Is anyone having wifi problems on their iPad after downloading iOS8?

Question

My mother has downloaded iOS8 onto her iPad3 and is now unable to get wifi on it. It keeps asking her for the wireless key but when she inputs it, the wifi icon appears at the top of the screen as usual then just as quickly disappears. Has anyone else experienced this and been able to solve it?

This is great news that everyone's WiFi are having issues after an iOS update!!!
Let me explain, and I hope someone from Apple really really looks and responds to this issue effecting everyone.
I updated my iPad2 to iOS 7.1 a few months back, and then I stopped getting WiFi when I'm more than 10 yards from my router at home.  Tested in multiple WiFi networks, locations (in different countries even), and even went as far as changing the settings or shutting off any other airwave frequency devices at home (like 2.4 GHz handsfree phones, radios, tvs, PS3 wireless controllers, bluetooth signals).  I even had my iPhone4 (iOS6) and iPhone 5S (on iOS7.1.2) as comparison since they have no issues. What I found out was, my iPad2 on iOS7.1 performs weakly on 2.4 GHz signals.  5.0 GHz much better.  I don't mind replacing my old 2.4 GHz only router to one with 2.4 GHz + 5 GHz, but it won't solve the problem when I go to a network in the public (like airports where I frequent). 
I went to the Apple Store 4 separate times (in 2 countries), to let them know about the situation.  They could not do a distance test at the Apple store, because they are on the 2.4/5.0 routers. They did a diagnostic twice with the hardware, and everything checked out fine.  So they began advising me to "Reset Network Settings" and even as far as "Reset All Settings"... basically started from a blank iPad2, nothing worked because I'm sure it was a iOS7.1 issue.  I don't think they have 2 different pieces of WiFi receiver on the iPad2, and I am certain it is a software issue.  Makes me think, did they purposely change settings to weaken the receiving of the 2.4 GHz signal?  (That's just a civil lawsuit waiting to happen...)
I downloaded iOS8.0 on to my iPad2 hoping they fixed this WiFi issue that has already been a hot topic in these forums since iOS7, but of course the update failed to correct the problem.  Right now, to me, it sounds more and more like an overlook iOS programming that maybe causing this WiFi issue, since it is also happening to people who upgraded to iOS8 and iOS8.0.1 for many different type of devices (even on brand new iPhone6).  An WiFi only iPad2 that can't receive WiFi is very close to being a brick.  Is not a good feeling bringing your iPad2 to the airport to find out it won't pick up a signal. 
I'm no computer expert, but if you can tweak your router to broadcast stronger on one signal via software (b/n/g/ac, or 2.4 vs 5.0 GHz), I'm sure something can be done with the receiver?  Apple, if you are reading this, please do something!!!  This isn't just an iOS8 issue... it has been an issue since iOS7 but no one in the Apple world believes it is an issue.  And now I hope you can see from all these postings about WiFi issue, you have to believe that it may be a software/programming issue. If the software somehow created a hardware/firmware issue, then replace our hardware/firmware please. 
Perhaps Tim Cook should get this message maybe he will respond better. What's his email address? #TimCook.  #Apple.  #iPadTurningInToABrick  #FixtheWiFiPlease
