Over the past several weeks since bringing this up again, we've had varying degrees of success with wifi linking for remote control. There have been a few jobs that we linked up on the first try, and it worked without issue the entire gig. Other times, the most common issue is that we establish the link fine and after a few songs, we notice that the link has disappeared, and when we try to re-establish it, he (the other guy) does not see my iPad to request the link. He then has to go into manual mode, for scrolling of the lyrics. Then, in a few times, the link has reappeared after 15-20 minutes. It is simply unreliable. I was wondering if any other users are having success with wifi linking, and if so, please share the router setup.
