Try this
I've been having weird issues lately. My battery doesn't seem to work properly (losing 1% ever 2 minutes of use), wifi is a hit or miss, and my cellular signal is significantly worse than my 4S. It gets less bars in the same places.
Tonight I connect to wifi, and decided to run a long video on youtube. The ENTIRE TIME connected to wifi. I get a txt message saying I used 1gb of data in ONE day!!! (from verizon)
I checked my usage just 2 hours prior and was at 270mb. Now over 1gb. Something is terrible wrong, why would LTE be used if I was of wifi?!!?! I am getting charged for this! The only time I did anything data intensive was watching the youtube video WHILE connected to wifi.
Do I have a lemon? Does anyone notice odd reception, worse than usual battery life, wifi I believe is software, but now its using my data on my cell plan while connected to wifi (showing the wifi icon in the status bar). I reset the phone 2 times today. I did a full restore (not from backup) after noticing significantly worse battery than my iPhone 4S that was a year old. 😡

I am now at 1.7gb while my iphone is just sitting on the home screen...... 😕
I had the same problems, but now working correctly. Try this....
I had problems of sometimes slow wifi and wifi disconnected and tried all the posted possible solutions with no luck. My iphone 5 wifi is now working perfectly and this is what I did.
- I remained on WEP security, but WPA2 worked fine also.
- Changed my channel from 9 to 7, this gave me a speed increase.
- Disable the N side of my router, G only. Another speed increase.
- QoS settings, disabled WMM.
Also selected a static IP address with a DNS of
24.222.0.94, 24.222.0.95
If you restored from an older iphone ensure both devices are not using the same static IP address, this happened to me and it created connection problems.
These setting gave me an increase in wifi speed but not the random disconnects.
This fixed my random disconnects and been working perfectly ever since.
- backup iphone in itunes.
- Download the IOS 6 firmware for the iphone 5 from here

Then click shift-restore (might be update) and select the firmware which will reinstall IOS 6 and erase all content and reset your iphone to factory.
restore your backup and then go into iphone settings>General>Reset and select Reset Network Setting. Once rebooted, Setting> Wi-Fi and select your wifi and enter security string. Then change to static and ensure the IP address isn't used by another wifi device connected to your home wifi network. I found using DNS of 8.8.8.8, 8.8.4.4 gave me speed problems.
This did the trick for me and solved all my wifi problems. Good luck!!
