Hello, while i am trying to join speaker a wifi .. i can contect to its wifi iface, select wifi network to join etc... but once i click on Join network ... the pink is still flashing ... and speaker apparently doesnt join wifi network. any idea what kind of issue it could be? I somehow luckily got connected via ETh.... is it possible that some components are faulty and thats what causing such problems with networking or just speaker comes with Retarded firmware? thanks

@sunnyjim @pukiima hi, what my a7 does is - a slight buzzing when switched on, then there is a fast red led flashing. B&W said it can be power board failure or main board failure, but they dont sell spares anymore. Any idea what issue it can be and if it can be fixed? thanks!
