What connection method did you use? I am not sure which bug you are referring to as we have not yet been able to recreate the specific issues. This topic contains various solutions to different problems, including a shairtunes2 bug fix that you might be referring to.
For now, please try using WPS, Access Point Autostart or following the normal Wifi procedure.
If you are having issues with the latter, please share your steps and error messages so we can understand what might be the problem.
Firstly, do make sure your ethernet cable is reomved after you configure your WiFi and reboot, if you are going with the normal WiFi configuration.
