Greetings MartinaElv,
Thanks for visiting the Apple Support Communities! I understand your iPad is unable to connect with one of your Wi-Fi networks.
The following support article provides helpful troubleshooting suggestions for when an iPad won't connect with a Wi-Fi network: If your iPhone, iPad, or iPod touch won’t connect to a Wi-Fi network
If the issue persists after attempting the suggestions within the guide, it would be helpful to know if your iPad connects with other networks as expected.
Kind regards.
