Thank you very much for the answer I found a solution! It was DNS problem after all. It was somewhat interfiereeng with my pi-hole DNS server, I've changed it and now everything is working well.

I'm not familiar with the product so just general answers. Looking at the data sheet it's paid subscription support but has limited lifetime warranty if the hardware is faulty https://www.cisco.com/c/en/us/products/collateral/wireless/business-100-series-access-points/smb-01-bus-140ac-ap-ds-cte-en.html
You haven't given much info to work with so:
- Make sure you're using the latest firmware: https://software.cisco.com/download/home/286324956/type/286325362/release/10.3.1.0 (always read the release notes before embarking on upgrade)
- Check through the documentation for any tips: https://www.cisco.com/c/en/us/support/wireless/business-100-series-mesh-extenders/series.html#~tab-documents
Disconnects like that could be firmware bug, AP crashing, something causing interference, poor choice of channel overlapping with neighbours ... You need to methodically eliminate those things. If that's beyond your skills you'll probably need to find someone who is more familiar with wireless troubleshooting and ideally has tools to capture what is happening when you see a disconnect. Maybe the AP logs will show you something interesting.
