Yes - the orbi seems to provide a wi-fi signal (and download speeds) that is close to, if not equal to, that of a wired connection. I have 105/10 internet service and I get about 105-111 download wired and wirelessly with ORBI I get 85-90 about 30 feet from the router and any closer than that, I get around 100-105, so almost no difference. When you factor in 2 units (one router with an additional satalite) you get that same speed over a meshed area of 60+ feet.
If you have a decent Internet connection, trust me, the issue is with your router and the router will always be the weak point, ORBI gets you a lot closer to 100% of what your fiber is providing to your home/office.
