if it is greyed out in the settings area, then you should try to disconnect from it if you can, then try turning wifi off and on again at the top of the screen.

Hello atdesiato. Sorry to hear you are still continuing to experience connectivity issues with WiFi. Have you tried resetting your network settings? Settings>General>Reset>Reset Network Connections? Once that is done, please try placing your phone in Airplane mode for about 15 seconds, then disable that option. Please keep us updated.

Just so you know, you are not going crazy. I have this same problem.
I've read into this issue and there seems to be a rare hardware issue where the WiFi, Bluetooth, and Personal Hotspot become disabled. Hard reset and updating will not fix it.
Unfortunately the only thing that can be done is get is replaced.
I know this is going to sound crazy but my iphone 4S lost bluetooth and wireless capabilities, I found a video on youtube that said to use a hairdryer and hold it on the top ear piece part of the phone until the screen shows that it's about to be overheated and needs to be shut down, immediately turn the phone off wrap in a paper towel and put in the freezer for about 10 minutes. Somehow this fixes the solder on the antennae. I laughed but it worked.
