When Wi fi and both blutooth on and im listing to music or in a call wifi slows like **bleep**.and even after blue tooth of wi-fi disconects every few mins.only solution is to make my router toa open netawork,if i use wpa/wpa2 disconect continues.even in open netwrk mode wifi slows....Had same problem on ZR .returned it and still awaiting refund.I thought sony might have improved on new z1c.My mistake.Z has the same problem.WTH sony?
