Which managed 16 port switch should I choose?

Question

Computer networks

At the facility, the network was built in such a way that lines from Wi-Fi routers converged into a common unmanaged switch, each located on its own floor under the ceiling. These routers are not built to work in access point mode; in turn, lines from users were connected to them. Instead of an unmanaged "master" switch, they installed a Cisco Catalyst 3750. The network is divided into subnets. The question arose with the devices on the floors. It is also necessary to ensure the division into subnets. For these needs, HP OfficeConnectSwitch 1820 8G J79979A switches were purchased. There were problems with them, they were unstable, the trunk port was turned off, in the logs there was only a message about an unexpected reboot. Updated the firmware, did not help for a long time. A few days later the situation repeated itself. Sent to the store. Instead of the given one, a D-Link DGS-1100-08 switch is temporarily installed. This switch works better, but sometimes the web interface does not respond for a long time. In the process, the network grew a little and 8 ports on one floor are not enough. Please help me choose a reliable managed switch for 16 ports. In addition to the possibility of splitting into vlans, there are no more special requirements.
