Stick up cam problems with a mesh system

I just installed a TP-Link Mesh system (I have the fast roaming disabled), my doorbell and my spotlight camera works perfect but the stick up cams (3) disconnect from the WIFI after 3 minutes, I need to restart them again, another 5 minutes and then disconnect, what solutions could be out there?

Our pro doorbell works perfectly with the mesh system. The stick up cams are useless.

It simply connects and disconnects at random and that’s all 3. Totally useless and ineffective!
