This is only a "hardware issue" in so far as we were all stupid enough to buy crApple products. It's an issue with the iOS and there is no fix or work around that works for everyone. I've seen a dozen different supposed fixes and sometimes they work most times they do not. None of them have worked for me. It is NOT your router, don't bother resetting it, it's not a "reboot the device" problem, that does nothing except perhaps let it work for a few minutes to an hour. It's a simple matter of Apple releasing a piece of crappy buggy software and forcing us all to put up with it. You should expect no less from a company that uses slave labor to build it's overpriced products.
I strongly recommend that if you can, you sell your iPad to the nearest sucker, uh I mean buyer, and get an Android based tablet. It won't be perfect but odds are you'll be much happier. This is what I intend to do. I've already scrapped my iPhone after the update all but bricked it and I'm now going to do it with my iBrick, er iPad.
Die Apple, join your lord and master Jobs in eternal damnation!
