Buying a new router is always a balancing act between the desire for maximum speed and the need to stick to a reasonable budget. The market is overflowing with hundreds of models, and understanding acronyms like AX, AC, MU-MIMO, and OFDMA can be more difficult than understanding the specifications of a new smartphone. However, choosing the right device can radically improve the quality of your home internet, eliminating dead zones and lag in games.
In this article, we won't simply list models; we'll examine the key criteria that truly impact connection stability in an apartment building. You'll learn why the number of antennas isn't the most important parameter, and when it's worth paying extra for a next-generation standard.
First, it's important to determine the actual needs of your network. If you only have a couple of smartphones and a laptop in your apartment accessing social media and email, your hardware requirements will be quite different. It's a completely different story if you work from home with large amounts of data, stream 4K video to a Smart TV, and simultaneously play online shooters.
Wi-Fi Standards: Why AC Is No Longer Enough
The first thing you'll encounter when looking at specifications is wireless standards. For a long time, wireless was king. Wi-Fi 5 (802.11ac), which still handles many tasks perfectly. However, in 2023, the de facto standard will become Wi-Fi 6 (802.11ax), offering not only faster speeds but also better performance across multiple connected devices.
The main advantage of the sixth generation is technology OFDMA, which allows a router to transmit data to multiple devices simultaneously within a single channel. This is critical for multi-apartment buildings, where the airwaves are clogged with neighboring signals. Older routers are forced to queue up, which causes delays, while newer models effectively fragment traffic.
⚠️ Attention: To take advantage of Wi-Fi 6, your client devices (smartphones, laptops) must also support this standard. If you have devices from 2018 or later, you won't notice a difference in speed, but your router will still operate in backward compatibility mode.
There is also an intermediate stage of development known as Wi-Fi 6E, which adds the 6 GHz band. This is a "clean highway" without interference, but it's currently only suitable for flagship smartphones and very densely populated areas. In most cases, standard Wi-Fi 6 is sufficient for a typical apartment.
Frequency ranges: 2.4 GHz vs. 5 GHz
A modern router must be dual-band. Frequency 2.4 GHz It has excellent wall penetration, but it's extremely congested. This frequency is used not only by neighbors' networks, but also by Bluetooth headsets, microwave ovens, and wireless mice. Speeds here rarely exceed 40-60 Mbps in real-world conditions.
Range 5 GHz It provides high speeds and minimal latency, but has a shorter range and is less effective at penetrating solid walls. Therefore, the ideal usage scenario would be as follows: smart home and IoT devices (lamps, sockets) are connected to the 2.4 GHz band, while laptops, consoles, and TVs are connected to the 5 GHz band.
An important function is Smart Connect (or similar names for different brands), which combines both bands into a single network with a single name. The router automatically decides which frequency to connect to based on the device's location and channel load. This eliminates the need for the user to manually switch between networks as they move around the apartment.
Connection Type and Ports: Don't Become a Bottleneck
Even the most powerful router processor won't help if the physical interface can't handle the incoming speed. In 2023, the minimum acceptable standard for all LAN and WAN ports is Gigabit Ethernet (1 Gbps)Buying a device with Fast Ethernet ports (100 Mbps) is a waste of money, as they will cut your plan above 100 Mbps.
Please note the presence of USB ports. Availability of a connector USB 3.0 Allows you to connect an external hard drive and set up a home file storage (NAS) or media server. USB 2.0 is also suitable for a print server or 3G/4G modem, but file copying speeds will be slow.
Let's compare port characteristics depending on the device class:
| Router class | WAN/LAN ports | Availability of USB | Real Wi-Fi speed |
|---|---|---|---|
| Budget | 1 Gbps | No / USB 2.0 | up to 400 Mbit/s |
| Average | 1 Gbps (all ports) | USB 3.0 | up to 600 Mbps |
| Top-of-the-line (Wi-Fi 6) | 2.5 Gbps and above | USB 3.1 / Type-C | up to 1500 Mbps+ |
| Mesh system | 1 Gbps (often 1 port) | Depends on the model | Depends on the backhaul |
It is worth mentioning separately dedicated WAN portIn some budget models, the ports aren't strictly assigned, and any of them can be designated as the internet input. This is convenient, but can sometimes lead to confusion during initial setup. In more expensive models, the ISP cable input is often color-coded.
Coverage Area and Architecture: Router or Mesh?
Choosing between a classic router and Mesh system It depends on the layout of your home. A standard router with powerful antennas will handle an apartment up to 60-70 square meters with an open floor plan just fine. It creates a single, powerful access point, the signal from which extends in all directions.
If you have a multi-room apartment with thick load-bearing walls, hallways, or an area larger than 80-90 square meters, a single device may not be enough. This is where mesh systems come into play. These are a set of several modules (the main router and satellites) that create a single, seamless network. As you walk around the apartment, your phone automatically switches to the nearest module without losing the connection.
What is the difference between a repeater and a mesh system?
A repeater (amplifier) simply copies the signal, often creating a new network with the _EXT prefix and losing up to 50% of the speed. A mesh system uses smart algorithms to select the optimal data path, maintaining a single network (SSID) and high speed across the entire coverage area.
It's important to consider the wall material. Reinforced concrete floors and walls with rebar shield the 5 GHz signal almost completely. In such cases, even a mesh system may require cabling between modules to establish a dedicated backhaul, turning the wireless network into a wired one with access points.
⚠️ Attention: The flooring specifications listed on the box (e.g., "up to 120 m²") are often idealized and based on an open, unwalled space. Always allow a 30% discount for the actual floor plan.
Performance and hardware: processor and memory
A router is a fully-fledged computer, albeit a specialized one. It has its own processor (CPU), random-access memory (RAM), and flash storage. Multi-core processor This is necessary if you plan to download torrents directly to your router, use VPN tunnels, or connect dozens of smart devices.
The amount of RAM affects stability when there are a large number of simultaneous connections. If there is insufficient memory, the NAT table becomes full, and new devices cannot access the internet until older devices free up resources. For home use in 2023, this is considered the norm. 256 MB RAM, and for advanced scenarios - 512 MB and above.
It's also worth paying attention to the cooling system. High-powered models often run hot. The lack of heatsinks or ventilation holes can lead to throttling (reduced performance) or reboots under load. Touch the device's case in the store: if it's already warm on display, imagine what it will be like under load in the summer.
☑️ What to look for in the specifications
Software and Security
Hardware is only half the battle. The other half is firmware. Leading manufacturers like Keenetic, Asus, TP-Link, regularly release security updates. Outdated software is a vulnerability through which attackers can gain access to your network or use your internet to attack other servers.
Modern routers offer convenient mobile apps for configuration. These apps make it easy to provide guest access, limit internet time for children, or prioritize traffic for gaming (QoS). Flexible configuration options QoS (Quality of Service) It's critical if someone in your household starts downloading a 100GB game while you're trying to hold a video conference.
Don't ignore built-in security features either. Many models now come with a license for antivirus databases (for example, from Dr.Web or Trend Micro) or have built-in DNS filters to block fraudulent websites. This is a basic level of hygiene that should be enabled by default.
Frequently Asked Questions (FAQ)
Should I buy a router with Wi-Fi 6E support?
For most users in 2023, this is overkill. Wi-Fi 6E operates in the 6 GHz band, which is currently only supported by flagship smartphones and laptops. Furthermore, the 6 GHz signal penetrates walls even worse than 5 GHz. Paying extra is only worth it if you live in a very densely populated area with many neighbors clogging the airwaves.
Can I use my old router as an access point?
Yes, this is a great idea for extending coverage. You need to connect the old and new routers with a cable and set the old one to "Access Point" mode. In this mode, it disables its IP address distribution (DHCP) and simply broadcasts Wi-Fi, expanding the coverage area of your primary network.
Does the number of antennas affect speed?
Not directly. Four protruding antennas don't guarantee a better signal than two. MIMO (Multiple Input Multiple Output) technology and transmitter power are more important. Antennas are often hidden inside the router's case, but they perform more efficiently than cheaper external alternatives. The number of antennas often correlates with the number of data streams, but not with range.
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). Never hide the router in a niche, behind a TV, or in a metal enclosure. Metal and mirrors shield the signal, and a confined space will cause the device to overheat.
