I have a new iPad, replaced via apple care. Why can’t I hook up to WiFi

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

Can you, please, confirm what year and model iPad do you have/own?

The “A” model number can be found on the aluminium back of your iPad, in very small print, right under the larger bold print “iPad” on the back of the iPad.

What iOS/iPadOS version is this iPad, currently, running?

What is the rated, internal data storage space/capacity of your iPad model

Please try to attempt to answer all questions asked.

Why can't you setup WiFi on your WiFi network?

What happens when you try?

Thank You.
