EX7000 - Internet drops on iOS devices on newer firmware

[VS228]

On any firmware newer than V1.0.0.68_1.0.128, the internet inexplicably drops on iOS devices. The same network does not have any issues on Android smartphones/Windows laptops. I just tried the latest firmware V1.0.1.90_1.0.156 to check if the problem had been sorted out, but, unfortunately, it had not. With the newer firmware, internet connectivity is restored only after a reboot of the range extender.

After the update, have you tried factory resetting and reinstalling? 

Are you installing using wps or using the installation assistant?
