I'm starting to wonder if my problems have more to do with the machines
around my computers than the antenna's and routers I'm trying to use.
DEpending on the day I may have as many as all three connections or just 1,
but always a different one and even then a constant connection is rare. I'm
currently using outdoor omni and unidirectional Hawking antennas.
