IPHONE 5 NEVER STAYS CONNECTED TO WIFI NETWORK ( MY HOME OR WORK WIRELESS)

Hello there DanielHarryRobinson,

I was researching the issue you are describing here, and found an article named iOS: Troubleshooting Wi-Fi networks and connections found here http://support.apple.com/kb/ts1398.

Basic troubleshooting

• Tap Settings > Wi-Fi and turn Wi-Fi off and then on again.
• Verify that you are in range of your Wi-Fi router or base station.
• Confirm that your Wi-Fi router and Cable/DSL modem are connected to power and turned on.
• Check whether other devices (portable computers, for example) are able to connect to the Wi-Fi network and access the Internet.
• Update your Wi-Fi router to the latest firmware.

  For AirPort Base Stations, refer to this article for information about firmware updates. For third-party Wi-Fi routers, check the manufacturer's website for details on updating your firmware.

• Restart your iOS device

  Hold the On/Off button until "slide to power off" appears. Slide to power off your device. When it is off, press the On/Off button to turn it back on.

If that doesnt quite cut the mustard I recommend the section at the bottom the article

If you're unable to join a nearby Wi-Fi network

• Try restarting your Wi-Fi router by turning it off and then on again.

  Note: If your ISP also provides cable or phone service, check with them before attempting this step to avoid interruption of service.

• When joining an 802.11n Wi-Fi network, ensure that your router is properly configured. See this article for more information.
• Reset network settings by tapping Settings > General > Reset > Reset Network Settings.

  Note: This will reset all network settings, including passwords, VPN, and APN settings.

And if all that doesnt work, then I recommend sections 1, 3, and 5 of our iPhone Troubleshooting Assistant found here http://www.apple.com/support/iphone/assistant/phone/which will fix the issue if it is a software problem on the iPhone.

All the very best,

Sterling
