iPad will no longer connect to internet after installing iOS 15

Your issue is unlikely to be WiFi per-se, but more likely a problem obtaining a valid IP Address for your network.

If you have a VPN App or profiles installed, or a security App such as Norton, these may be interfering with DHCP - and may need to be temporarily disabled.

DHCP is frequently used to automatically obtain an IP Address from your WiFi Router. Until your iPad has a valid IP Address to connect to your network, you will not have an internet connection. Disabling or removing VPN and/or the offending security App should allow DHCP to operate normally - allowing connection to your network and the internet.

If this resolves your issue, the VPN and/or security App can be reinstated after the connectivity problem has been resolved.

Hi mallenbrand,

Thank you for participating in the Apple Support Communities. If you used the article attached to this post and determined that your device was compatible with iOS15, try restarting the device to see if the refresh resolves the issue. If the issue persists, check out If your iPhone, iPad, or iPod touch won’t connect to a Wi-Fi network.

Have a great day.
