These days your Wi-Fi router not only connects you to the Internet, but often your job, too. Here’s what you need to build the best home network along with reviews of our top-rated routers for a range of needs and budgets.
With COVID-19 still keeping so many people working from home, your Wi-Fi router is doing a lot more than helping you stream movies and play games. Home Wi-Fi routers keep millions of people working and they’re also connecting an ever-growing range of smart home devices. That means picking one that does the best job for both you and your wallet is trickier than ever, especially now that we’re seeing more Wi-Fi 6 devices becoming available. When you’re shopping for a new router, it’s best to start by considering the size of your coverage area and the number of clients you need to support as well as the types of devices that you’ll be connecting. Not everybody needs the kind of performance that you get with the latest and greatest models, and there’s no reason to pay for features that you will likely never use; so if you’re looking for a lower price rather than a big bag of bleeding edge features, check out this list of budget routers. But if you have several family members vying for bandwidth for things like streaming Netflix video and playing PC games online, a new router with modern management capabilities can make a world of difference and help keep the peace. Below we guide you through choosing a router that will handle your current and future wireless networking needs, and offer our top picks to get you started. Understanding Wi-Fi Bands Nowadays, any router worth its salt will offer at least two radio bands, a 2.4GHz band and a 5GHz band. The 2.4GHz band operates at a lower frequency than the 5GHz band and offers better range because it is more adept at penetrating walls and other structures. However, is doesn’t offer the fat pipe and high speed access that you get with the 5GHz band. Additionally, the 2.4GHz Wi-Fi band has to compete with other devices in the home that use the same frequency, such as microwave ovens, Bluetooth devices, and wireless phones. That said, it is perfectly adequate for tasks like Web surfing and connecting to social media services like Facebook and Twitter. If one or more of your devices will be streaming video from a service such as Netflix, or connecting to an online gaming service such as Xbox Live, the less crowded 5GHz band offers significantly more throughput with minimal signal interference. Most dual-band routers allow you to assign a band to specific applications and clients, thereby easing the load on both bands. If you have a busy network with numerous clients vying for bandwidth, a tri-band router is the way to go. They use three radios—one that operates at 2.4GHz and two that operate at 5GHz, for load balancing. For example, you can dedicate one of the 5GHz bands to handle tasks like video streaming and torrent downloading and reserve the other 5GHz band for online gaming, leaving the 2.4GHz band free for applications that don’t require lots of bandwidth. If you have a house full of gamers, we have a specific best routers list for you. Finally, there’s the new 6GHz spectrum, recently made available by the FCC. While this new spectrum promises a significant boost to overall wireless network performance, the devices you’ll see supporting it for the next 12 months will be few. Those that do appear will be early adopters, so take performance claims with a grain of salt and try to avoid solutions built around entirely proprietary “standards.” For more, see our story on What Is Wi-Fi 6E? Wireless Protocols Wireless Ethernet networks use 802.11 protocols to send and receive data. The most widely used Wi-Fi protocol,802.11ac, allows for maximum (theoretical) data rates of up to 5,400Mbps and operates on both the 2.4GHz and the 5GHz bands. It utilizes Multiple Input Multiple Output ( MIMO) technology, which uses several antennas to send and receive up to eight spatial streams, resulting in enhanced performance. It also supports beamforming, a technology that sends Wi-Fi signals directly to a client rather than broadcasting in all directions, and automatic band-steering, which lets the router select the most efficient radio band based on network traffic, band availability, and range. The 802.11ac protocol also offers downstream Multi-User MIMO ( MU-MIMO) technology, which is designed to provide bandwidth to multiple devices simultaneously rather than sequentially. That means up to four clients can have their own data streams instead of waiting in turn to receive data from the router. In order for MU-MIMO to work, the router and the client devices must contain MU-MIMO Wi-Fi circuitry. Routers that support MU-MIMO are widely available but the fact that consumers have been slow to understand exactly what the benefits of MU-MIMO are has kept the number of client devices somewhat scarce. You’ll see 802.11ac routers with labels like AC1200, AC1750, AC3200, and so on. This designates the theoretical maximum speed of the router. For example, a router that can achieve a maximum link rate of 450Mbps on the 2.4GHz band and 1,300Mbps on the 5GHz band is considered an AC1750 router. A tri-band AC3200 router gives you 600Mbps over the 2.4GHz band and 1,300Mbps over each of the two 5GHz bands, and an AC5400 router is capable of speeds of up to 1Gbps on the 2.
