy. This router allows you to
    define the MAC address that the router presents to the modem (you can set
    the router to clone the address of the PC that the modem used to be
    connected to!) and to supply username/password. There's even an "ISP"
    drop-down which lists "AOL Cable" amongst others. Sounds fairly
    straightforward. Famous last words. I presume that if a username is
    required, it will be an AOL screen name (maybe with "@aol.com" tacked on the
    end) and corresponding password.

    Yes, I knew about enabling NAT on the router, as for an ADSL router.

    Let's hope it all works: I live about 200 miles away so I'll be guiding her
    over the phone. Should be interesting!

    Reconfiguring the AOL software will be amusing, if it is currently set to
    talk specifically to the modem (as opposed to being set to use any available
    LAN port). So much easier to do when you can see the screen yourself rather
    than doing it over the phone. NOw what did I do when I reconfigured AOL (for
    someone else) to talk to an ADSL router after it previously had been setup
    to talk to an ADSL modem? Should be a similar process.

    Don't delve too deep.
    It is not difficult. I took advantage of a friend needing hers set up to try
    it out, the conventional way and using AOL setup/
    As I replied on prior threads on this subject it is a breeze to set an ADSL
    router up on AOL.
    AOL user name and password is all that is needed. no need for cloning MAC
    address or anything like that.
    Once up and ruunning you can then use with or without the AOL front end.

    But the OP said it was NTL/cable with an AOL modem so it *will* need the
    details and have to jump through hoops for the MAC as I said.

    Oops, Thanks for that Dave
    I saw no mention of NTL in his main post body. Only after you said I noticed
    it was in his subject line which passed me by.
    I wonder how long it will be before NTL Cable do away with registered MAC
    addresss as Telewest Cable have for some time?
    Cheers

    NTL have never required MAC addresses to be registered in areas using
    stand-alone cable modems. Four or five years ago the way DHCP leases were
    given changed: they went from a fixed four hours to a scheme where the lease
    length increased upon renewal until it reached 24 hours. Prior to that
    change, you had to wait until the DHCP lease expired (ie up to four hours)
    before you could attach something with a different MAC address to the cable
    modem.

    I heard last night that my friend had managed to get everything working
    without needing my help. I didn't get chance to find out the details - like
    whether she needed to clone the PC's MAC into the router to make the modem
    think it was still talking to the same device, or whether she needed to
    configure the AOL screen name and password into the router - because it was
    in passing during a trivia game we were playing that she sent me a private
    message to say "aren't I clever - I've managed to set it up all on my own".

    I was well impressed!

    Ah I did not know that NTL treated STBs and cable modems differently. My
    comments were WRT STBs and were correct as of two years ago, when I threw them
    out, - and the DHCP lease thing did not apply either.

  10. Thanks for that snippet. I was always under the impression that they used a
    registered MAC as per the old Telewest way that was. Now we know.
