Wireless networking issue - signal strength

    I've just been installing a wireless network for a friend and have run into
    an unexpected problem. The set-up is as follows: A new Dell desktop with an
    Ethernet cable link to a Belkin 7360 wireless ADSL router, and a new Dell
    laptop with a USR/3com 802.11g wireless card.

    It all installed smoothly, and while the two machines are in the same room
    they perform well, go online happily and generally do everything that I
    expected of them. However, the desktop and router are in a small
    shed-converted-into-an-office in the garden, and the walk to the front room
    is no more than 10-15 metres, but once there the signal strength drops to
    less than 50% and within a few seconds I lose the signal completely.

    The blurb implies that this is way below expectations. Is this generally
    acceptable, or am I doing something wrong? I've checked the troubleshooting
    guides for both wireless devices and they seem to be set up exactly as they
    should, the two diddy aerials on the router are both vertical and it's
    positioned right in front of the door, so it's got as good a chance of
    getting a signal to the house as possible.

    Any ideas?

    What type of walls does your house have brick, stone?
    1.Ensure that you have the latest drivers/firmware, I have had a similar
    problem in the past.
    2.Give as much considerstion as possible to a "clear line of sight"
    3. A mirror or sheet of foil can, dependent on positioning of course, act as
    a reflector and give a great boost to to any link.

    Are there switchable channels on the units ? I'd try a different channel ..

    If you haven't already tried this, switch to another rf channel. There
    might just be something else in the neighborhood which is emitting an
    interfering signal right on the channel you are presently using.

    I encountered this problem in the small office building we're in. I
    installed a little wireless network and left it at its default rf channel.

    We had crummy operation until I switched it to use another rf channel,
    after which everything became good as gold.

    Good Luck,

    Jeff

    Look at some of these free, easy DIY gizmos:
    http://www.freeantennas.com/

    If you're not opposed to spending a little money, get a directional
    antenna for at least the router. http://www.fab-corp.com/ should have
    something, just make sure you get the right kind of connector. 12-15dbi
    gain would probably be more than enough.
