I recently moved my broadband from Virginmedia to Sky and tried to reconnect my Marantz all-in-one streaming device. I couldn't get it to connect wirelessly and ethernet is less than ideal, because of the location of the two devices, so I tried a pair of Powerline connectors.

 

As the Marantz connected, there was a loud (and I mean deafenting) buzz in the speakers which was unaffected by turning down the volume on the Marantz.

 

Any idea what may have caused this?

Hi@Grahamfff,

May I know what is the model of your devices: How to find the model number of your TP-Link device 

Is the network on the powerline devices still working? 

 

There are various factors might affect the performance of a powerline products, such as AC units, surge protectors, washers and dryers and so on. All these devices may generate a high amount of electrical noise and create an unstable voltage in your home powerline environment.
In this kind of powerline environment, PLC products may encounter performance issues like poor transfer rate, or intermittent devices.

If you happen to encounter network or service issues when using your powerline adpater, please try the following solutions:
1. Install your powerline products as far as possible from appliances as you can, especially those high-power electrical appliances like AC units, refrigerators or washing machines.
2. Power off your high-power electrical appliances one at a time, to find out which one is causing the performance issues in your powerline network. Once found this device will either need to be turned off or filtered using a surge protector.
3. Avoid using surge protectors or extension plates for your powerline products. These devices should be plugged directly into the outlet.

4. Change a different wall socket to power on the device.
5. Hard reset the powerline device and repair it. For powerline extenders, please press and hold the Reset button for 10 seconds to reset them. For power adapters, press and hold the Pair button for 15 seconds until all LEDs turn on momentarily.
