Buying a new router is always a balancing act between the desire for maximum speed and the need to stay within budget. In 2019, the networking equipment market offers a variety of solutions that are radically different from previous models. Modern standards allow gigabits of data to be transmitted over the air, but only with the right equipment.
Many users encounter problems with even an expensive device failing to penetrate walls or losing signal in distant rooms. This is often not due to a defect, but to the incorrect selection of specifications for specific operating conditions. Dual-band routers have become the new standard, displacing older single-channel models.
In this article, we'll explore what to look for when purchasing a wireless network to avoid lag and connection drops. You'll learn why the number of antennas doesn't always correlate with range and which technologies are truly useful in urban environments.
Main Wi-Fi standards and their impact on coverage
The first thing you'll encounter when studying specifications is wireless standards. In 2019, two generations are predominantly relevant: 802.11ac (Wi-Fi 5) and just emerging 802.11ax (Wi-Fi 6). Most available models support the AC standard, which operates in two frequency bands.
The good old standard 802.11n It's still found in the budget segment, but its bandwidth is no longer sufficient for streaming 4K video to multiple devices simultaneously. It only operates in the 2.4 GHz band, which is often congested by neighboring networks and household appliances.
When choosing a device, it's important to understand the difference between theoretical and actual speed. Manufacturers often list the sum of speeds for all bands, which can be misleading. The actual speed in the 5 GHz band will be significantly higher, but its range is shorter than that of 2.4 GHz.
⚠️ Please note: Equipment specifications may vary slightly depending on the board revision and delivery region. Before purchasing a specific model, please check the specifications on the manufacturer's official website or in current reviews.
What is the difference between Wi-Fi 5 and Wi-Fi 6?
Wi-Fi 6 (802.11ax) provides better performance in densely populated areas where many devices are trying to connect to the network simultaneously. It uses OFDMA technology for more efficient data transmission, reducing latency.
Frequency ranges: 2.4 GHz vs. 5 GHz
A modern home router must be dual-band. This means it can operate simultaneously in both 2.4 GHz and 5 GHz frequencies. Each has its own unique characteristics that affect signal quality in different usage scenarios.
Range 2.4 GHz It has better penetration. It bends around obstacles like walls and furniture better, providing coverage over a larger area. However, this range is highly noisy: microwaves, Bluetooth devices, and neighbors' networks operate in this range.
In turn, 5 GHz It offers clear airtime and high speeds, but it's less effective at penetrating solid walls. If your router is in one room and you're in another behind two concrete partitions, the 5 GHz signal may be unstable.
- 📡 2.4 GHz: Long range coverage, wall penetration, but low speed and a lot of interference.
- 🚀 5 GHz: High speed, no interference, but shorter range.
- 🔄 Smart Connect: Technology for combining networks into one with automatic selection of the best frequency.
Antenna design: external or internal?
There's a persistent myth that the number and size of external antennas directly determines signal strength. In fact, antenna gain is only one parameter. Internal antennas in modern models often perform just as well as external ones if the device is designed properly.
External antennas can usually be replaced or pointed in the desired direction, which allows for flexibility in setup. Gain (dBi) indicates how well the antenna focuses the signal. A high factor narrows the beam pattern, turning the signal into a "pancake," which can be detrimental for multi-story buildings.
Models with internal antennas are more aesthetically pleasing and take up less space. Manufacturers use complex antenna layouts inside the housing to provide omnidirectional coverage. For a typical apartment, this option is often preferable.
⚠️ Caution: Replacing the standard antennas with more powerful ones may cause the router's radio module to overheat and fail, as the transmitter's power is designed for a specific resistance.
MU-MIMO and Beamforming technologies
Advanced data transmission technologies are critical for ensuring a good signal in a home where multiple people are using the internet simultaneously. Without them, the router is forced to switch between clients very quickly, creating the illusion of simultaneous operation.
Technology Beamforming Beamforming allows the router to detect the location of a connected device and direct the signal precisely to that point, instead of broadcasting it uniformly in all directions. This significantly improves connection stability.
Protocol MU-MIMO (Multi-User Multiple-Input Multiple-Output) allows data to be transmitted to multiple devices simultaneously, rather than sequentially. This is especially important for families where one person watches TV, another plays games, and a third downloads files.
| Technology | Operating principle | Effect on the user |
|---|---|---|
| Beamforming | Focusing the signal on the client | Increased range and stability |
| MU-MIMO | Simultaneous data transmission | No queues during load |
| Smart Connect | Auto-frequency switching | Optimal speed without manual adjustment |
Processor and RAM: Hidden Parameters
Few people pay attention to the hardware inside a router, but they shouldn't. A weak processor and limited RAM become bottlenecks under heavy load. The device may simply not be able to handle the data streams, even with a powerful radio module.
In 2019, the minimum requirement for a home computer is a dual-core processor with a frequency of at least 800 MHz and RAM of at least 128 MB. Budget models often have 64 MB of memory, which can lead to reboots when connecting more than 10-15 devices.
If you plan to use your router for torrents, VPN servers, or installing third-party firmware, resource requirements increase exponentially. Multitasking directly depends on the computing power of the CPU.
☑️ Criteria for choosing a high-performance router
Correct installation and signal configuration
Even the most expensive router will perform poorly if placed incorrectly. The device's physical location in the apartment plays a key role in determining coverage. The center of the apartment is ideal, but often inaccessible due to a lack of outlets.
Avoid placing the router near metal objects, mirrors, aquariums, and microwave ovens. These objects can shield or distort radio waves. Also, avoid hiding the router in a closed (low-current) panel or behind a TV.
To set a channel in the 2.4 GHz band, use mobile Wi-Fi analyzer apps. Select the channel (1, 6, or 11) that is least occupied by neighbors. In the 5 GHz band, channels can be chosen freely, as they don't overlap.
⚠️ Note: Router settings interfaces may differ from manufacturer to manufacturer. General principles (channel selection, power) remain the same, but menu layout may change in new firmware versions.
Comparison of popular models of 2019
The market offers a wide range of options, from budget to premium. Entry-level models are suitable for one-bedroom apartments, while larger spaces require systems with mesh technology or powerful standalone units.
In the segment up to 3000 rubles, the models from are leading TP-Link And Tenda with AC1200 support. They provide basic comfort for watching videos and surfing. More expensive solutions from Asus And Keenetic offer advanced functionality and stability.
When choosing, consider the availability of Gigabit Ethernet ports. If your ISP offers speeds above 100 Mbps, but your router only has Fast Ethernet ports (100 Mbps), you'll be overpaying for unused Wi-Fi speed, as network access will be limited.
Should you buy a Wi-Fi 6 router in 2019?
In 2019, Wi-Fi 6 (802.11ax) is just beginning to appear in mainstream devices. Buying such a router makes sense if you already have compatible smartphones and laptops, or if you plan to use the device for 5-7 years without replacing it. For most users, Wi-Fi 5 (AC) is still more than sufficient.
Can a router itself increase internet speed?
A router can't increase speeds beyond those provided by your ISP. However, it can eliminate speed losses caused by a weak signal, channel congestion, or limited device resources. If your old router was throttling your speed, a new one will correct the situation.
What to do if the signal doesn't penetrate thick walls?
In this case, a repeater or mesh system can help. A repeater simply copies the signal, cutting the speed in half. Mesh systems create a single, seamless network with multiple access points, which is a more modern and efficient solution for larger apartments.
