I'm not impressed with the articles about overheating. I don't care what the temperature readings say. It's hot and it's not comfortable to hold it.
As for the wi-fi, I've tried resetting network settings, restarting the ipad, changing rooms - and all of those strategies work... for awhile. Then they don't. It's working fine as I write this response, but I know it'll stop working in a little while.
Apple is supposed to provide top of the line products. Most of the time they do. But this one isn't living up to Cupertino standards.
I'll give up the speed and the screen and the LTE and the good cameras, go back to the iPad 2 and actually put some money back in my pocket - UNLESS someone tells me that a software update is going to fix my problems before my 14 days to return it.
As for router settings - I don't think that should matter. I'm going to want wi-fi to work at Starbucks, hotels or wherever I go and I certainly won't have any ability to adjust the modes on their wi-fi networks.
Oh look. I just got kicked off of wi-fi again. ****.
