    I read a link in this NNTP forum that mention all the crossover cable
    can cause damaged machines. Why? Is this a non-regulated technology by
    stardars? Somebody know?

  2. Crossover cables do not damage machines. If someone says
    that they do then they are spreading myths.

  3. Don't believe everything that you read, josepe, especially on the
    Internet.

    I'm not saying that it's impossible, but I've never seen any reports
    of damage from crossover cables, and they've worked fine every time
    that I've used them over the past several years.

    There might be some network cards that don't get a reliable network
    connection using a crossover cable, because the cards need the
    constant link that a hub or switch provides. I haven't run into that,
    either.

  4. I don't know that they'll damage anything but I do know that some network
    cards won't work with a crossover cable, they need a standard cable and a
    hub, switch or router.

    Show us the link and maybe we can understand. I've never seen a
    crossover cable cause damage.

  7. Where does that link say that crossover cables can damage your equipment?

    What it does say is that many manufacturers will void your warranty if you
    tell them you are using a crossover cable. It also states that crossover
    cables do not always work and can be problematic.

    I've never heard of a manufacturer caring. I've never had problems with
    them, either, but I've read seemingly credible accounts of them not
    working with certain cards.

  9. Cross-over cables were designed strictly for connecting one hub to another.

    Linksys has this to say about them:

    http://kb.linksys.com/cgi-bin/om_is...ev.nfo&record={2BC}&softpage=IKW_ENU_JDocView

    "Linksys does not support networking with the use of crossover cables, as
    the connection between machines has been proven to be unstable and
    unreliable. Industry standards support networking with the use of an
    intermediary device such as a hub or a switch. Linksys adheres to such
    industry standards for networking."

    There are similar statements on numerous other manufacturers web-sites. I
    chose Linksys because they seem to be the most popular in the consumer
    market.

    That's still a long way from saying they damage equipment or void
    warranties.

  11. I agree! ... Which, I believe was my point if you read earlier in this
    thread. :)

    Of course, Linksys doesn't sell crossover cables, but they do sell hubs,
    switches, and router.

    I can't imagine any way in which a network card would know (let alone
    care) whether the 8 wires coming to its connector come from a
    straight-through cable or a crossed-over cable. The "stuff" at the
    other end of the cable all has to meet the same specs, right?

    Just a thought ...

  13. Yeah, I thought that too until it didn't work. On some equipment it works
    fine, on other equipment it works sporadically and on other equipment it
    doesn't work at all.

    Right..... the crossover cable don't cause damaged "per se" (I was
    reading too fast).
    But the article mention some warranty are invalid with this issue. Some
    of you says the connection is non-stable... umm I think no more use
    crossover on my jobs. The use of switch-to-switch is near with real
    objetive of the crossove.
    ...sorry erroneous words.
