MacOS randomly disconnecting from WIFI

I have a weird issue with MacOS (Catalina 10.15.4, MacBook Pro 15-inch, 2019) disconnecting from my WiFi (Ruckus R500). I have started "Wireless Diagnostics" to see what the problem is, but I couldn’t find a clear problem.

The problem is specifically the case of the macbook and Ruckus R500. I have other (Windows) laptop that works well on this WiFI and doesn’t drop. I also use this macbook at work where we have Ubiquity Unifi AP and it doesn’t drop there.

As I’m no expert in this, I don’t know what I should be providing – happy to have feedback from the community, but below are some of the information I got from diagnostics.

Here are some error strings I found in from wifi log:
