Use this router at home with 3 devices streaming movies and videos at the same time and I have no issues. Have 10 devices on wi-fi with no lag. Great User Interface for setting up your router though the Genie App. Very easy to set-up a secure network at home.
Was having so much trouble with the old router that my husband did some online research and found that this brand was supposed to be superior. We do agree.
Got a router for my studio, it's on the 3rd floor and I get clear signal on the ground floor. It was easy to setup and the app is great to track usage (even remotely). All in, though pricey, it's a great buy.
