Are there better ADSL modem routers out there?

    I'm only a few yards from the BT exchange. I'm with MAAF on their 8Mb
    Max account and I'm getting a download speed in the region of 5Mb.

    What's the likelihood of increasing my download speed by a) upgrading my
    router's firmware and/or b) by getting a 'better' modem/router? If
    that's an option, who are the market leaders?

    The service is quite solid at the moment, but I use VoIP for my calls
    ( and occasionally I get drop-outs.

  2. What does your modem actually sync at? If it's syncing at 8Mb and you're
    only getting 5Mb then it's either a BT virtual-path capacity problem in
    your exchange (remember you're 50:1 anyway) or theres issues insude your
    ISP. Upgrading your modem won't help any of these, so start by looking
    at your ADSL hardware and seeing what it's giving.

    For your VOIP problem, I'd look at your uplink speed. Others may be
    able to comment on features that apply to QoS for voice. I'd
    like to hear if any exist.

    I'm of the opinion that 8Mb/sec is a walk in the park for any modern,
    properly functioning modem/router combo. It's not that fast.

    You can use XP's pathping command to show ping times and dropped
    packet counts between your PC and any host service on the net you have
    problems with. An occassional dropped packet isn't bad, but most of
    the time there should be none.

    The echo times should be examined as a source of problems for VOIP,
    but the solution is probably upstream and you have to address it via
    your ISP.

    Where are you getting this download speed from?

    What is the signal strength, SNR, downlink and uplink speed shown as?

    Modem Status

    Link Status Connected
    Us Rate (Kbps) 448
    Ds Rate (Kbps) 8128
    US Margin 25
    DS Margin 13
    Modulation MMODE
    LOS Errors 0
    DS Line Attenuation 15
    US Line Attenuation 14
    Path Mode Interleaved

    Gordon, I take it that this is exactly what you mean?

    Now go here....

    Be patient, it's crap and run the test until it gives you some data rates and
    your *profile*.

    If your profile's 7150kbps and it likely is - any speed issues aren't the ADSL
    connection at all.

    In any case 'only' 5M is very good.

    8128Kbps is the maximum line speed. You've got a very fast ADSL
    connection and a different router won't increase this speed.
    The Margin figures (aka signal to noise ratio) are good as are your
    line attenuation figures.

    Am I right in thinking your download speed of 5Mbps is from a download
    test tool?

    Given the high quality of your basic ADSL connection (8Mbps) the cause
    of your lower download speed (5Mbps) is to be found further up the
    network. Given that you're getting VoIP dropouts I suspect congestion
    further up the network.

    Unfortunately there's little you can do sort of changing to a service
    with a better than 50:1 contention ratio.

  8. I live only 70m from the local exchange and get the same 448 and 8128.
    My modem router is currently on the end of about 50 feet of very poor
    looking extension wire. I usually get 4 - 5 megs but occasionally 6.5
    I suspect local contention is the problem. Alternatively Newnet could be
    a bit overwhelmed. They have just greatly increased their prices for
    heavy users to protect their network.

    I'm with Madasafish. They provide their own 'broadband speed test' on
    their website. That's all I use.

    Try removing all phone devices other than your modem and run speed
    tests. If you see a speed improvement, put the phones back one at a
    time, test, and see if one of the phones is a problem.

    Not necessarily in answer to this question, but it may help and can be
    applied in any ADSL configuration.
    The use of good quality filters and better still "active" rather than
    filters can improve the quality of connection dramatically.
    For best results do not use a filter.
    If you need to use a filter, place the filter where the line enters the
    "Y" off at this point and use one leg for all telephony and the other line
    for all data.
    You'll only need one filter in this scenario and therefore reduce losses.

    How patient? 5 minutes, 10 minutes?

    This is my test result

    Test1 comprises of Best Effort Test: -provides background information.
    IP profile for your line is - 7150 kbps
    DSL connection rate: 448 kbps(UP-STREAM) 8128 kbps(DOWN-STREAM)
    Actual IP throughput achieved during the test was - 6019 kbps

    Looks good, then!

    Hmmmm... exactly what I tried today (three routers, two filters, and
    a few spare cables) when visiting friends whose ADSL stopped working
    on 28/12. Tech Support (on an 0845, not sure where) guy was rather
    negative when I mentioned I had tried three routers, with and without
    using filters (I had at least one cable with RJ11 to BT plug) and was
    of the opinion there should always be a filter... My guess is that
    ISPs drum it into all staff to stress this to customers.

    After that long try again in an hour. I know, it's rubbish. If you persevere
    though it will eventually give you your bras ? profile. I don't know of any
    other way to find out that info.

    That's the fastest it gets with BT's Max.

    Doesn't get much better !

    Your actual throughput will now be down to contention at the DSLAM and how good your
    ISP is.

    The "filter" removes the high frequency audio tones that carry the data
    and thus allows normal telephone usage to run simultaneously without
    the tones being heard.
    If the connection to the ADSL line does not have the need for a normal
    telephone, or the ADSL tones do not interfere (hearing loss) with the
    use of the telephone, or is only used a fax line, then the filter serves
    no purpose.

    "Tech Support" types are usually following scripts and have little or
    no technical knowledge.

    I beg to differ. If you don't filter a fax machine, ADSL won't work
