iPhone 6S Plus Wifi won't stay connected
I noticed yesterday that my iPhone 6S Plus wasn't connected to the Wifi at my home. My Wifi is on an Apple Airport Time Capsule with Version 7.7.3. My iPhone is running iOS 9.0.2. I tried resetting the network settings on the iPhone yesterday but it's still having this issue. Wifi is turned on, and when I go into the Wifi settings it shows my network, but it just doesn't automatically connect. If I tap on the network name, it does connect again until it goes to sleep. When it wakes up, it won't automatically reconnect. Any suggestions?
Thanks for any help you can give me with this.
