    Hello all - bear with me please coz I'm a total novice at networking as
    you'll appreciate the more you read my post {:0)

    We've just had our exchange reach it's trigger level so I'm starting to look
    into what I'm gonna need to get both my PC's connected to ADSL.
    My heads banging trying to get to grips with all the different hardware names
    and differences between them.
    Basically what all I want to do is

    1)Be able to get dsl on two machines (obviously I suppose!)

    2)Not have to have my main PC (downstairs next to the phone line) - switched
    on all the time for the other to access the net

    3)Download files from my digital camera from one PC to the other - (whichever
    happens to be on at the time will be used to get the images from my camera to
    PC)

    I want to use a wireless network as the two PC's are on opposite sides of the
    house and would be a pain in getting the cable from the main one to the one
    upstairs. As I'm getting everything new, I will be getting the new 54g type
    (especially considering the fact I'll be transferring pics which will be
    128mb+ in total). Am I right in saying that I'll need :-

    An adsl modem/router combo downstairs by my main PC
    A short length of networking cable and NIC card to connect to it
    A PCI/USB wireless adapter in the upstairs PC to connect to the router
    downstairs?

    If so, I would really appreciate some advice for good, reasonably priced
    hardware to do the job, and from where...... plus, any sites with nice and
    simple explanations, diagrams etc to help me get my head round the set ups
    etc would be a great help
    Many thanks - told you I was a novice ;-)

    No, you need another end for the wireless network.
    If that is part of or connected to the modem/router/switch then you'll
    be able to use the upstairs PC while the downstairs one is off but it'll
    be quite expensive,
    Despite the falling cost of wireless, it's still cheaper to run cables,
    but you may not want to in your house.
    I suspect it will actually be cheaper to connect to a wireless
    modem/router by wireless from downstairs too, unless you already have an
    ethernet card or motherboard socket in the PC. More versatile anyway.

    There's a big speed difference between a PCI (100Mb/s) and a USB (2Mb/s)
    ethernet (10 or 100Mb/s) or wireless (18Mb/s) connection, but you won't
    notice it when surfing the net because your "BT broadband" ADSL will be
    only 0.5Mb/s at very best, say at 02:00 am. If you can get broadband
    cable (NTL or Telewest), you'll get 0.6Mb/s most of the time..
    Those speeds will only affect playing games between the PCs and
    (slightly if your impatient) transferring files.

    Hope that helps

    wireless (18Mb/s) connection...

    Whilst I agree in principle with the point you made, I don't
    understand the figures you're quoting here. Care to clarify?

    Well, sorry, the 2Mb/s was a typo for 12Mb/s

    This would fit the "specified" speed of USB-1 but I wouldn't quote the
    specified 460Mb/s of USB2 because I've read reviews of USB2 100baseT
    adapters that couldn't reach 50Mb/s and I think it's fair to say that no
    USB1 10baseT adapter is as fast as a PCI 10baseT adapter despite 12Mb/s
    being apparently faster than 10Mb/s. This is down to duplex problems and
    I think 6Mb/s is a better figure for USB1

    I see from another post of yours that you recommend USB wireless
    adapters to get the aerial away from the PC - do you find them as fast
    as PCI or PCMCIA wireless NICs ?

    My 18Mb/s wireless figure was a wild guess at an average. I know they're
    claiming 54Mb/s now, but do you think that's realistic?

    As for 100baseT, nobody has seen a tenfold increase in speed. Maybe 8x
    for over 1000 clients on a local superserver database or 5x for home
    gamers, but only 5% or so for shared internet access, even with 2Mb/s
    broadband.

    My point is, unless your home network is to be used for internal gaming
    (as many are, though) you needn't worry about these speeds at all.

    I don't think dedicated gamers (I am not) would choose a USB2 link
    (460?) over 100baseT (PCI of course) - or am I wrong?

    Fine, understand now.
    Yes, but that's based on gut feel not measurement. The flying lead
    is my get-out-of-jail card for an awkward customer site - much
    easier than persuading the customer he really wants to relocate his
    PC, or needs to by a separate antenna.
    Haven't done any measurements, but all of the benchmarks I read
    suggest 18-24Mbps is realistic.
    Correct, the bottlenecks in the NIC/PC/software/disk drive etc of
    the endpoints govern the benefit you'll gain. But 10 vs 100Mbps is
    also about allowing more nodes to share the same LAN infrastructure
    without delaying each other.
    I'm told that with heavy usage, a USB connection would take a few %
    more of the cpu power - no gamer would accept that!

    Either way the key issue for network gamers is not data throughput
    - games don't generally chuck huge wads of data around - but
    latency, aka ping time.
