Another Playbase user with WiFi problems

Hello,

My playbase has been unable to connect to wifi for well over a year now, so effectively I’ve had to connect it directly to my router which means it is not controllable via the app or useful for anything other than the permanent connection to the TV. I can no longer connect it to the network to use it for Spotify or other services. I’ve gone through all the troubleshooting procedures but have never been able to reconnect the system wirelessly.

I notice from this forum that this is not an unusual problem. What options are available to me at this point?
