I recently bought an iPhone 5 and almost right away I noticed a problem. I wouldn't stay connected to the home Wi-Fi. After a few minutes of not using the phone, it would drop the Wi-Fi and go back to LTE. I'd have to notice this before using up all my data and re-enter the password. Any idea what the problem could be and how to fix it? Thanks!
P.S. I haven't tried connecting to other Wi-Fi hot spots besides my home.
