Problem To Connexion On Mikrotik Server

Problem connecting to the mikrotik server when I put the access points and desktops on the same switch but when I remove the access points, the connection works perfectly on desktops

One of your ap’s may have a faulty port causing a network loop.

Try and plug them in one by one to find the faulty one

I have installed KERIO CONTROL in place of MIKROTIK it works very well.
Thanks for helping me to work with MIKROTIK ROUTER PC.
