Using X18 Air live. Internal wireless router no good in a noisy wireless environment and so very dodgy in most venues.I use an external dual band router and connect on the 5G band.

Very solid and responsive connection although I do get very occasional dropouts; could be my Kindle Fire tablet rather than the Behringer. My drummer used a series 1 iPad Air and has not seen any dropouts, he's also using the 5G band.

Within the android app I use a custom layer to show just what is important. Can't get this to work on the iPad.

Side issue - also remote controlling an X32 for the church band I'm in using the Fire, again via 5G on an external router and this is noticeably less solid, Could be the Fire but not been able to do a comparison with a iPad yet.
