Those of you experiencing hiccups during play with the Node2 and using the WiFi connectivity, I strongly recommend to keep it as far away as you can from your TV or any other device that uses a remote control, preamp, integrated amp, or even your (external) DAC if it has remote control volume adjuster. In my experience, the remote control devices (can) interfere with the WiFi signal going into the Node2. Just as an experiment, point your device remote control to the front of the Node2 and lower/increase the volume and watch the blue light and watch and see if it flickers. For me, its 100% repeatable and every time I lower the volume on my TV the light flickers the signal gets lost. It might depend on the type of remote control you have but its a simple experiment and you can simply rule it out or in. I discovered this by accident and I no longer have the TV on while I play music through the Node2.
