Choosing network equipment has evolved from a simple shopping trip into a veritable quest, requiring an understanding of numerous technical nuances. The market is oversaturated with models marketed as new, but in reality, rebranded versions of last year's offerings with minimal changes. To avoid being entangled in marketing gimmicks and truly achieve a stable connection, it's essential to clearly understand the difference between data transmission standards and the actual needs of your home.
The situation in 2020 dictates new rules: while a simple device for distributing internet to a smartphone or laptop was once sufficient, network load has now increased exponentially. Smart kettles, CCTV cameras, 4K TVs, and simultaneous work from home demands significant bandwidth. Therefore, choosing the right router is becoming critical for the comfort of the whole family.
In this article, we'll cover the key features you should consider right now and compare popular models so you can make an informed decision. We won't delve into complex technical specifications unnecessarily, but rather focus on what truly impacts signal speed and stability in real-world conditions.
Key Wi-Fi Standards: AC vs. AX
The first thing you'll encounter when studying specifications is the designation of wireless communication standards. For a long time, the dominant standard was Wi-Fi 5 (802.11ac), which is still relevant for most apartments and provides excellent speed. However, in 2020, a new standard was finally established. Wi-Fi 6 (802.11ax), which offers not just a speed boost, but a completely different approach to traffic processing.
The main difference of the new generation is OFDMA technology, which allows the router to communicate with multiple devices simultaneously, rather than switching between them at breakneck speed. This reduces latency (ping) and prevents the network from becoming swamped when someone is watching YouTube in 4K while another user is playing an online shooter. If you have multiple devices, support Wi-Fi 6 becomes not just a nice bonus, but a necessity.
⚠️ Note: For Wi-Fi 6 to work, your client devices (smartphones, laptops) must also support this standard. If your devices are more than 2-3 years old, they will operate in compatibility mode, and you won't fully benefit from the new router.
Nevertheless, purchasing a router with ample performance is a smart strategy. Even if you don't currently have devices that support the latest protocol, that will change in a year or two, and you won't have to upgrade your equipment again. Older AC-standard models will still work, but their potential is already limited.
Frequency ranges and dual-band routers
A modern router must be dual-band, that is, it must operate simultaneously in both ranges. 2.4 GHz And 5 GHzThis is no longer an option, but a basic requirement. The 2.4 GHz band has excellent wall penetration, but it's heavily polluted by neighboring networks, Bluetooth devices, and microwaves, often resulting in slower speeds.
The 5 GHz band offers significantly higher data transfer rates and is virtually interference-free in apartment buildings. However, it has a physical limitation: it's less able to penetrate obstacles. Therefore, the ideal solution is to have both bands, which the router can intelligently distribute among devices.
When choosing a model, pay attention to the availability of technology MU-MIMOIt allows the router to transmit data to multiple devices simultaneously, rather than sequentially. In an apartment with a smart TV, a gaming console, and several smartphones running simultaneously, this feature significantly improves network response.
Some manufacturers are implementing the function Smart Connect or "Smart Switching," which automatically switches the device to a clearer frequency. This is convenient, but sometimes it doesn't work correctly, causing the device to latch onto a weak 5 GHz signal instead of a stable 2.4 GHz. A good router should allow you to flexibly configure these settings.
Performance: processor and memory size
A router is a fully-fledged computer, but with specialized tasks. It contains a processor (CPU) and random-access memory (RAM). A weak processor simply won't be able to handle encrypted traffic at high speeds, and your gigabit internet connection will hit a ceiling of 100-200 Mbps, regardless of your ISP plan.
For comfortable work in 2020, we recommend choosing models with a processor frequency of at least 800-1000 MHz per core, or better yet, dual-core solutions with a frequency of 1.2 GHz or higher. RAM also plays a role: 128 MB is the absolute minimum; 256 MB or more will be more comfortable, especially if you plan to connect USB drives to set up a file server.
Why does a router need so much memory?
The router stores routing tables, DNS cache, and temporary buffering files in memory. With a large number of connected devices (IoT devices, phones, TVs), the connection table grows, and if the RAM is insufficient, the device begins to reboot or drop connections.
Pay special attention to the cooling system. Powerful processors generate heat, and if the router lacks heat sinks or has a poorly designed one, the device may throttle (reduce frequency) or freeze under load. A metal case or the presence of ventilation holes is a good sign.
Ports and peripheral connections
The router's interface is often overlooked, and users only remember about it when it's too late. The basic set today is ports. Gigabit Ethernet (1000 Mbps)Buying a router with Fast Ethernet ports (100 Mbps) in 2020 only makes sense if your data plan is strictly limited to 50-80 Mbps and you don't plan to upgrade.
USB ports are becoming increasingly important. USB 3.0 allows you to connect an external hard drive and set up a network attached storage (NAS) or media server. However, not all routers handle files quickly: copy speeds can be slow due to processor or software limitations.
It is also worth checking the presence of the button WPS for quickly connecting devices, although it's best to disable it for security reasons. Having a separate button to turn Wi-Fi on/off or the guest network function also adds convenience in everyday use.
Comparison of popular models of 2020
To make your choice easier, we've selected several iconic models that have proven themselves on the market. The table below shows their key features for comparison.
| Model | Wi-Fi standard | LAN ports | Peculiarities |
|---|---|---|---|
| Keenetic Peak | AC2600 | 5 x Gigabit | Excellent firmware, USB 3.0, modularity |
| TP-Link Archer AX50 | AX3000 (Wi-Fi 6) | 4 x Gigabit | Accessible Wi-Fi 6, OneMesh |
| Xiaomi Mi Router 4A | AC1200 | 2 x 100 Mbps | Budget, only for plans up to 100 Mbps |
| ASUS RT-AX56U | AX1800 (Wi-Fi 6) | 4 x Gigabit | Gaming features, AiMesh, long-term support |
Models from Keenetic The firmware traditionally offers a wide range of functionality, allowing you to configure almost everything, from a VPN server to traffic prioritization. TP-Link And ASUS rely on modern standards and convenient mobile applications for management. Xiaomi remains the king of the budget segment, but requires careful selection of a specific version to avoid getting cut-down ports.
Mesh systems: is it worth the switch?
If you live in a large house or apartment with a complex layout, where one router cannot cover all the rooms with a signal, then Mesh systemsIt's a set of several modules that connect to form a seamless network. Unlike traditional repeaters (amplifiers), Mesh doesn't create a separate network with a different name, but allows devices to switch between modules without losing connection.
In 2020, many manufacturers began implementing mesh technology support in standard routers. This means you can buy one powerful router now, and a year later, add a second identical (or compatible) module and combine them into a single system. This flexible approach allows you to scale your network as needed.
☑️ Do you need a Mesh system?
However, for a standard two-room apartment, one modern router with good antennas is usually quite sufficient. Paying extra for a set of two or three modules in this case doesn't make sense, unless you want to have some extra power for the future.
Security and software
A router is the gateway between your home and the global internet, so security concerns are paramount. Outdated software can contain vulnerabilities that allow attackers to access your data or exploit your network for attacks.
When choosing a router, pay attention to the manufacturer's reputation for support. Companies like ASUS, Keenetic And TP-Link Security updates are regularly released, even for older models. Chinese no-name brands often abandon their devices immediately after sale, leaving them vulnerable.
⚠️ Important: Immediately after purchasing and setting up your router, be sure to check for firmware updates in the admin menu. The factory firmware version may be several months old and contain known security vulnerabilities.
Also an important element is the support of modern encryption protocols such as WPA3While WPA2 is still considered secure, the new standard provides better password protection against brute-force attacks. Make sure your router supports this protocol and your devices are able to work with it.
Frequently Asked Questions (FAQ)
Can I use my old router as an access point?
Yes, this is possible. To do this, connect the old router to the new one with a cable (to the LAN port, not the WAN port) and disable the DHCP server on the new router. However, the speed will be limited by the capabilities of the old device, especially if it has 100 Mbps ports.
Does the number of antennas affect Wi-Fi speed?
Not directly. Four antennas don't mean four times the speed. Antennas are needed for multiple-input-output (MIMO) and multi-band operation. The presence of signal amplifiers (FEM) inside the case is more important than the number of external antennas.
Do I need to reboot my router every day?
Modern devices don't require daily reboots. If your router is functioning reliably, there's no need to do so. However, if it's starting to glitch or lose network connectivity, rebooting it once a week can be a useful preventative measure, but this is more of a symptom of a problem than a normal one.
Where is the best place to place a router?
The ideal location is in the center of the apartment, high up, away from metal objects, mirrors, and a running microwave. Placing the router in a closet niche or behind a TV significantly reduces signal quality.
