I cannot update because it says I’m not connected to the interet

If you have VPN profile installed, ensure that the profile is disabled and deleted from the iPad - then force restart before attempting the update:

• On an iPad with a Home button: Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.
• On other iPad models: Press and quickly release the volume up button, press and quickly release the volume down button, then press and hold the top button. When the Apple logo appears, release the button.

Good afternoon colleen1212,

Welcome to the Apple Support Communities!

It sounds like you are trying to update your iPad to the most recent version of iPadOS. If you are getting a message that you are not connected to the internet try the following:

• Turn off your iPad.
• Unplug the power to your modem/router.
• Wait a minute, and then plug the modem/router back into the wall outlet.
• When the status lights indicate the modem/router is connected to the internet, restart your iPad.

The resources below will help you with this.
