How to figure out of Airport Express is working

    I have an Airport Express that is set up as an extender. Recently the
    Airport Utility and the indicator on the AE itself has shown as green.
    However, there are times when neither device we use with it can hook up
    to it, even from 6 feet away. Even when it is hooked up, it is often
    only a weak signal.
    Anyway to figure out what is happening?

  2. Kurt-

    You might try a third device. Unless it is located near something that
    is causing strong interference, there appears to be a two-to-one
    probability that the AirPort Express is malfunctioning. While repair
    might be possible, replacement might be less expensive.

    One thing you can try is to reset the AirPort Express to factory
    settings, and re-install it as an extender. Check the "Tips and
    Troubleshooting" chapter of your Setup Guide.

    My old second-generation model is partially reset by using a
    straightened paper clip to hold down the reset button for ten seconds.
    A complete reset is done by holding down the reset button while plugging
    it in, and waiting until the status light flashes before releasing the
    reset button.

  3. Another thing to try Fred would be one of those freeware wireless signal
    testing programs, like Vistumbler found at:

    http://www.vistumbler.net/

    or inSSIDer 3 which can be found at:
    http://www.majorgeeks.com/files/details/inssider.html

    One note about inSSIDer, they went commercial after the above freeware
    release. inSSIDer 4 is only available as a paid or demo version.

    Anyway try one or both of the above and see if someone else has setup a
    router or access point on the same or adjacent radio channel and is
    interfering with your signal.

    I'll try both. However, since the extender is around 6 feet from where
    we use the things that are having problems reaching the extender, I find
    it hard believe interference would be the problem.

  5. If someone has a wireless phone or other device like wireless headsets
    operating at the right frequency you could be standing side by side and
    a laptop or other device might not be able to sort out the two signals.

    Using either of the RF sniffing programs already mentioned you can take
    a laptop and power off your known radio stuff and see if others are on
    the same channel. Then power your stuff on and check the signal level
    on a laptop and see how "loud" the transmitter is broadcasting the SSID
    you are looking for compared to the other signals (if any). At the same
    time you can see how far away you can still get a valid signal.

    I have been in large apartment complexes where there were 5 or 6 devices
    found on practically every channel. Took a bit of tweaking to get
    things working right there. Funny thing was that some of the apartments
    had unsecured connections that were quite a bit faster than the slow DSL
    I was paying for.

    If all else fails, take the Airport and a laptop to another physical
    location and see how the signals look on the SSID checking programs.
    Reason I mention that is there are RF signals that can jam an access
    point but are not visible (understandable) by receivers. They sense the
    interference but have no idea what is actually causing it. Trying
    another location can help pinpoint if that is the problem.

    If I was installing/troubleshooting access points for a living I would
    invest in one of those wireless spectrum analyzers that check the n/g/a
    bands as those can identify interference regardless of the source
    device, but then again they don't usually come cheap...

    I'll try both. However, since the extender is around 6 feet from where
    we use the things that are having problems reaching the extender, I find
    it hard believe interference would be the problem.
