    And the newer devices have "internal" antennas, no connector to even
    try a gain antenna of any kind. Just try different orientations for
    best signal strength. I do have a camera feeding another Buffalo
    ethernet adapter, 2.4 gHz only, perhaps 100 feet away from the
    router that works marginally. The router and the adapter must be
    positioned carefully but the slow data rate limits me to 3 frames
    per sec. or less. Performance is degraded where the distances cause
    weaker signals.

    Yes, the problems I cited were all through interior uninsulated
    frame walls, and this place is certainly not earthquake proof, we
    went through one hurricane and it creaked like it was coming apart.

    Thanks for your observations.
