I currently have an Apple Airport Time Capsule - the newer shape supporting 802.11ac. This has served me perfectly well since 2013! Ive just purchased a larger house and would like to extend the wireless network. I notice the Airport Express is still available, but this does not support 802.11ac - considering by iPhone/Macs etc all support 802.11ac, I would like to continue to use this protocol. What are my options, other then purchasing an expensive Airport Extreme to extend the network?
