Hi @Arturo_Saucedo ---- Thank you for your very detailed follow up, your diligence is appreciated.
This is definitely feeling like network related issues based on the symptoms you are describing here. As you saw in this thread connections speed will most certainly have an impact on performance.
Moving forward, this kind of troubleshooting involves experimentation, temporarily configuring your network in various ways and seeing whether things improve. Eliminating potential causes one-by-one is the only real solution, and our team is ready to enumerate the best places to start.
If I was troubleshooting this, the next step would be to get everything on the floor in the middle of the room: Core machine, router, and an ethernet cable – the simplest possible setup. If you find things are more stable under this configuration, you can add in whatever complexity was removed, one piece at a time, and see where the problem recurs.
