“At most my speed from Xfinity is 70mbs via ethernet cable.”
Are you using CAT5e or CAT6 cabling? I would think you should get a better speed than that.
CAT5e cable from the router to my desktop that I am using right now. The fastest I ever get with this is 75mbps but I am paying Xfinity for only a 75mbps internet connection. Not for any higher speed. I don't have a home network setup. My laptops and desktop connect to my router independently. My laptops via wifi. Desktop via ethernet cable.
