Check your router settings. The main problem that people are having is their router is old and isn't set up properly! There is nothing wrong with the iPad.
If someone has a router that has worked flawlessly for years with multiple other devices and then the iPad has an issue with it, it isn't the routers fault.
Remember not all iPads are having the issue. This would lead one to believe that there was a bad lot of several thousand WiFi cards that were installed.
Apple is not moving fast enough on this.
