Start the clock. (music) There is nothing worse than slow WiFi, except maybe slower WiFi than what you're paying for. Which is why getting a good router is crucial. So here are the three most important things to know when shopping around for a new router. Number one. Make sure the router supports at least two bands, 2.4 GHz and 5 GHz. The 5 GHz band is better at transmitting more data at higher speeds, but it has a tougher time getting through walls and furniture than the 2.4 GHz band. With a dual band router, you get the best of both worlds. Number two. Make sure the router supports newer wireless protocols. Basically check the specifications, and make sure it supports 802.11 AC. And finally number three. Pick the right router speed for you. Routers will have labels like AC1200 or AC3200, which is just the wireless protocol we talked about, AC, and the theoretical maximum mega bits per second the router can handle. Bigger number does not mean faster Internet. There isn't a perfect science to choosing the right speed, but the important thing is to get a router that's at least as fast as the devices you own. And that's it. Check those three things and you're well on your way to more reliable Internet and no more buffering while you're trying to watch these videos. (music). Hey, thanks for watching.
