Wi-Fi drops internet connectivity randomly after upgraded to iPad OS 18.4

Recently my iPad OS got updated to 18.4, since then the Wi-Fi appear connected, but cant access internet, it keeps losing internet connectivity randomly. I've re-started my gateway, restarted iPad, but nothing seems to resolve the issue. Other device using the same access point do not have this problem.

This issue appeared during some early 18.x versions, and was fixed. Now its back again with iPad OS 18.4. This is very frustrating and my iPad is almost unusable. It's really disappointed, that a fixed issue has re-appeared in the latest iPad OS version.
