ios 8.1.1 wifi problems

Everything in the house is working that isn't using the latest 8.1.1 version, I only updated my phone to 8.1.1 because I wanted to make sure it worked fine. The Wi-Fi worked great with 8.1 so restoring my iPhone or rebooting a router doesn't seem like a plausible solution, considering rebooting my iPhone every time fixes it for a day or two.

Another thing I noticed is even if I turn off Wi-Fi on my phone I still can't make a data connection only voice works.

I'm having these same problems... with 8.1 and 8.1.1 on my iPhone 6. Has apple offered any solutions?

Just the basic troubleshooting, which provides a temporary fix, if at all. I have done every reset possible, and the only thing that works for me is to turn cellular data completely off in Settings when I am connected to a wifi network. Otherwise, it drops all the time. This never happened to me on my iphone 5 with ios 7. I think ios 8 is the problem, which has still not be resolved for many people. Unfortunately, I am very close to dumping the iphone 6 and going to a Samsung galaxy. I hate to do it, but this is a terrible problem to deal with daily. Constantly changing settings is very inconvenient.

I just found out that Apple released 8.1.2 for the iPhone and doubt other devices. This addresses in bug where ringtones can come up missing. That's basically it, I heard another release is on the horizon 8.2 but that it won't be released until early next year.

Update...since I did a factory reset ("Erase All Content and Settings" under General > Reset) on my iPhone 6 with 8.1.1 a week ago, I haven't had the issue of wireless and LTE not working randomly. Fingers crossed that this is a permanent fix but, for now, it seems to have helped.
