Q: I phone 5 network connection problem

I'm sorry to hear you are having issues with your Wi-Fi / password.

The information below may help you with this issue.  It includes some of the steps you've already taken, but suggests additional steps as well:

iOS: Troubleshooting Wi-Fi networks and connections

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 you are still experiencing a Wi-Fi issue after trying the above, choose the symptom below that closely matches your issue:

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.

  If you are using a Wi-Fi router at home, refer to your user manual/documentation to assist you with some of these suggestions. 

• Check the manufacturer's website for firmware or software updates for your Wi-Fi router. 
• Check the wireless security option of your Wi-Fi router: 
  • If you are using WEP security and have multiple WEP keys on your Wi-Fi router, try configuring your Wi-Fi router to use only a single WEP key in key index 1. 
  • Consider using WPA or WPA2 instead. WPA and WPA2 encryption protocols are newer, more effective security options for wireless networks than the older WEP protocol.
• Temporarily disable wireless encryption or security on the Wi-Fi router to rule out encryption issues. 
• Disable 40MHz in the 2.4GHz settings on the Wi-Fi router. Mac computers, iPhone, iPad, and iPod touch do not support this mode. Disabling it may reduce interference issues.
   
• Supported Wi-Fi networks vary by iPhone, iPad, iPod touch model (Example: Does my device support 802.11n?). Refer to Tech Specs for detailed information on which standards your device supports.
