802.11 at 2.4GHz should not interfere with
the 310MHz rf from the remotes. The CM15A is
not noted for good RF range.
www.access10.com has a modification to add
an external antenna which obviously voids
the warrenty.
A number of users have diagnosed computer
power supply noise as a cause for the CM15A
not working reliably. This is a PLC problem
and not an RF problem. Try rotating the
antenna on the CM15A to the "up" position
and don't plug CM15A into same outlet strip
as the computer, unless just downloading new
file.
