iPad won’t update the iOS.

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 the more recent Apple Devices App) 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

Update your iPhone, iPad, or iPod touch with the Finder - Apple Support

Apple Devices App (Windows PC):

(*) If you don’t have access to a suitable computer of your own, that of a helpful friend or family member will suffice. Alternatively, the technicians at the Genius Bar of your local Apple Store or Apple Authorised Service Provider (AASP) will be delighted to assist.

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. Update via Cellular connection, where available, requires a high-speed 5G connection.

I wiped the iPad clean. When trying to install from the backup it says the iPad needs an update. Since I don’t have computer to install the the update I’ll go to AT&T were I bought it and see what they can do to fix it.

Don't you have Wifi at home? You shouldn't need to visit AT&T to follow the process when restoring your iPad to install the update as long as you are on Wifi.

I have 5 gig up/down internet.

Wow. I didn't think anyone still had internet service with data limits anymore?

You didn’t read my post correctly. My internet speed is 5 gigs up and down.

OK. So why can't you install an update with your home Wifi? And I guess I don't understand the 5 gigs up and down. My home internet speed is 400 MBPS.

Google search suggests that there are now providers who offer 5 Gbps fiber-optic service. I'm not sure where that service is available, or how much it costs ("arm + leg"), but home Internet service with those speeds may finally be a "thing."

Note that network speeds are normally quoted in bits per second. The convention is that capital 'B' means bytes and lower-case 'b' means bits, so your home Internet speed is probably 400 Mbps (down). I do not know if your Internet service is symmetrical, or if there is a lower speed cap on uploads (as there is with many home Internet plans).

I'm just not familiar with 5 Gigs up or down service. I do know my internet service is 400 Mbps down, but nowhere close to that up. Still, if David has such fast internet, I don't understand what would prevent them from updating the iPad at home?

DMB's post in the other place indicates 2.2Gbps...

That's still VERY fast and doesn't answer why he can't update his iPad with internet speeds that fast?

I wasn't suggesting a causal factor (having already fully outlined available update methods and diagnostics); I was just clarifying his claimed internet connection speeds.

You might also note that the internet connection, as illustrated in his test result, is also asymmetric (2.2 Gbps down / 1.4 Gbps up) as might be anticipated; the majority of GPON fibre services typically have a contended (i.e. shared) uplink.

If you have a computer, use that by connecting the iPad to the computer. You are jumping 3 iOS versions which is a lot for an OTA update. If the Update option does not work on the computer, then use the Restore option which will wipe the device and let you restore from a backup.
