15, sometimes 16. DirecTV receiver & slave, Roku, Amazon FireTV Stick, 3 laptops, a personal server, 2 Android tablets, an iPhone, an Android smartphone, a kindle e-reader, a VOIP box, a networked printer, sometimes another work laptop. This is only a list of items that have been connected to my home router within the past 7 days, so these items are all currently in use. Approx. 3 years ago, I had 4 devices: 2 phones, 2 laptops.
