Here is one where its worked for a minute or two, gone off again since.
It seems to work for a few seconds then go off for 5 minutes, All with the light staying blue.
what type of master socket do you have
have you tried connecting hub to test socket with a filter to eliminate problems with the master socket?
if you have type 7 have you made sure it is firmly clipped in place as that has been a problem with others
I have number 7. I have reconnected all cables, no change.
so have you now connected to the test socket with a filter to see if that helps by eliminating the master faceplate?
