Hello I have just bought a second handed powerline AV500 kit.

It works very good, I have just few questions. 

- Led powerline blink no-constantly; Wifi led always blink fast. Is this the correct signaling for V1.0??

- The wifi device use to became quite hot. Is located in a big room. Is this normal?

- The wifi device issues a very very slight whistle. You can ear it If you are very close to the device. Is it ok?

Thanks
