Can I connect my laptop to my Deco M4 satellite using a USBC hub? Also will this increase my connection speed? I have a reasonable speed; however, I would like to possibly increase it if possible. Tha

I am changing from a Deco E4 system to a Deco M4 to increase in speed. Do I need to delete my current E4 network or can I replace my main E4 unit with the new M4 unit? Thanks for the help.
