Hi, I know there's a LOT of articles about that but I've not found yet an article that answers all my questions about the setup I want at home. 1- Can Airport Express extend my existing "NON-APPLE" wifi network ? If I want to obtain the best WIFI performance, I need to connect my airport express to an Ethernet cable ? What configuration on the airport express should I use ? 2- Can I use the airport express as an airplay destination at the same time it's extending my network ? Thanks !
