Choosing a router in today's climate isn't just about buying a box with antennas; it's an investment in the stability of your entire digital home. In 2021, network bandwidth requirements have increased dramatically: simultaneous work from home, 4K streaming on multiple screens, and the active use of smart devices are placing significant strain on equipment. Incorrectly selected router may become a bottleneck, negating the high speed of the tariff provided by the provider.
This year's networking equipment market offers a wide range of solutions, from budget entry-level models to advanced gaming stations supporting the latest communication standards. Wi-Fi 6 (802.11ax) has ceased to be a rarity and has become the de facto standard for mid- and high-end devices. Understanding exactly what features you need will help you avoid overpaying for unnecessary functionality or, conversely, skimping where it's crucial.
In this article, we'll explore key selection criteria, compare popular models, and answer the questions users most frequently have when upgrading their home network. A competent approach When choosing equipment, you will forget about "dropping" internet and areas without a signal in distant rooms.
Key Wi-Fi standards and frequency bands
The first thing a buyer encounters is the abbreviations for wireless communication standards. In 2021, three main generations are relevant: Wi-Fi 4 (802.11n), Wi-Fi 5 (802.11ac) And Wi-Fi 6 (802.11ax)Buying an 802.11n router today only makes sense as a temporary solution or for very specific tasks where speed isn't a priority. Wi-Fi 5 has become the standard, delivering decent speeds, but Wi-Fi 6 is already rapidly gaining market share, offering better performance in noisy environments.
The second critical parameter is band support. Single-band routers (2.4 GHz) are becoming a thing of the past, giving way to dual-band models. 2.4 GHz has good penetration ability, but is heavily overloaded with neighboring networks and household appliances. The range 5 GHz It provides high speeds and is less susceptible to interference, but has poorer wall penetration. The ideal router for an apartment should work reliably in both bands.
⚠️ Note: Some providers still provide subscribers with outdated modems that only support 2.4 GHz. If your provider doesn't offer equipment that supports 5 GHz, it might be worth purchasing your own router and setting your provider's modem to bridge mode.
Technology OFDMA (Orthogonal Frequency-Division Multiple Access), implemented in the Wi-Fi 6 standard, allows a router to transmit data to multiple devices simultaneously within a single channel, rather than sequentially. This significantly reduces latency (ping) in games and video calls, which is especially important for apartment buildings where the airwaves are congested with signals.
Specifications: Processor, Memory, and Ports
The router's performance is determined not only by the antenna, but also by the hardware inside the case. Processor (CPU) The router's speed and RAM determine how many devices it can simultaneously handle without sacrificing speed. Budget models often have a weak single-core processor, which can choke when downloading large files and simultaneously watching videos on a smartphone.
Please note the availability of ports Gigabit EthernetIf the WAN port (for the provider's cable input) or LAN ports (for connecting PCs and consoles) have a speed limited to 100 Mbps, then plans above 100 Mbps will not work. In 2021, gigabit speeds are becoming the standard for apartments, so 10/100/1000 Mbps ports are a mandatory requirement.
It's also worth considering the amount of built-in memory for storing settings and logs, although this is less critical for the average user. More important is the ability to install third-party firmware, such as OpenWrt or Keenetic, which can significantly expand the device's functionality by adding secure tunneling capabilities or flexible queue configuration.
Layout features: area and wall material
The apartment's size dictates the requirements for transmitter power and the number of antennas. For a one-bedroom apartment or studio, even an inexpensive router with two antennas is often sufficient with a power of 2-3 dBm. However, for two- and three-bedroom apartments, the signal must penetrate load-bearing walls, which may be made of reinforced concrete, which significantly attenuates radio waves.
In such cases, it is not so much the signal strength that comes to the fore, but rather the Mesh technology. Mesh systems Mesh routers consist of multiple modules that connect to form a seamless network. Unlike traditional repeaters, which halve speed, mesh routers intelligently redistribute traffic, ensuring a stable connection from room to room.
If purchasing a mesh system with multiple modules seems excessive, consider routers with high-gain external antennas or the ability to connect additional access points via cable or PowerLine. It's important to properly position the central router: ideally in the center of the apartment and at a height to ensure uniform signal distribution.
⚠️ Caution: Placing the router inside a low-voltage electrical box, behind a TV, or on the floor is strongly discouraged. Metal structures and household appliances create a shielding effect, dramatically reducing signal quality.
Why are repeaters worse than mesh systems?
A conventional repeater receives a signal, decodes it, and transmits it further, which takes time and channel resources. As a result, the actual speed of a device connected to the repeater drops by a factor of two or more. Mesh systems use dedicated communication channels or smart switching, minimizing speed loss.
Comparison of popular router models of 2021
The market offers a wide selection of devices from various manufacturers. The segment leaders traditionally remain Keenetic, TP-Link, Asus And MikroTikEach has its own advantages: Keenetic is renowned for its operating system and stability, TP-Link offers the best value for money, Asus focuses on gaming functionality, and MikroTik offers flexible settings for professionals.
For most users, mid-range models with dual-band connectivity and gigabit ports are the optimal choice. Flagship models with Wi-Fi 6E (6 GHz) support are still overkill for a typical apartment in 2021, as few client devices support this standard.
Below is a comparison table of popular models available on the market in 2021 that have proven themselves to be reliable solutions for the home.
| Model | Wi-Fi standard | Port speed | Peculiarities |
|---|---|---|---|

Home network security
A modern router is your home network's first line of defense against external threats. In 2021, the standard for encryption became WPA3, which replaced the vulnerable WPA2. While WPA2 is still secure when using a complex password, WPA3 support is a good indicator of a device's current state.
An important feature is the ability to create a guest network. This allows you to isolate guest devices from your main network, which may contain computers with important data or smart cameras. It's also worth considering the presence of built-in antivirus solutions, such as Trend Micro or Dr.Web, which are often integrated into ASUS and Keenetic routers.
Regular firmware updates are another critical security aspect. Manufacturers periodically release patches to fix vulnerabilities. A good router should have an automatic update feature or at least a convenient notification about the release of a new firmware version via a mobile app.
⚠️ Warning: Never use the factory password to access the router's web interface (admin/admin). This is the first thing attackers change when attempting to hack your network.
Setup and Management: Apps vs. Web Interface
The era of complex web interfaces with multiple tabs is gradually fading, giving way to user-friendly mobile apps. For most users, setting up a router via a smartphone is more familiar and faster. Apps from TP-Link Tether, Asus Router or Keenetic allow you to quickly change your password, set up a guest network, or check your internet speed.
However, for advanced users, a fully functional web interface remains essential. A browser allows you to configure static routes, port forwarding for gaming servers or video surveillance, and set up a VPN client for secure internet access across all devices.
☑️ Checklist for buying a router
Ease of use also depends on the responsiveness of the interface. Cheap routers can take a long time to respond to requests when changing settings, while high-quality models respond instantly. This is especially important if you plan to frequently change settings or monitor the network status.
Frequently Asked Questions (FAQ)
Should I buy a Wi-Fi 6 router if I have older devices?
Yes, it makes sense. Wi-Fi 6 routers are backward compatible with older devices. Moreover, they manage traffic more efficiently, so even older devices can perform more reliably on a Wi-Fi 6 network, especially if there are many neighboring networks nearby.
Can a router increase internet speed beyond what my provider charges?
No, a router can't create speed out of nothing. It merely distributes the bandwidth provided by your ISP. If your plan is 100 Mbps, a router won't boost your speed to 500 Mbps, but it can provide stable transmission of those 100 Mbps over Wi-Fi, something an older router couldn't do.
How often should I reboot my router?
Modern models don't require daily reboots. If the router is operating reliably, there's no need to touch it. However, if you experience any issues, rebooting the device once a week or month is sufficient. Frequent reboots may indicate overheating or firmware issues.
Does the number of antennas affect Wi-Fi speed?
Not directly. The number of antennas affects MIMO (Multiple Input Multiple Output) technology, which allows for the transmission of more data simultaneously. However, four antennas on a cheap router won't provide any speed boost compared to two antennas on a high-quality model. The internal hardware and Wi-Fi standard are more important.
Is it worth getting a router with a USB port?
It depends on your plans. If you plan to connect an external hard drive to create a home media server (DLNA) or use a 3G/4G modem as a backup connection, then a USB port is essential. Otherwise, you can save money and get a model without one.
