I have purchased a sub gen 3 in the hope to connect to my playbar. The sub finds the network, connects and then drops out. I’ve rebooted my router several times but it will not hold the connection. 

I have rebooted all devices, reset an everything and reset the router. Still unable to connect. I’ve attempted from iPad, iPhone and iMac - nothing seems to be working. 
 

I am now losing the will to keep the sub as it seems to be a very expensive device which is collecting dust!

Any help would be gratefully appreciated. 
 

Thanks!
