iOS 7.0.6 wifi problems

I have had terrible problems with this update. I updated my iPhone 4s and iPad, and since the update neither of them will connect to wifi. They would connect, then drop, then reconnect, then drop, etc. I chatted with an Apple Support employee and he suggested to reset network settings. Once I did that, neither device would connect at all. Then he suggested to reset all settings. That didn't work either. Finally, he suggested a full restore on both devices. I did that - and neither of them will connect. He ended the chat before I was able to say that the restore didn't work.

I still can't connect to wifi on either device and I know it's in relation to this update because both worked perfectly fine before the 7.0.6 update. My iMac is connected to the same wifi and has had no problems, so I know it's not an internet issue. Both now say, "Failed to join network."

Has anyone else had problems?
