Hi. Hope you may be able to help. I have a dell xps desktop I use at home, more as an entertainment Hun to stream to Apple TV from iTunes. The trouble I have is that the Ethernet connection keeps dropping out and only a reboot will fix this. I get the little yellow exclamation mark over the Internet symbol. I connect via a power line from a new Asus router as I now only run my virgin super hub 2 in modem mode as this was forever failing as a router. It always re established internet after a reboot but never any other way. Have you got any ideas? Many thanks.
