Need to download iOS 8.0.1 on my apple ipad keeps telling me it failed because I am not o internet, but I know that I am connected to the iternet what is wrong?

be sure to check your available memory AND be sure your ipad is PLUGGED IN to the electricity to continue full download (this is a must)

To update you will need:
1 iOS tablet (iPad, etc)
1 wifi internet connection
1 power source

1. power on your tablet device.
2. connect to the wifi internet connection.
A. Open settings
B. Open general
C. Select "software update"
You should now see what update is available. If you are below iOS 7, you will need to update to version 7 to be able to see iOS 8 as available on some devices.
3. Locate iOS 8.x.x (on my tablet it is 8.1.3 as I wrote this)
Make sure your tablet is plugged into a power source (you don't want it to lose power while updating)
4. Under the iOS update you want to install, select "install now" "download now" or "download and install"
5. Select "agree" when presented with the terms and conditions

You should see your device "downloading update" or "verifying update"

I have seen occasions where it will download but will not install until the process is repeated. (On one device I had to "install now" 3 times because the update failed to download or failed to install.

My iPhone upgraded fine. Try a hard reboot - hold power and home together until it goes off, keep holding until you see Apple logo then release and let it finish booting. If that doesn't work, may need to force a reinstall of the update via iTunes.

because it has a size of over 1GB - download time depending on the internet connection speed:
