When I run a speed check on my Apple iPhone, I get 279 Mbps on the first floor. The SBG7400AC2 is on second floor.
When in the room with the modem, I get as high as 650 Mbps.
Can I turn off the Wi-Fi on the modem, maintain the cable input and use another device for Wi-Fi with a device on second floor and another on first floor. I have an option of the first floor being hard wired if needed. This is where I use laptop and stream on main TV.
Thanks.
