Hi @Serge_Libotte,
I’ve split your post into its own Topic so we can take a closer look at what you’re experiencing. So we can better assist you, please provide a brief description of your current setup using this link as a guide.
Make sure to describe your network configuration/topology, including any networking hardware currently in use, so we can have a clear understanding of how your devices are communicating.
Can you describe some examples of what kind of slowness you’ve seen? Does this occur for all remotes? Does rebooting make things faster, even if temporarily?
