I've got a mid-2014 rMBP, clean install to Yosemite. iPhone 6 clean install by DFU to 8.1. Asus RT-AC87U for the router. All features of continuity work well except for phone calls. I have my router's 5 GHz and 2.4 GHz bands set to the same SSID so that the devices are able to seamlessly move between them. However, phone handoff only works when both rMBP and iP6 are on the same band. I have the setting in the router that prevents devices on different bands from communicating (Set AP Isolation) disabled, so my rMBP that likes 5 GHz easily talks to the 2.4 GHz printer regularly. However, the phone call thing sucks. If anyone has the same configuration as me but fully functional phone call handoff, would you mind sharing your router settings?
