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.
Bob
