Yeelight connection problem - time out

Hi, I got 2 yeelights color s1 and somehow, a member in my family change the router security setting to to WPA3. Now the mi control hub loses the access to the router as well as the 2 yeelights. I switched back to WPA2 and now it could not connect to wifi anymore.

I did set my router to 8.8.8.8 / 8.8.4.4 already

Here is my MI ID: 6319916501
