I just had fiber installed to my house and when I am connected via wi-fi to the fiber provider's router I am getting speeds of 823MB download and 580MB upload. I have a CAT6 patch cord connecting to my Deco router but when I do a test speed connected to it (the Deco router) I am only getting speeds of 323MB download and 9.63MB upload (and this is on the 6GHz network). My phone, which I am using to do both tests, is right next to both routers. Anyone have any ideas on why?
