I hate that I've become an AT&T fanboy, but I have their Gigabit fiber service and use their router. The modem/router they gave me -- and don't charge an extra fee for it -- is in the worse possible place in my two story house. It's in a guest bedroom closet downstairs attached to the smart panel.

When I'm right under it, I can get 400Mbps u/d from my iPhone and my laptops. In the worse location in the house I get 120/120. My house is wired for gig-e throughout but I with that kind of wireless speed, I didn't bother about getting the more expensive Roku boxes with 10/100 Ethernet connections.

Of course I usually get 900+ u/d wired.
