you can take the stock one I posted above and save it to a build.prop file, then you can connect your phone with usb debugging enabled and through a command prompt type adb push build.prop /system/build.prop

that will give you back the stock build prop on your phone.

of you could copy the build prop above and paste it over the current one you have, you will need to save and reboot after that and your wifi should be back if it was just a build prop issue.
