Choosing a new router has become a real quest these days due to the abundance of abbreviations and numbers on the boxes. One of the most popular markings found in the mid-price segment is AX1800Many users mistakenly believe that this figure represents the internet speed they'll receive from their provider, but that's not entirely true. In fact, it represents the combined theoretical throughput of all the device's radio modules.
In this article, we will take a detailed look at what lies behind the markings. AX, why the sum of speeds doesn't equal actual performance, and who really needs this particular class of hardware. Understanding these nuances will help you avoid overpaying for features you won't need or, conversely, buying a device that's too weak for modern tasks.
Wireless technology has come a long way since the days of old routers with antennas. If you're planning to upgrade your home network, understanding the different device classes is the first and most important step before heading to the store.
Decoding the AX1800 markings
The letters and numbers on the router's body aren't just a marketing ploy, but the device's technical specifications. Let's break down the designations. AX1800 by its components to understand its physical meaning. The first part of the code indicates the generation of the Wi-Fi standard.
Designation AX complies with the standard IEEE 802.11ax, which is better known in the consumer segment as Wi-Fi 6This is a modern technology that replaces the previous generation of AC (Wi-Fi 5). The main advantages of AX include increased network efficiency with a large number of connected devices and reduced latency.
The number 1800 denotes the combined maximum data transfer rate in both frequency bands. However, it's important to understand that this isn't the speed of a single channel. Routers in this class are typically dual-band, and the speed is divided between them as follows:
- 📡 2.4 GHz band: provides speeds up to 574 Mbps.
- 🚀 5 GHz band: provides speeds up to 1201 Mbps.
- 🧮 Sum: 574 + 1201 = 1775 Mbps, which is rounded up to 1800.
This distribution allows the device to be universal. Older devices that only operate on the 2.4 GHz band will be able to connect to the network, albeit at a slower speed, while modern smartphones and laptops will use the powerful 5 GHz band to transmit heavy content.
⚠️ Please note: Actual wireless network speeds are always lower than theoretical speeds due to signal encoding losses, distance to the router, and interference. Expect to see approximately 60-70% of the stated speeds under ideal conditions.
Thus, AX1800 — is a balance between the new standard's performance and affordability. It's the gateway to the world of Wi-Fi 6, which has already become the de facto standard for new devices.
Technological advantages of Wi-Fi 6 (802.11ax)
Transition to the standard AX It's not just a matter of increasing specifications, but the introduction of fundamentally new mechanisms for working with radio signals. While previous standards primarily increased channel bandwidth, Wi-Fi 6 focuses on efficiency.
One of the key technologies is OFDMA (Orthogonal Frequency-Division Multiple Access). It allows a single data transmission channel to be divided into smaller subchannels. This allows the router to transmit data to multiple devices simultaneously within a single transmission cycle, rather than having to wait in line, as was previously necessary.
Another important feature is technology TWT (Target Wake Time). It allows devices to negotiate with the router when to turn on the radio module to receive or transmit data.
- 🔋 Smartphones and tablets sleep longer, saving battery power.
- 📉 The overall noise level on the air is reduced.
- ⏱️ Reduced latency for time-critical applications.
Also worth mentioning is modulation 1024-QAMThe AC standard used 256-QAM. Increasing coding density allows for 25% more data to be transmitted in the same frequency range. This is especially noticeable when transferring large files within a local network.
Together, these technologies make the network more stable. Even if you have a dozen gadgets at home, including smart light bulbs and TVs, an AX1800 router will handle traffic distribution much better than its predecessors.
Real speed and performance
Many users are interested in the question: "What actual speed will I get?" It's important to immediately distinguish between internet access speed (provider tariff) and local wireless network speed.
If your ISP plan is 100 Mbps, the AX1800 router won't make your internet any faster than that. However, it will ensure stability and eliminate speed drops during peak hours. If you have a 500 Mbps or 1 Gbps plan, then it's a great choice. AX1800 will reveal its potential.
In the 5 GHz band, the actual "over-the-air" speed at close range (in the same room) can reach 800-900 Mbps. This is sufficient for:
- 🎮 Online gaming without lags.
- 📺 Watch 4K HDR videos from the server.
- 💾 Fast file backup to NAS.
However, physical limitations should be considered. Walls, especially load-bearing ones with reinforcement, significantly weaken the 5 GHz signal. At a distance of 10-15 meters through two walls, the speed can drop to 200-300 Mbps, which is still an excellent result.
| Parameter | 2.4 GHz | 5 GHz |
|---|---|---|
| Max. speed | up to 574 Mbps | up to 1201 Mbps |
| Channel width | 20/40 MHz | 20/40/80 MHz |
| Permeability of walls | High | Medium/Low |
| Workload | High (many neighbors) | Low |
To fully utilize the AX1800's potential, gigabit LAN and WAN ports are recommended. If the router's ports are limited to 100 Mbps, the whole point of purchasing a modern device is lost.
Comparison with other router classes
To understand the AX1800's place in the market, let's compare it to other popular classes. This will help you decide whether this model is right for you or whether you should consider other options.
Confrontation AC1200 (Wi-Fi 5) and AX1800 (Wi-Fi 6) are the most relevant. AC1200 offers approximately 300 Mbps on 2.4 GHz and 867 Mbps on 5 GHz. The speed difference on 5 GHz is approximately 30-40% in favor of AX. Furthermore, AC1200 lacks OFDMA and TWT technologies, making it less effective in smart home applications.
On the other hand, there is a class AX3000What's the difference? The AX3000 typically supports a 160 MHz channel width in the 5 GHz band, which doubles the speed to 2400 Mbps (theoretically). The AX1800 is limited to an 80 MHz channel.
- 🐢 AX1200/AC1200: A budget option for small apartments and plans up to 100 Mbps.
- 🚀 AX1800: The golden mean for tariffs up to 500-800 Mbps and multiple devices.
- ⚡ AX3000/AX5400: The choice for geeks, 1 Gbps plan owners, and LAN enthusiasts.
Paying extra for the AX3000 makes sense if you have devices that support 160 MHz (such as flagship smartphones or laptops with Wi-Fi 6E) and frequently transfer large files within your network. For general internet content consumption, the AX1800 is more than sufficient.
Effect of 160 MHz channel width
Using a 160 MHz channel doubles the speed but reduces the number of available channels. In an apartment building, this can lead to greater interference than using 80 MHz.
Who should use an AX1800 router?
This class of devices is ideal for the modern average family. If your apartment has 3-5 people, each with a smartphone and all using the internet simultaneously, the AX1800 will provide a comfortable experience.
It's an excellent choice for those with high-speed internet plans (200 to 800 Mbps). You'll be able to fully utilize the capabilities of Fiber-to-the-Home (FTTH) without hardware bottlenecks.
It is also an optimal solution for those who are just starting to implement smart homeDozens of sensors, light bulbs, and outlets would overload older routers, causing devices to fail. Wi-Fi 6 technology handles large numbers of connections much more reliably.
⚠️ Note: If you have a very large apartment (over 80-90 sq. m) or a complex layout (many concrete walls), a single router may not be enough. In this case, it's better to consider mesh systems, which are also available in the AX1800 class.
This class is also suitable for entry-level and mid-level gamers, thanks to the reduced ping achieved with OFDMA technology. However, professional esports players should consider more expensive models with traffic prioritization and 2.5 Gbps ports.
☑️ Do you need AX1800?
Popular models and settings
There are numerous models on the market from various manufacturers, all powered by Broadcom, MediaTek, or Qualcomm chipsets. Popular brands producing AX1800-class routers include TP-Link (Archer AX20/AX21 series), Keenetic (models of the KN-1xxx series), Xiaomi (Mi Router AX1800/AX1800 Pro) and ASUS.
Setting up such devices is generally straightforward. Most modern routers support configuration via a mobile app. After connecting the provider's cable to the WAN port, the system will automatically detect the connection type.
To manually configure or check the settings, you need to log in to the web interface. This is usually done at 192.168.0.1 or 192.168.1.1In the wireless network menu, make sure that the mixed mode or forced mode is selected. 802.11ax.
It's recommended to separate network names (SSIDs) for the 2.4 and 5 GHz bands by adding the suffix "_5G" to the name. This will allow you to manually select the fast network for devices located near the router and leave the slower, but longer-range network for remote rooms.
Don't forget to update your router's firmware immediately after purchase. Manufacturers frequently release updates that improve radio module stability and patch security vulnerabilities.
Should I disable WPA3 on my AX1800 router?
WPA3 is the newest and most secure security standard. However, some older devices may not see or connect to the network if only WPA3 is enabled. In this case, it's best to select Mixed Mode in the security settings. WPA2/WPA3This will ensure compatibility with old gadgets and security for new ones.
Does the number of antennas affect the speed of the AX1800?
The number of antennas affects MIMO (Multiple Input Multiple Output) technology. AX1800 routers typically feature a 2x2 MIMO design. Having four external antennas is often a marketing ploy or a way to improve coverage, but it doesn't double the speed compared to two antennas if the internal radio circuitry remains the same.
Is it possible to connect two AX1800 routers together to create a Mesh network?
Yes, many manufacturers allow you to connect their routers into a single mesh network. However, this typically only works within a single brand and often only between specific models. Check the specifications of your specific model to see if it supports the EasyMesh protocol or proprietary meshing technology.
Why doesn't my phone show the Wi-Fi 6 icon?
The "6" or "6+" icon next to the Wi-Fi icon only appears when the device is connected to an 802.11ax network. If the phone is connected to the 2.4 GHz band or if the router is configured in legacy mode, the icon may not appear, although the connection will still work.
