Wi-Fi issues on iPhone 6 after downloading iOS 8.1?

After updating my phone, it's struggling to identify my router. I've done the reset network settings and still the same thing keeps re-occurring. Is this happening to anyone else and what are the solutions as I don't wanna use up data

  • Will downloading IOS 9 delete the storage that iOS 8 took up? I have a 16gb iPhone 6, and it come with iOS 8, and I only had 11.6 gb to work with as soon as I got the phone with all of the software installed. My question is: will downloading iOS 9 delete the iOS 8 data, thus freeing up more space after the download because iOS 8 took up more storage?

  • IPhone 4 FaceTime connections issues after iOS 6? Why? Any It is pretty upsetting that I've had so many issues with it in the last couple of days considering some of my friends can't talk on the telephone so our main means of communication is through FaceTime and it is constantly reconnecting… What can I do? I had NO issues WHATSOEVER until iOS 6. I'm thoroughly disappointed with this.ugh. I did find something on apple's website of others having the same issue.
