Is apple doing something about the "NO" wifi on IOS 7...???

Difficult to offer advice when you don't state the problem in detail, but perhaps this will help:

Otherwise you'll need to give us specifics about your setup and the problem.

Wi-Fi works perfectly fine for myself and millions of others running iOS7 on multiple models of iPhones.

There isn't a problem with io7 and wifi, but some have experianced a wifi failure after updating and blaming io7. Some speculate that the update caused the phone to heat up to a point to cause the wifi chip to fail. I have the problem with the wifi and it didn't happen till after a couple of months after I updated to os7. I don't blame it on os7 i blame it on a crappy wifi chip. I wish apple would own up to that. Its obvious that there is a large number of bad iphones with wifi failure that deserves a warranty extension in my opinion. They've done it for lesser issues.
