Play 5 Will only now connect with Ethernet. Used to connect wirelessly. Have 1 other Play 5 +, 2 play 1s, 1 connect amp & 1 boost all of which are connecting wirelessly except for the boost which is connected by Ethernet. Have tried turning all off including router and rebooting but failed to connect wirelessly. Tried resetting to factory but will not connect wirelessly. Tried connecting with Ethernet cable which works but looses connection as soon as cable is disconnected. Tried connecting adjacent to router but will not connect wirelessly. This speaker has worked well for 18 months until now. Can anyone advise if this is a problem with the Play 5.
