This year, choosing a router is no longer a simple matter of buying a "box with antennas." The networking equipment market is undergoing a revolution in standards, and models that were considered top-of-the-line just yesterday may now struggle to cope with increased internet speeds and the number of connected devices. In 2021 It's critical to consider not only price, but also support for new security protocols, the availability of Gigabit Ethernet ports, and, of course, operation in the 5 GHz frequency range.
Many users mistakenly rely on devices provided by providers, forgetting that rented router Often a compromise solution with limited functionality. Purchasing high-quality equipment yourself is an investment in stable video conferencing, lag-free gaming, and the ability to intelligently distribute traffic across dozens of devices. Let's figure out which parameters to look for first to avoid overpaying for unnecessary things and skimping on essentials.
The key factor in choosing this season is the implementation of technology WiFi 6 (802.11ax)While this standard was previously found only in flagship models, in 2021 it's becoming mainstream, providing real data transfer speeds even in densely populated areas where the airwaves are clogged with neighboring signals. Ignoring this trend no longer makes sense if you plan to use your equipment for several years without upgrading.
Wireless Standards: Why WiFi 6 Matters
The first thing a customer encounters in a store is the abbreviations of communication standards. For a long time, it was dominant WiFi 5 (802.11ac), which provided decent speed, but in the conditions of a modern "smart home" its capabilities are being depleted. The next-generation protocol, WiFi 6, offers not just a boost in maximum speed, but a fundamentally different approach to handling multiple connections.
OFDMA technology, the foundation of the new standard, allows data to be transmitted to multiple devices simultaneously within a single channel, rather than sequentially. This means that while one user is watching 4K video, another is playing an online shooter, and a third is downloading updates, the router doesn't create data packet queues. Latency (ping) in such a situation remains minimal, which is critical for interactive applications.
⚠️ Attention: To operate at WiFi 6 speeds, your client devices (smartphones, laptops) must also support this standard. However, even if you have older equipment, purchasing a WiFi 6 router makes sense: it manages traffic from older devices more efficiently and has a more powerful processor.
In addition, new routers of 2021 are often equipped with modules NFC for fast connection and improved beamforming algorithms that direct the signal directly to the device rather than scattering it in all directions. This significantly improves coverage in distant rooms.
Single-band or dual-band: the eternal dilemma
Dividing routers into single- and dual-band remains one of the most important selection criteria. Models that operate exclusively in the band 2.4 GHz, can be considered obsolete for use in apartment buildings in 2021. This range is heavily congested, with microwaves, Bluetooth headsets, and dozens of neighboring networks operating in it, leading to constant connection drops.
Dual-band (Dual-Band) devices broadcast two networks simultaneously: the familiar 2.4 GHz for older gadgets and smart home devices, and the fast 5 GHz for basic tasks. The 5 GHz frequency has a shorter range to penetrate walls, but offers wide channels and a lack of interference. It is at this frequency that the manufacturer's claimed high speed is achieved.
- 📶 2.4 GHz: It penetrates walls better, but has low speed and high noise levels.
- 🚀 5 GHz: Provides maximum speed and stability, but is less effective at penetrating concrete floors.
- 🔄 Smart Connect: A feature that combines both ranges into one network, automatically switching the device to the best signal.
When choosing a model, pay attention to the availability of the function Smart Connect or similar names from different brands (Band Steering). It eliminates the need for the user to manually switch between "MyWiFi" and "MyWiFi_5G" networks when moving from the living room to the bedroom. The router automatically decides which frequency is best for a particular device at any given moment.
Network Topology: Mesh Systems vs. Repeaters
If your home is larger than 60-70 square meters or your walls are made of reinforced concrete, a single router may not be enough. Repeaters (signal boosters) were the solution in the past, but in 2021, repeaters are becoming the de facto standard. Mesh systemsUnlike repeaters, which cut speed in half and create a separate network, mesh nodes form a single, seamless network.
The main advantage of mesh technology is roaming. You can move around your home while video calling on your smartphone, and switching between nodes will occur seamlessly, without interrupting the connection. The system automatically creates the optimal route for data packets, choosing the fastest path to the main node connected to the provider.
The cost of two- or three-module kits has become significantly more affordable this year. Many manufacturers, such as Tenda, TP-Link, and Xiaomi, offer modular systems that allow you to purchase additional units as your living space expands. This is a flexible solution that scales with your needs.
⚠️ Attention: When purchasing a mesh system, look for a dedicated backhaul channel. In tri-band models, one 5 GHz band is reserved exclusively for communication between modules, ensuring no speed loss on client devices.
It's also important to note that some modern Mesh systems don't have physical LAN ports on the satellite modules, relying solely on wireless connections. If you need to connect a desktop PC or TV set-top box in a distant room via cable, choose models with Ethernet ports on each node or use Powerline adapters.
Hardware Matters: Processor and Ports
A router is a fully-fledged computer with its own operating system, and its hardware determines how quickly it processes traffic. In 2021, the minimum required standard is gigabit WAN and LAN ports. Fast Ethernet ports (100 Mbps) are a bottleneck that will prevent you from using internet plans higher than 100 Mbps, even if your provider offers them.
RAM capacity (RAM) also plays a role. Budget models with 64 or 128 MB of memory can choke when simultaneously downloading torrents, watching IPTV, and using a smart home device. Devices with 256 MB of RAM or more are the optimal choice. They can maintain stable uptime for weeks without requiring a reboot.
| Characteristic | Budget segment | Middle segment | Top segment |
|---|---|---|---|
| WiFi standard | WiFi 5 (AC1200) | WiFi 6 (AX1800) | WiFi 6 (AX5400+) |
| WAN/LAN ports | 100 Mbps | 1 Gbps | 2.5 Gbps and above |
| RAM | 64-128 MB | 256 MB | 512 MB - 1 GB |
| Antennas | Non-removable | Removable / High Gain | Multi-band / Internal |
The presence of ports deserves special attention. USBIn 2021 routers, they are often used not only for connecting 3G/4G modems (which is becoming less relevant), but also for setting up home NAS storage or connecting a printer. However, the speed of USB ports in routers is often limited, so it's better to use specialized devices for working with large files.
Why does a router need a powerful processor?
A powerful CPU (such as a quad-core processor from Broadcom or Qualcomm) is needed for more than just WiFi speed. It also handles traffic encryption (VPN), parental controls, antivirus protection, and prioritization of gaming traffic without sacrificing network performance.
Security and software
In the era of remote work and online banking, home network security is becoming increasingly important. Manufacturers are focusing on built-in security systems in 2021, with technology leading the way. WPA3, which replaces the vulnerable WPA2. It protects against brute-force attacks and encrypts traffic even on open networks (if the router supports OWE).
Many brands, for example Keenetic And ASUS, offer free firmware updates for years, patching security vulnerabilities. This is an important criterion: when buying a router, you need to be confident that the manufacturer won't abandon it a year after the release of a new model. Regular updates are a sign of a quality product.
- 🛡️ Built-in antivirus: Check traffic for viruses and phishing sites in real time.
- 👨👩👧 Parental control: Flexible scheduling and content filtering settings for children's devices.
- 🏠 Guest network: Isolated access for guests without access to your personal files and printers.
Don't forget about the possibility of installing alternative firmware, such as OpenWrt or DD-WRT, although in 2021, manufacturers are increasingly blocking this feature on new chipsets. For the average user, a convenient mobile app that can quickly change a password, test the speed, or disable an untrusted device is more important.

Popular brands and models of 2021
The router market in 2021 is represented by several key players, each occupying its own niche. TP-Link continues to hold the lead in sales volume thanks to its line Archer, offering excellent value for money and features. Their new models support HomeShield provide basic security features for free.
Brand Keenetic (formerly ZyXEL) has earned a reputation as the most reliable solution for demanding users and small businesses in the CIS. Their software allows for flexible priority configuration, backup communication channels, and complex routing schemes. It's the choice for those who value stability over a beautiful but simple interface.
Company Xiaomi is aggressively capturing the market by offering some of the most affordable WiFi 6 routers. Models in the series AX3600 And AX1800 They have become bestsellers, although their software sometimes requires a bit of a rigmarole during initial setup (in China). Nevertheless, for the price, they offer impressive performance.
⚠️ Attention: When purchasing Xiaomi routers, pay attention to the version's region (Global or CN). Global versions have an English interface and servers in Europe, while Chinese versions may require a Chinese language or a VPN for setup via the app.
Also worth mentioning ASUS and their game series RT-AXThey often come equipped with additional features for gamers, such as game package prioritization and a free antivirus subscription. For Apple device owners, systems remain an excellent, albeit expensive, choice. Apple AirPort (if you can find one on sale) or compatible Mesh systems with HomeKit Secure Video support.
Frequently Asked Questions (FAQ)
Should I change my router if I'm not happy with my current one?
If your current router only supports 2.4 GHz, has 100 Mbps ports, or constantly requires a reboot, it's definitely worth replacing. You'll immediately notice an increase in speed and stability, especially if your internet plan exceeds 50-100 Mbps.
Can a router increase internet speed?
A router can't increase speeds beyond those provided by your ISP. However, it can eliminate bottlenecks if your old equipment wasn't capable of reaching the maximum speeds offered by your plan. For example, upgrading from Fast Ethernet (100 Mbps) to Gigabit (1000 Mbps) will provide a tenfold increase.
Where is the best place to place a router in an apartment?
The ideal location is the geometric center of the apartment, located as high as possible (on a cabinet or shelf). Avoid placing it near microwaves, mirrors, and metal structures that shield the signal. Don't hide the router in a low-voltage panel or behind a TV.
How long does a modern WiFi router last?
The average lifespan of a quality router is 5-7 years. However, they become obsolete more quickly—after 3-4 years—as communication standards and application requirements change. In 2021, it makes sense to buy a device with more performance reserves.
