We have had problems similar to this where the radio performance (ie 
signal) would degrade to very low levels, even under 30mW.  We seem to 
have solved this problem by using a 24VDC supply.  We suspect that the 
long run of ethernet cable (maybe around 150 feet) was causing this.  We 
have damaged 3 200mW radios in this manner.  However they would still 
function, only very attenuated signal.  How long is your ethernet?
