Connection drops on Nexus 7 but not Ipad

I've got a Legrand Myhome lighting system conected via an IP gateway, on the Android it drops out randomly anything from 10 - 60 seconds after going into a panel. The connection goes from flashing green to solid which I guess is a lost connection.

If I reenter the panel then it reconnects again.

On the Ipad I don't have the same problem.
