How to unblock wireless connection with Zoom?

Question

Computer networks

The bottom line: The organization hosts conferences in Zoom. With a wired connection, there are no problems, he just enters the conference and it works. But, if you try to connect via Wi-fi from the same router (MicroTik). Then Zoom responds either with endless downloads, or says to check the Internet connection. Any computer on the network has a problem, so the problem is in the router. I connected to it via ip, but there are a million settings, it’s difficult for me to understand them. Give advice where it is better to dig or the solution to the problem itself? I myself found only ports that should be open for connection ( https://support.zoom.us/hc/ru/articles/203680389-K... ).
