Wifi Dead but "connected" in settings

Same here. I tried all the items you can find on the support article- brightness, disabling a band on my dual band router, the lot- no help.
The workaround seems to be to go in settings and turn wifi off and on again.
However I have solved it for me by using another wireless router I had.

So it seems to be router specific in some way (mine was a belkin) but I would still categorize it as apple's resposnisbility. They are keen to make a fix (they emailed me directly when they saw my post here, and they chap on the phone was very helpful) so I would expect one soon.

I would suggest- try all the suggestions in the support article you will find if you google for iPad wifi problem, if those don't work either change your router (perhaps to an apple airport), take it back for a refund or tolerate it and wait for the fix.

My wifi at home would not connect and all the settings were correct. I struggled with this backing up and restoring my ipad, etc. Finally, on the wifi settings page, I clicked the "forget this network" tab and then simply re-entered the information to connect: IT WORKED.
