These devices are intended to be connected to, and expand another network that is using a router. The router's only job is to connect one network to another and handle data traffic between the networks.
In most consumer cases, the two networks the router is connecting are the local network and the Internet. Routers can also be used to bridge several smaller networks in the same building or general area for cross-device communication. A Wi-Fi network without a router will not be able to communicate with other networks as a single entity. Sharing an Internet connection with several Wi-Fi connected devices over a network that doesn't have a router will usually end with only one of the devices being able to connect to the Internet at a time.
Internet service providers usually only assign accounts a single IP address -- without paying extra -- that's used to identify all incoming and outgoing traffic on the Internet connection. Routers work around this limitation by claiming the IP address and acting as traffic control to direct data to the correct devices on the network.

Routers bring the Internet to your devices A router connects your devices to each other and, in hard-wired connection setups, to the modem.
Simply put, your router: Assigns a local IP address to each device on the network Creates a firewall to prevent security breaches Manages the traffic on your network Handles any Parental Controls Do I need a router and a modem?

Tri-band routers broadcast three signals, which currently means two on the 5-GHz band and one on 2. Each of these bands is essentially a chunk of frequency. The 2. The 5-GHz band has 45 channels, but they aren't limited to 20 MHz; they can also be bonded together to create MHz or MHz channels, which allows them to transmit more data.
The 6-GHz band supports 60 channels and they can be as wide as MHz. The main difference is that 2. It's like jumping from a single-track road 2. Each of the protocols is backward compatible. Any router you choose nowadays is likely to be at least dual-band, but you may want to check how the bands are handled. It was common to have the bands appear separately, so when searching for Wi-Fi on your device you might see two options like Wi-Fi 2.
Modern routers such as Google's Nest Wifi engage in band steering, where they automatically pick the band, and you only see a single Wi-Fi network. This is simpler and will work well for most people, but it can cause issues when setting up smart home devices that can only connect to one band, as they often also require the device setting up usually your smartphone to be on the same band.
Some devices require a wired connection to your router. Even when it's not needed, an Ethernet cable is always going to offer more stable connections that are much faster than Wi-Fi.
If you can, you should try to use a wired connection for devices like PCs, TVs, and consoles so you can leverage the fastest speeds out of your router. Either way, you'll need a free Ethernet port, so make sure you check that your router or mesh system has enough of them.
Several high-end mesh systems, such as Nest Wifi or Eero, only have a single Ethernet port on the main router and none on the nodes. If your chosen router doesn't have enough ports, you can get a network switch. These devices are relatively cheap and give you a few extra Ethernet ports. It's vital to secure your Wi-Fi router , because all traffic in and out of your house goes through it, and every device connects to it.
It offers reasonably strong encryption but is not without vulnerabilities, which is why it was followed by WPA3 in For example, opportunistic wireless encryption OWE provides a separate decryption key for every device that connects to the router, so even if another device on the network is monitoring traffic known as sniffing it can't decrypt that data.
WPA3 also makes it much tougher for hackers to crack passwords, as they can't use offline dictionary attacks anymore where they rapidly guess lots of possible passwords.
You can find Wi-Fi 5 routers with WPA3 support, and some manufacturers are rolling it out onto older devices via firmware updates. It is also backward compatible. No security standard is perfect, so you should make sure your router has automatic updates turned on and always install the latest security updates on any devices you own.
Another feature to look for is a guest network, so you can hook guests up with Wi-Fi without giving them access to the rest of your network and all your connected devices.
While older routers tend to have basic settings you can only access by entering the IP address into your browser and logging in, many new routers and mesh systems offer apps you can access on your phone. It's worth taking a look at the interface to make sure it has all the features you want. We suggest reading our reviews and user reviews to get a feel for how well it works and to identify any potential problems.
The latest mesh systems boast accessible apps that show all connected devices at a glance. You may find the option to pause the internet, create schedules, and the ability to organize devices into profiles. Many also include parental controls, so you can block different types of potentially sensitive content and block or white-list specific websites. Some companies charge extra for these perks, so keep an eye out. Quality of service QoS is an underappreciated feature worth looking into, particularly if you have a busy household with several people using the internet.
Imagine a video call for work gets choppy or disconnects because your kid starts streaming Netflix. Perhaps the movie you're watching starts to buffer when your roommate begins downloading a game update. With QoS, you can prioritize devices and sometimes services or activities. You might dictate that your work PC is the priority device, for example, ensuring it has the most bandwidth to reduce the risk of stuttering calls.
Some routers enable you to prioritize activities like gaming to minimize latency and ensure the smoothest possible experience.
