Can't download the latest software update on iPads.

If your iPad is capable of update to a more recent version of iOS/iPadOS than is currently installed, these support pages outline both the available methods by which the update can be performed - and troubleshooting should you experience difficulties:

Update your iPhone, iPad or iPod touch – Apple Support

If you can't update or restore your iPhone, iPad or iPod touch – Apple Support

If your iPhone, iPad or iPod touch won’t update - Apple Support

iOS update and restore errors – Apple Support

Be aware that while an iPad may be capable of update, in some circumstances you may need to use a computer to perform the update. To do so, you will need access to either a Windows PC (with iTunes for Windows installed) or a Mac (with iTunes or Finder - as appropriate for the installed version of macOS). Ensure that your installed version of iTunes has been updated to the most recent version; the essential device drivers are included.

Download and use iTunes for Windows – Apple Support

Update to the latest version of iTunes – Apple Support

Update software on iPhone, iPad or iPod touch in iTunes on PC - Apple Support

If you have a beta profile installed, ensure this has been removed from your iPad - as, otherwise, installation of production software updates may be inhibited. This support page provides the necessary information to remove the beta from your iPad:

How to uninstall iOS beta software - Apple Support

You should note that for your iPad to install an available update, its battery must be charged to at least 50% capacity - and/or be connected to its Power Adapter. Similarly, the iPad can only be updated over a standard WiFi connection - or be updated by a PC or Mac using iTunes or Finder - over a USB connection.

I to have the same issue with our iPads. I’m on Wi-Fi but update says I’m not and won’t update. This is the second update in a row this has happened to me with updates. The recent update worked on 14pro max on same Wi-Fi. On separate note I’ve also have trouble backing up my iPad Pro on the cloud. Says same bad Wifi or no Wi-Fi connection. I haven’t been able to back up the tablet in weeks. It is definitely a their problem not an our problem situation I can assure you.

Your Wi-Fi must not use VPN. It must not be a Hotspot. It should not use anti-virus protection. And the iPad battery should be well charged or plugged in to power.
