Wi-Fi Issues After One UI 7 Update on S21 FE and Tab S9 FE+

[m_pathira]

After updating to One UI 7, I’ve been facing frequent Wi-Fi disconnection issues on both my Galaxy S21 FE and Tab S9 FE+. The Wi-Fi disconnects on its own, and when I try to reconnect, it fails to connect for a while.

I was using AdGuard DNS earlier, but I’ve already disabled it. I’ve also reset the network settings on my phone, but the issue still continues.

Is anyone else experiencing this? Any suggestions or fixes?

Yes, this seems to be happening in multiple devices. I am also facing it on S25 Ultra, S24 Ultra and S22 Plus

The issue occurs only on devices that have been updated to One UI 7. My other Samsung devices that haven't received the update are working fine without any problems.
