Why is my Wi-Fi just loading and not connecting?

Why is the Wi-Fi not working on my iPad but working on other devices?

I am having a really strange issue with my iPad on my Wi-Fi.

The main device I am connecting to is my router on the same room as the router and it works fine. I have my iPhone connected to that same router and it works fine but when I try to connect the iPad to the router it is not working at all. I have tried changing the setting of the wireless network to see if the problem is because the network is somehow blocked but I can't seem to be able to find the way to check it.

Go into your settings> cellular> wifi and check your connection to see if it is in some sort of conflict. Try turning off both devices if this doesn't work and then re-connect and set up a new connection.
