FTTC - using an older PPPoE router

    This has probably been asked many times, but I can't seem to find a
    definitive answer - perhaps someone here knows?

    As I understand it, FTTC terminates on a BTW supplied Huawei VSDL modem.
    This modem is 'dumb' to all intents and purposes. To make it work on a
    network it will require a device - like an all in one home gateway/router
    (or PC/MAC) - that has a PPPoE client for authentication.

    We have multiple public IP addresses from our provider so deploy a basic
    edge ADSL router/modem set up using NO NAT. It is not providing anything
    other than basic L3 routing for our little block, and it feeds a number
    of internal firewalls, routers and hosts. To make FTTC 'fit' for us, we
    simply need to change our current basic edge router/modem to something
    near identical but with an Ethernet WAN instead of ADSL.

    Looking at various postings and forums it seems that there are only a few
    'routers' on the market that target FTTC VSDL. We don't want to shell out
    on anything expensive that offers a pile of features we don't need for
    the job (Draytek), but at the same time the Netgear WNR1000 is almost
    definitely a no for us.

    Needing only basic facilities I wondered if there would be any problem
    using an old Linksys router designed for cable as long as it could
    support PPPoE OK? I suspect if there are any issues it would be speed
    related and this is where my understanding lets me down. PPPoE on a wan
    port - being PPP over Ethernet (with no ATM as it's not an ADSL router)
    should be in the order of either 10mbps or 100mbps anyway?

    Is it possible to find out
    (a) if this is correct
    (b) the actual speed of such a device can support
    (c) if the device will support this at all?

    We don't need to upgrade, our speed and throughput are OK for our needs,
    but it would make some improvement without a doubt. For what we pay now
    upgrading to our providers FTTC package will cost us just over £2 per
    month. However, there is a fee of nearly £50 for the installation before
    we consider the hardware change costs - the only variable in the cost. So
    finding a lower cost basic router/gateway would not only help us, it may
    help other people googling for a similar answer.

    I note the Linksys WRT310N offered speeds of '300mbps' for CABLE services
    - but had wireless which we really don't need. Surely someone makes
    something simple and cheap to do this job!

  2. This looks simple and cheap! http://www.ebuyer.com/product/232676

    I haven't tried it, but the spec looks ok and you can't beat the price!

    Thanks Tony, but I'll pass on that :) Had issues with Edimax products
    before - but agree the price is attractive :)

    I have an old Linksys in the loft that may do the job yet. I can't see
    any technical reason for it not to work unless I'm missing something
    glaringly obvious - something entirely possible!

    Just following up on my own post here. Someone has been kind enough to
    run through the interface on Youtube: http://www.youtube.com/watch?

    Supports PPPoE, supports NO NAT. For £15 it may just be worth a gamble.

    I only know what was done by Rutland Telecom. They supplied a VDSL modem
    with an Ethernet interface.

    I connected it to the WAN port of an Ethernet router (actually Draytek). It
    does not require any PPPoE username/password.

    I can't comment as to whether other suppliers who use BT Openreach to
    install the service require a PPPoE client - but your (proposed) ISP should
    be able to tell you.

    The issue AIUI is that a router has to process each IP packet in order
    to determine where to send it, so the speed of throughput is related to
    how quickly the processor can do that rather than the nominal line speed
    of the port.

    The following web site might help:


    If you have the time, a thorough reading of the "smallnetbuilder" web
    site will offer a lot of information which I have found very useful in
    the past.

    The only thing I would criticise that for is that it's not Gigabit
    Ethernet (1000Mb/s), only Fast Ethernet (100Mb/s). While this may not
    be an issue for internet traffic going through the router, it will
    become more of an issue with LAN-side traffic as new PCs now come with
    Gigabit Ethernet LAN ports almost as standard.

    Hear what you say, but it would not be an issue as our gigabit stuff is
    kept on other switches. Only WAN stuff would forward to this device.

    Thanks - I'll take a read through that.

    The provider have pretty much said any half decent router that allows a
    PPP login to be supplied, can have NAT disabled and allows a static ip
    AND NETMASK to be entered should be fine. I'll give this little £15 unit
    a go, with my old Linksys cable modem on 'standby'.

    Thanks for the input - kindly received.

  10. So, use a gigabit switch.

  11. dunno for sure but I do know that my draytek 2910 that had served me
    well severly cramped the FTC throughput only allowing a max of around 25
    mbps downstream even all firewalling etc turned off and even though WAN
    connection was supposed to be 100mbps.

    Upgraded to vigor2920 and things started flying at 38mbps although now
    VPN traffic won't pass even though VPN is connecting..

    Ho hum. if it's not one thing it's something else...

    This is all beyond my experience, but I've found Broadband Buyer to be
    knowledgeable and helpul (and, as it's only 14 miles away, I can cycle down
    there to pick up bits):
