Its nice to see you on the answers forum, I am sorry to see that you are having a problem with the Ipad and the 350 not connecting. What version of the slingplayer app are you using? I know that there was an update that was just released for the Ipad. You should try to install this update and try to connect a few times and see if that solved the issue. If it does not could I please have you post what IOS you are using and what version of the slingplayer you are using.
Hope this helps,
