Apr 17, 2014 3:20 PM in response to clopoby JAH1294,Hi
Lots of people have seem to have had the same issue with ios7 bugs you can try these quick fixes but i believe most people have ended up contacting apple in the end.
Try switching Airplane mode on for 30 seconds or so, then turn it off and try connecting to Wi-Fi again.
Try holding down the Home button and the Sleep/Wake button until your device restarts.
Turn your router off for 30 seconds and then switch it on again.
Go to Settings > General > Reset > Reset Network Settings and then set up your Wi-Fi network again from scratch.(Note this will reset all your bluetooth setting too such as paired devices)
Try changing the channel on your router and check the rest of the settings.
Make sure that your router firmware is up to date.
Hope this helps

Oct 4, 2014 3:26 PM in response to clopoby jacobfreakingharris,The only way to fix grayed out wifi is to go in ifile and change the wifi property list file. Go to var_preferences_SystemConfiguration and find the wifi plist. Open it up with the plist viewer and turn AllowEnable on. I hope I have saved you from a trip to the apple store.
