Xiaomi Note 11 Pro, Update Problems, Seeking Solutions

Since I bought my gadget last year,  no trouble-free experience with it at first. I thought it was a good balance between functionality and efficiency, and met my needs. But software upgrades are a constant part of the development cycle for new technologies. In this situation, I've run into some problems after upgrading to version 14 and looking for advice on how to fix them. Before this upgrade, my gadget worked fine; I appreciated the ease of having Wi-Fi and strong network reception. But ever since I installed update 14,  my phone's Wi-Fi connection and network signal have begun to malfunction. Obviously,  this development is not what it's meant to be. I'm at a loss as to what to do. Should I contact Xiaomi's support team? Should I hold off for an update that maybe fixes these brand-new issues?  there has to be something I can do...
