Does anyone else use an Asus router behind a Sky hub to access a VPN? I have an ASUS router connected to my Sky SR102 hub so that I can connect my Sonos bridge to the USA via a VPN and listen to Pandora. But it is dropping out quite often, seemingly at random. I wondered if there was a way to make the connection more robust. But my internet is ISDN and about 5Mbps. I'm actually chuffed that it works at all since the Sky Hub does not have a modem-mode unlike my previous Virgin SuperHub!
