    No. Try a different channel, remembering that g uses four of them at
    a time so there are really only three choices of channel. The signal
    is likely strong enough, but some neighbor has a cordless phone or
    wi-fi interfering. If the problem is really a signal problem rather
    than an interference issue, replace the adapter or router, whichever
    isn't transmitting like it should.

    "g uses four of them at a time" HUH????

    No, it uses one. However, due to width of the channel, only three of them
    are non-interfering (1, 6 and 11 in the USA). OP may still find relief
    changing channel, even to one of the other 8.

    Also, consider a higher gain anntena(s) for the base unit. Maybe this
    "booster" could help: http://www.mobilemag.com/content/100/104/C10612/

    I remember a Linux-based spectrum analyzer program for WiFi, it was on
    a SuSE 9.1 Pro DVD I used to have. If the app is still available on a
    bootable "Live" GNU/Linux CD/DVD, this could be used to map spectrum
    useage in her vicinity--thus telling her what channels are most and
    least congested/contested. Remember, besides WiFi-G, she's competing
    with microwave ovens, vacuum cleaners, flaky TV sets, and cordless
    phones. SSMA helps reduce data corruption, and well-written software
    in the router should automatically map the vicinity for competing
    wavelength use. But well-written software isn't the rule.
    Ah, how many times have I heard the cry, "I need more power!"

    NetStumbler could also be used to get a rough idea of which channel(s) will
    work best in the particular area, and determine if there are competing WiFi
    sources nearby.
