rick, the very first thing you want to do is to replace your battery. Then re-evaluate your WiFi. Make sure that you set your date and time correctly. Then try these steps first:
1. On the iPhone, turn the Airplane Mode on
2. Go to General > Reset > Reset Network Settings
3. Restart the iPhone
If that does not work, it is possible that this is caused by a failed WiFi IC. you could try a reflow and see if that will work for you. Greyed out wifi is not caused by the antenna, but a defective WiFi chip. Hope this helps, good luck.

+== Update ==
+With the new information provided by you, if a good reflow has failed, you may have to replace the WiFi IC.
