WAP54G signal strength and speed problem if more than 5 feet away

    Two of my Intel Centrino laptops with WinXP on them can't keep a steady
    connection if AP is more than about 5 feet away. My Intel 3.06Gz
    hyperthreaded laptop, however, doesn't seem to suffer other than the
    speed goes from excellent to very good.

    Could Centrino chipset have anything to do with weak reception?
    Or could it be the AP?
    Are there any rules of thumb for AP placement for best coverage?

    The laptops and the AP are pretty much new (I've had the AP for several
    months now).

    I would really appreciate any help with this one.

    Thank you.

  2. That's wrong. Any particular model laptop and wireless card in the
    laptop? It's kinda difficult to offer suggestions with no clue as to
    what your tinkering with. All Centrino laptops and wireless cards are
    not identical.
    That would be a fair indication that your WAP54G access point or
    wireless router is working.
    The chips are usually fine. However, the drivers have a big effect on
    Centrino operation. Dive into the Intel web pile and excavate the
    latest drivers for your unspecified Centrino laptop wireless card. It
    is also possible to misconfigure the wireless settings. There were
    also some nasty compatibility issues between Netgear (and other)
    access points and Centrino chipsets. There were firmware updates for
    the access points and wireless routers that fixed this about 2 years
    ago. I don't think the WAP54G was affected but you might wanna check
    for the lastest firmware.

    I suggest you drag the Centrino laptops to a different access point or
    wireless hot spot (coffee shop) to verify that they are the problem.
    No. If it works with the unspecified model 3GHz Intel laptop, it's
    probably not your WAP54G.
    Yes. Unobstructed line of sight between the access point antenna and
    your laptop is best. You can usually go through one or two walls
    without too much difficulty. Three or more walls is a crap shoot.
    Aluminum foil in the walls won't work at all. Don't bury the antenna
    and you should get at least 100ft of range to a typical laptop.
