Hi,
same issue here…….i use an ipad 2 and two D-Link 815 Router (Surface and mixrack).
Every 20-30 minutes after connect the mixpad app with the mixrack or surface router I get an message called: “The Wifi connectivity has been restored” and you only can click the “ok” button…..often this message is show 3 or 4 times.
After this happend the connection between the mixrack or surface router is lost and i have to restart the mixpad app and try a new connection.
Then it works fine……for the next 20-30 minutes.
The mixpad app does not show any warning message of the lost connection.
I have tried many things to solved this problem:
Use only 2,4 GHz or 5 GHz, using different wifi modes, enable or disable multicast, DHCP or static ip, show SSID or hide SSID, close all other apps on the ipad, shut down……..but nothing works.
And yes…..I am not happy.
Regards
Juergen
