    [linux] Linksys USB Wireless-N adapter Actually finds Lesser Count ofWireless Networks than my Laptop's Internal Network Card's Antenna

    My Wireless Network USB Adapter used to find the same number as my
    laptop's built-in network card. I have been running this Backtrack
    Live OS from a USB. But after my manipulation of the construct to boot
    this Backtrack OS from harddisk, my wireless USB adapter finds less
    than half the amount than before, whereas my laptop built-in wireless
    card still sees all of them.

    Now I want that linksys usb thing to behave just as my laptop built-in
    wireless card!

    I will sacrifice small mannons for help!

    Thank you,
    J

    Couple of things, n usually provides no speed or range increase over b/g,
    the only time it seems to be greater is when the salesmen mouths are moving,
    or the ad people are wriing lies......
    Second, the built in wireless card uses an antenna bult into the lid of the
    laptop, while a usb dongle has a little teeny tiny thing inside the dongle,
    or even the external usb devices have multiple/mimo/diversity/antennas,
    which can't be changed, and are usually the cheapest things the manufacturer
    can get away with, as you can see, don't work very good in most instnces

    Bottom line, there are **NO** n standards yet, so if you bought anything
    with it's snake oil charlatin claims of bigger/better/more range/faster/etc,
    you got robbed....

    Jah. Question is, why was USB-thing behavior _different_, _before_ I
    pumped that Linux OS unto the harddrive?

    Well...?

    Given the lack of information regarding the model and version of the
    Linksys device, which version of BT you used(BT3 beta?), does it use the
    same driver on the hard drive as it did from the USB, whether you still
    get all the wireless networks if you try booting BT from the USB again ,
    you would be better off asking on the appropriate BT forum.

    Hard to say, but the driver takes the signal/noise ratio, creates a cutoff
    number (n), and says display it if it is higher than n, and don't display it
    if it is less than n... the value of n probably changed with different
    drivers/os's......

    ever play with something like say netstumbler? It will show a lot of AP's,
    but many are way too weak of a signal to connect too, many of which will
    show in netstumbler, but not in the various wifi programs used by the os to
    display (since they are too weak to connect to)...... so you can see that
    the program determines what is displayed and what isn't... Sounds like the
    linux driver/program just isn't bothering to show ap's that are too weak to
    connect to.

    If you extend that signal strength/noise argument to the antennas in the lid
    of a laptop/usb dongle, that too will change the signal/noise ratio...

    To specifically answer your q, it is a different program/driver with
    linux/windows, and has different cutoff numbers (what shows/what doesn't...
    ie one may show -80 and the other may show -79)

    Are you losing the display of ap's that you use/know have a good signal, or
    just marginal ones?
