Try replacing the static IP address with nothing. The software should be smart enough to know it needs an address and request one. (DHCP) I have run into the ipad attaching to the wrong WiFi network. I named my portable WiFi NoInternetHere and of course there isn't and there is a sizable password. Make sure you're attached to the right network when you can't see the mixer. It's gotten to the place where there seems to be 3 or more WiFi's everywhere. It will always attempt to attach to any network it thinks it had seen in the past. Starbuck's WiFi all have the same name. Badly setup WiFi's frequently have the same name..... Sometimes it helps to force it to forget a network you don't want to connect to.
