Unit is @1 year old, have a few annoying issues 1) After it goes into sleep mode, I cannot wake it unless I quickly press the power button - a quick tap will wake it. Bluetooth keyboard and mouse says "connection lost" - but it comes back after waking. Assume the loss of connection is why I cannot wake by moving the mouse or pressing akeyboard button? 2) At various times I lose internet connectivity. Have to reboot. I have my work PC hardwired to my router (same as my iMac). My Windows PC can still get to the internet when the iMac cannot. I likely do have intermittent connectivity loss as at time, my work VPN connection breaks / re-establishes itself. But why would the iMac be dead in the water until a reboot? I do have a new Surfboard router coming next week - maybe that will help?? any thoughts?
