In my experience, the Playmaker has always been a bit 'flaky' when connected wirelessly.  Dropouts and its disappearance from Airplay devices were frequent when I used mine wirelessly.  If you search the older forums you will see many similar experiences. The simplest solution is for a wired network connection - this has solved many glitches for other users.  If cabling direct to your internet modem/router is difficult, consider using powerline network adaptor such as these:

Thanks Guy for the reply. I will have to try that as its too far to connect it to the router. Otherwise it works really well and is quite useful.    

Strange.  I suppose that you could try hard-wiring the TV instead but you'd possibly need a powerline adaptor for that. Alternatively, have a look at this old thread and maybe investigate some of the options including setting a static IP:

So I purchased a powered network adaptor. The adaptor has full bar signal.....connected the playmaker via Ethernet cable. It works initially then a couple of hours later when the TV has been used it has the same problem. As soon as the TV is switched on I can't connect anymore to the playmaker via Airplay. I can see the playmaker on Apple Music but it says cannot connect. If I turn the TV off the playmaker still doesn't work, I have to reboot the playmaker each time.  I have tried to change the channel used on the Wifi router but it made no difference.
