Michael says the time has come to let go of his Apple Airport and update to a new router. Leo says new mesh technologies do a better job and Apple hasn't kept the Airport design up to date. But Michael uses Time Machine to back up his Mac. Do any of the mesh systems offer USB support? Leo suggests going with Network Attached Storage or NAS and backup that way. That will work with any router. Leo prefers Synology, and you'll also need to buy the hard drives to put into them. A good two drive model would work great, and it supports Time Machine. It also backs up to the cloud.
