If you can't control _anything_ with your AH controller, it may have
died.  But if it's just certain devices, think about any electronic
equipment you may recently have acquired (TV, DVD player, Cell phone
charger, etc.) which has a switchmode power supply.

Many of these devices will introduce noise on the powerline or
have heavy capacitive filtering ("signal sucker") which will
attenuate the X10 signals.  To test, unplug suspected devices from
the wall - merely turning them off isn't sufficient.

If you identify an offending device, get an X10 noise filter and
plug it in between the device and the wall socket.
