I currently get music drops in AirPlay, which I blame on slightly weird architecture and a million wifi networks all on the same channel (I've tried changing channels, but in London that's kinda a fools errand). My current setup is a crappy router with a new time capsule connecting to that and setting up a second network, with an airport express joining that network. I'm thinking of upgrading to a new Mac mini (I realise they're not great, but I'm moving from a 2007 iMac, so it will be a big difference!), which has ac wireless. Would it therefore be a better idea to connect the airport express to the time capsule by wifi and turn off any wireless stuff on the express? Because then it's a clean ac network with no n components screwing things up. Or will that make no difference at all? Sorry if this is a bit rambly, I'm probably not expressing myself very well. edit: I should probably make clear that I know n devices attached to an ac network don't slow anything down, it's just that keeping the AirPlay on a strictly ac band would remove interference due to stronger radios.
