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:
- 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:
- 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.
I hope this information helps ....
Have a great day!

Unfortunately, I also am having the same problem. A 5 year old refurbished iPod Touch has better WiFi capability than my brand new iPhone 5, as did my old iPhone 4 and my Wife and Son's iPhone 4s phones. I made the mistake of resetting my network settings and now have the same problem as the OP - cannot connect. Please don't insult my intelligence by posting basic troubleshooting problems like making sure my router is turned on. There are thousands of threads on the Internet regarding iPhone 5 WiFi problems so it is clear to me that it is a manufacturing defect. Have been a loyal Apple customer for a long time but I've had it with this. Taking it back today and replacing it with another kind of phone, which will eventually lead to my exit from the Apple ecosystem. Learn your lesson from what is happening with the new Macbook Airs - admit the problem early and fix it.
This is a common problem with iOS devices running up to the current iOS 6. Because the iOS box is a closed system, the ability. To identify the cause requires using Xcode with a laptop connected to a modified iOS device setup to debug this issue. Pretty much a non-starter.
I can tell you this much. This problem is cumulative: it occurred over time after use of the iOS device and very rarely with a freshly wiped or new device.
I have found with multiple iOS devices having this problem that the quick fix is shard restart of the iOS device (aka Windows fix). This seems to trigger some sort of clean up at boot time which alleviates the problem for a while (month?) but the problem will come back.
Very frustrating... this method of crowd sourcing quality assurance out to the customer community to perform. Imagine if your car crapped out like this or your fridge... Would you hook your laptop to your TV to help the manufacturer debug their wares or would you buy something different next time...
A hard restart is accomplished by holding the power button and the home button simultaneously until the iOS device spontaneously shuts down without the slider for shutdown. Then, when the screen is black, let go and press the power button.
