I have four TL-PA717 (AV1000) devices. Sorry the model number is not availble to select from the pick list
Three of them pair easy using the pair button. The 4th will not pair however hard I try. I have also tried to pair using the tpPLC app but on entering the key the device is not found. It is plugged into the same mains socket that I used to set up the other devices, so this cannot be the problem. The green power light just flashes at me.
Any suggestions please. I think it is faulty.
