Arris SB6190 and Linksys WRT1900AC bandwidth dropoff with gigabit xfinity service
I have a the xfinity gigabit service with an Arris SB6190 cable modem that gives me consistantly 325MBS-400MBS when I connect an ethernet cable directly to my windows 10 laptop. When I then connect the cable modem to my Linksys WRT1900AC wireless router my wireless speeds drop down below 35MBS even when I'm standing next to the router (2.4 ghz and 5ghz are both below 35MBS ). I have 2 laptops (1 windows and 1 chromebook) 2 tablets (not always connected), 3 nest cameras (i tested it with all 3 cameras turn off). Do I need to upgrade to the Arris SB82000 to get the wireless speeds I should be expecting (50M-100M) at a minimum. PLease help.
