Choosing a router these days isn't just about buying a box with antennas; it's an investment in the comfort of your entire family's digital life. The networking equipment market is oversaturated with models, and without a clear understanding of the technical nuances, it's easy to get lost in marketing gimmicks. Choosing the right router router It can solve problems with connection interruptions in distant rooms and ensure high speed even when dozens of gadgets are connected simultaneously.
In 2021, home network requirements have increased significantly compared to previous periods. While a basic model was once sufficient for checking emails, now 4K video streaming, lag-free online gaming, and remote work require significant bandwidth. In this article, we'll explore which parameters to prioritize to avoid overpaying for unnecessary features and also avoid sacrificing critical stability.
Mistakes in selection often lead to users blaming the provider for poor internet service, although the problem lies in the equipment's inability to handle the load. Wi-Fi router The router is the heart of your home network, and its health directly impacts data transfer quality. Let's look at the key criteria to help you make an informed decision.
Wireless Standards: Why WiFi 6 Matters in 2021
The first thing a customer encounters in a store or on a marketplace is the abbreviations of communication standards. For a long time, it was dominant 802.11ac (known as Wi-Fi 5), which is still relevant for the budget segment. However, in 2021, the de facto standard for new equipment is becoming 802.11ax, or Wi-Fi 6This standard not only increases maximum speed, but also fundamentally changes the way we work with multiple connected devices.
The main feature of Wi-Fi 6 is the technology MU-MIMO and OFDMA, which allow the router to communicate with devices simultaneously rather than one at a time. If you have a smart home system, multiple smartphones, laptops, and TVs in your apartment, an older router will create a queue of requests, causing lag. Newer models efficiently distribute traffic, reducing latency even during peak hours.
Is Wi-Fi 6 worth the extra cost? If you live alone and only use the internet for social media, perhaps not. But for a modern family where kids play online games and parents work via video conferences, it's a necessary condition for network stabilityFurthermore, new smartphones and laptops from 2020-2021 are already equipped with modules that support this standard, which means they will only unlock their full potential with the appropriate router.
- 🚀 Speed: The theoretical throughput of Wi-Fi 6 is 30-40% higher than its predecessor.
- 📱 Density: Ideal operation in the noisy airwaves of apartment buildings.
- 🔋 Energy efficiency: The TWT function allows IoT devices to operate longer on battery power.
It's important to keep in mind that to achieve high speeds, not only the router but also the receiving device (client) must support the appropriate standard. If you buy a top-of-the-line router with Wi-Fi 6 but connect a 2015 laptop to it, the connection will be established at the maximum supported by the laptop. However, buying equipment with a reserve for the future is a smart strategy, as replacing a router is less common than upgrading a smartphone.
Frequency bands: the battle between 2.4 GHz and 5 GHz
A modern router for an apartment must be dual-bandThis means support for two frequency bands: 2.4 GHz and 5 GHz. The 2.4 GHz band is the "old guard," offering good wall penetration but low speed and significant noise pollution from neighboring networks and household appliances like microwaves.
Range 5 GHz It provides high data transfer rates and is virtually interference-free in apartment buildings. However, it has a physical drawback: it penetrates structural walls less effectively and attenuates more quickly over distance. Therefore, having both bands in a single device is the optimal solution for covering the entire apartment.
⚠️ Note: Some budget models may be labeled "AC1200" but only support 5 GHz on one antenna or at limited speeds. Always check the specifications: number of antennas and technology support
2x2 MIMOor3x3 MIMOin the 5 GHz range.
Most modern routers support the function Smart Connect (or similar names for different brands). It combines both frequencies into one network with a common name, and the router itself decides which frequency to connect your device to. This is convenient for guests, but sometimes the algorithm can make mistakes, connecting a phone near the router to the slow 2.4 GHz band. In such cases, experienced users prefer to separate the networks, giving them different names, for example, Home_24 And Home_5G.
High-speed ports and WAN connection type
The appearance of the ports on the back of a router is often overlooked, but in vain. If your ISP plan offers 500 Mbps or 1 Gbps speeds, but the ports on the router are labeled Fast Ethernet (100 Mbps), you won't physically get more than 90-95 Mbps. In 2021, ports should become the standard for any new router. Gigabit Ethernet (10/100/1000 Mbps).
It's also worth noting the presence of a USB port. It can be useful for connecting a 3G/4G modem as a backup connection or for setting up simple file storage (NAS) by connecting an external hard drive. However, if you need high-speed file access over the network, the built-in USB 2.0 port in budget routers may be a bottleneck.
There are also models with a WAN port supporting speeds above 1 Gbps (e.g., 2.5 Gbps). This is especially true for plans above 1 Gbps, which are still rare but are becoming more affordable in large cities. For most users, a gigabit WAN and LAN port will be more than sufficient.
| Port type | Maximum speed | For which tariffs | Designation |
|---|---|---|---|
| Fast Ethernet | up to 100 Mbit/s | Up to 50-80 Mbps | 10/100 Mbps |
| Gigabit Ethernet | up to 1000 Mbit/s | Up to 500-900 Mbps | 10/100/1000 Mbps |
| Multi-Gig (2.5G) | up to 2500 Mbps | Above 1 Gbps | 2.5 GbE |
Check what type of connector your provider uses. In most apartments, this is RJ-45 (Ethernet), but in some older houses or specific tariffs it may be used GPON (direct fiber). GPON usually requires a specific terminal from the provider, and a regular router connects to it.
Signal coverage and apartment layout
The apartment's size and wall materials are critical factors. A 30-square-meter studio is one thing, while a three-bedroom apartment with load-bearing concrete walls is quite another. The number of antennas isn't always directly proportional to the range, but their presence and gain (measured in dBi) do play a role. Antennas with 5 dBi gain are generally the standard.
If the router is located in a metal enclosure in the hallway or behind the TV, the signal will be shielded. The ideal location is the center of the apartment, on a hill, in an open space. In 2021, the following are relevant for large areas: Mesh systemsIt's a set of several modules that create a single, seamless network. As you walk around your apartment, your phone automatically switches to the nearest access point without losing the connection.
What is the difference between a router and a mesh system?
A standard router distributes Wi-Fi from a single point. A mesh system consists of several modules (one main module, the others satellites) that together cover a large area with a single network name. This is more expensive, but more effective for houses and large apartments.
For a standard two-bedroom apartment, one powerful router with three external antennas is often sufficient. If the signal is present but weak in the far room, a repeater can be used, although this solution often cuts the speed in half. It's better to consider purchasing a router that supports wireless technology. Beamforming, which focuses the signal towards the connected device, rather than dispersing it evenly in all directions.
⚠️ Warning: Don't rely on "magic" stickers or foil to boost your signal. These are myths. If there's no signal, the only solution is to move your router, upgrade to a more powerful model, or install an additional access point.
Processor and RAM: Hidden Parameters
A router is a fully-fledged computer that runs 24/7. It has its own processor (CPU) and random-access memory (RAM). Cheap models often overheat and freeze when downloading torrents or actively loading internet channels, as their processor can't handle the data flow (NAT table).
For comfortable work in 2021, it is desirable to have at least a dual-core processor with
