I am having an issue with my wifi router in my house with my two Apple devices, one is an iPhone 6 the other is an iPad Mini 2 (both with latest IOS updates). The router I am using is an ASUS RT-N66U with the latest firmware. My issue is that while on WI-FI while connected to this router I lose connectivity on a regular basis and have to switch my device to airplane mode and then back off in order to get it to connect back to Wi-Fi. This only happens with this specific WI-FI network and also only happens with these two IOS devices. My other devices and laptops don't have this issue and the W-FI connection is reliable at all times with other non IOS devices. Are there any ideas on what could be the issue here?
