I've recently bought a D-Link DIR-300 wireless router. While disconnecting its power supply from it, I got a tingling sensation when I touched the plug (to be clear, I'm talking about the 5V DC plug, not the mains plug). An AVO meter shows about 90V AC to earth from either side of the 5V plug. Short circuit current to earth is about 0.1mA. Still, I thought these things were meant to be completely isolated. Has there been a change of approach? Sylvia.
