My iPad won’t stay connected to wifi. This started immediate after I updated to IOS 15. This is terrible. I really don’t want this. Can I go back to IOS 14? Or at least get afic for this. It will connect for a few minutes and then jump away.

Did you try the MODEM reset?

I'll start asking this.

Do you use a VPN?

If you are uncertain of how to configure or disable features of the Norton Security App, simply delete the App from the iPad - and then restart the iPad.

Delete apps on your iPhone, iPad, and iPod touch - Apple Support

VPN connection profiles installed by an App can be similarly removed. You can reinstall Apps, as needed, when network connectivity has been restored.

Many reports here of iPads that will not connect to WiFi/Internet after the iPadOS 15 upgrade, no matter what is tried.

Possibly a bug.

Try everything listed below.

After any iOS/iPadOS upgrade/update, you should ALWAYS perform a simple hard reset of your Apple mobile device.

For older iPad models with a Home button, do a simple hard reset of your iPad by holding down both the Home and sleep/wake/power button simultaneously until your iPad goes to black and restarts with Apple logo, then release the buttons.

OR

For much newer, larger screen iPad models, without a Home button, try the new simple hard reset procedure for the new 2018/2020/2021 iPad Pros and the 2020 iPad Air 4 models.

1. Press and release the volume up button.

2. Then immediately press and release the volume down button.

3. Then, press and hold the single sleep/wake/power button You will see the Slide to Power off button, but keep on holding down the power button until you see the Apple logo, then let it go.

Once you have performed all the steps, wait for a few seconds and your 2018 iPad Pro will boot up completely to the iPad Pro’s Lock screen.

Then, do a simple reset of the Home wireless/WiFi network MODEM/router box by unplugging from power for 15-20 seconds, or so.

Then re-plug into power and let the MODEM/router box simply re-cycle itself.

Best of Luck to You!

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. Alternatively, you can manually set an IP Address and Default Gateway (Router), appropriate for your network, from iPad settings.

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

You are very welcome.
