Start with basic WiFi troubleshooting - as detailed here:

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

Recommended settings for Wi-Fi routers and access points - Apple Support


Consider that your new WiFi Router/Modem, to which you are attempting to connect, may be configured by default to require support for security features that are not supported by older versions of iOS. If your router is configured for WPA3 authentication, you will need to change this to WPA2 PSK.


If your WiFi has been set-up according to Apple’s recommended settings, WiFi and Internet connection difficulties are usually an indication that your device does not have a routable IP Address - your IP Address usually being assigned by DHCP. When this occurs, your iPad may only have a self-assigned link-local IP address that begins 169.254.x.x.


If you have a VPN App or profiles installed, or a security App such as Norton, these may be interfering with DHCP - and preventing your device from obtaining a valid IP Address for the WiFi network/hotspot to which you are attempting to connect. The resolution is usually simple; if installed, you may only need to temporarily disable or remove the Security App and/or VPN.
