Hi Bob,<br>
<br>
I have found some 2 amp supplies are not what they say they are!<br>

Hi Jan. Its a 2A supply so should be fine. I've tried knocking WiFi and Bluetooth on the head but no luck so far.<br>

Hi Bob,<br>
<br>
I had a similar problem which was gone with a more powerfully power supply.<br>
