error message not connected to the internet when updating ios9

Hi pzmachelp,

Thanks for using the Apple Support Communities! I'm sorry to hear you are having this issue with your iPhone. I also apologize, I'm a bit unclear on exactly what you are describing or how you are updating your iPhone. If you are attempting to update it wirelessly (also known as over-the-air) via a WiFi connection, you may find the information and troubleshooting steps outlined in the following articles helpful:

Update the iOS software on your iPhone, iPad, or iPod touch - Apple Support (first half)

Get help with over-the-air iOS updates - Apple Support

If your iPhone, iPad, or iPod touch won’t connect to a Wi-Fi network - Apple Support

On the other hand, if you are updating your iPhone via iTunes, you may find these articles more useful (in particular the second article):

Update the iOS software on your iPhone, iPad, or iPod touch - Apple Support (second half)

If iTunes can't contact the software update server for iPhone, iPad, or iPod - Apple Support
