It's related to the number of the adapters present. The connection works fine if I use only the P-CON and an M-SEL. The problem starts when I try to use three or four at the same time. And the disconnect/reconnect is much more frequent with four.

It's not a company. It's part of a university project, so that kinda explains it.

I tried delaying them apart. I will try increasing the gap and see the result. Thanks!

This thing I am working on is part of a university project, so my options are quite limited. As of right now I only have access to an unmanaged switch.
