I got the same problem. I spent almost 1 week trying to resolve this. Reboot the ipad, reboot my router, delete the network, rejoin the network. Nothing seems to work. I called the Apple support, spent 2 days. Wifi is horrible, Facetime bad quality, poor connection.
After trying everything, the Support told me to:
- Go to iTunes.Back up all your data, transfer all purchases to your computer. Of course when I tried to transfer all my purchases, they stuck for hours, then crash everything. I had to redo this 3 times. HOURS!!!
- Restore your iPad from your iTunes. It will erase everything in your iPad, then start fresh as new
- Turn off your iPad
- Turn off your router, give it 10-15 minutes, turn on your router
- Turn on your iPad, join the network
Even though finally it looks ok. I am still going to return this iPad and get a replacement. I just don't feel confident with the device anymore. I just bought my iPad less than 3 months, still got the box. The support told me I could swap my iPad, all I need is to see the Apple Genius. So I made appointment, otherwise the Genius won't see you.
I got tons of questions again from the Genius. He said it is my router problem. Basically, I have a crappy router that came from my internet provider. He said that since they opened the store, he only knew TWO people came in with WIFI issue. I told him, all my other devices connect just fine... but of course, they're "oranges" not Apple.
I thought I'll be getting my replacement right away, but no.. Genius had to place an order first, and they will call me again, and I have to make another appointment to pick it up. I wonder why they don't have one in stock. It's the NEW iPad!!! I hope they're not getting my replacement from some kinda refurbished factory.
This is my first purchase with Apple. So far it is not a pleasant experience.
