Wifi goes out a lot but comes back if I turn the phone off/on.  5S

wifi goes out a lot but comes back if I turn the phone off/on.  5S iPhone.  Not sure what the problem is.  I've heard that changing my wifi router security to WEP works but that seems pretty lame.

Hello, SDSmith45202. 
Thank you for visiting Apple Support Communities. 
Sometimes a simple power cycle of the access point can correct the issue that you are experiencing.  However, the issue could be a little more complex.  Wi-Fi routers need adjustments to settings periodically for optimized performance with the constant progression of wireless device technology.  Below, I have included two articles.  The first article will cover basic Wi-Fi troubleshooting regarding iOS device connection.  The second article cover the recommended settings for current Wi-Fi access points.
