The problem of "dead zones" in an apartment or office is familiar to many equipment owners. ASUSHaving the connection reach its maximum speed in one room but then drop out behind a wall is often frustrating and time-consuming. Fortunately, in most cases, coverage can be dramatically improved using software or simply by rearranging the equipment.
Before rushing out to buy expensive new equipment, it's worth conducting a thorough diagnosis of your current network. Interference from neighboring routers, household appliances or even aquariums can significantly reduce range your device. Understanding the physics of radio wave propagation will help you set it up correctly. router without unnecessary costs.
In this article, we'll explore all available methods for expanding your coverage area, from basic transmitter setup to creating a complex mesh system. You'll learn how to select the right channels, adjust signal strength, and use additional devices to create a seamless space.
Analysis of the current coating and selection of installation location
The first step to a stable internet should be proper localization ASUS routerMany users hide their equipment in niches, cabinets, or behind televisions, which significantly reduces the antenna's effectiveness. The signal must propagate freely, without encountering any shielding obstacles.
The optimal location is considered to be the center of the apartment, 1.5–2 meters above the floor. If the router is located in a corner, half the signal will be lost to neighbors or the street, which is ineffective. It's also important to consider the wall material: concrete with rebar blocks the signal more than drywall or wood.
⚠️ Caution: Placing your router near microwave ovens, baby monitors, or Bluetooth speakers may cause constant connection interruptions due to operation in the same frequency range.
To accurately identify problem areas, use specialized utilities on your smartphone, for example WiFi AnalyzerWalk around your apartment and see where the signal level drops. -75 dBmIt is in these areas that the coating will need to be reinforced.
Optimizing settings via the ASUS web interface
Modern routers ASUS run on an operating system ASUSWRT or Asuswrt-Merlin, which provide advanced radio module control capabilities. To access the control panel, enter the address in your browser 192.168.1.1 or follow the link router.asus.com.
In the section Wireless network (Wireless) find the parameter Transmitter power (Tx Power). By default, it's often set to "Auto" or medium. Switching to the maximum level ("100%" or "High") can increase the range by 15-20%, which is sometimes critical for distant rooms.
The choice of channel width is equally important. For the 2.4 GHz band, it is recommended to use a width of 20 MHz, if the air is very noisy, or 40 MHz For maximum speed in clear air. In the 5 GHz band, it's better to leave it on auto-selection or set it to 80 MHz, but remember that the wider the channel, the less its penetration ability through walls.
Be sure to check if the feature is enabled. BeamformingThis technology allows the router to focus the signal directly on the connected client, rather than dispersing it evenly in all directions. For devices ASUS This is a standard option that significantly improves stability.
connection strength at the boundary of the coverage area.
☑️ Setting up an ASUS router
Selecting frequency range and channels
The 2.4 GHz frequency has better penetration, but suffers from congestion. In apartment buildings, dozens of neighboring networks can operate here, creating a "mess" of signals. The 5 GHz band is cleaner and faster, but its waves have a harder time penetrating solid obstacles.
To increase range in challenging environments (such as behind multiple walls), it sometimes makes sense to switch critical but slow devices (smart home devices, sensors) to 2.4 GHz. For streaming and gaming, where the device is close to the router, 5 GHz is ideal.
Use manual channel selection instead of automatic. Automatic channel selection often doesn't select the clearest channel. In the 2.4 GHz band, only channels 1, 6, and 11 are non-overlapping. Try switching between them and measuring the speed.
| Parameter | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Penetration ability | High | Medium/Low |
| Maximum range | Up to 50-70 meters | Up to 20-30 meters |
| Interference resistance | Low | High |
| Recommended channel width | 20 MHz (for range) | 40-80 MHz |
If you live in a private home, setting the correct channel becomes even more important, as the signal can come not only from neighbors but also from outdoor cameras or wireless sensors.
Using ASUS AiMesh technology
If one router is physically insufficient for the entire area, the best solution is to create a Mesh system. AiMesh allows you to connect multiple compatible routers together ASUS into a single network with one name and password.
Unlike traditional repeaters, which reduce speed by 50%, the AiMesh system intelligently distributes traffic and switches client devices between nodes without interrupting the connection. You can even use an older compatible ASUS router as an additional node.
To configure, go to the main router interface, select the section AiMesh and click "Search." The system will find available devices. Importantly, nodes can be connected either via cable (backhaul) or over the air.
⚠️ Important: When connecting nodes over the air (Wireless Backhaul), try to position the secondary router so that it receives at least 2-3 bars of signal from the primary router. Otherwise, the speed at the endpoints will be low.
AiMesh Device Compatibility
Not all older ASUS models support AiMesh nodes. It's best to check the full list of compatible models (including the RT-AC, RT-AX, RT-AC88U, and newer series) on the manufacturer's official website before purchasing additional equipment.
This solution is ideal for multi-story buildings where a single router cannot penetrate the floors. Nodes can be placed on different floors, ensuring uniform coverage throughout the entire building.
Hardware upgrades: antennas and repeaters
If software settings aren't enough, you can resort to hardware methods. Replacing the stock antennas with more powerful ones (with a gain of 5 dBi or 9 dBi) is a simple way to improve reception. However, remember: an antenna amplifies not only the transmitting signal but also the receiving signal.
If the client device (for example, an old laptop or smartphone) has a weak built-in antenna, even a powerful router won't help—the device simply won't hear the return signal. In such cases, a USB WiFi adapter for a PC can help.
Using a repeater is a budget option. Routers ASUS can operate in repeater mode. To do this, select the operating mode Repeater mode (Repeater mode). The device will connect to the main network and will rebroadcast the signal further.
When installing a repeater, it's critical to find the "golden mean": it should be close enough to the main router to receive a high-quality signal, but already in an area where the main device's coverage begins to weaken.
Comparison of network expansion methods
The choice of method depends on budget, room size, and speed requirements. The most expensive solution isn't always the only one. Sometimes, properly setting up existing equipment can deliver 80% of the results.
For small apartments, simply changing the channel and router position is often sufficient. For larger spaces and homes with thick walls, a mesh system or wired access point installation is essential.
The table below shows a comparison of the main signal enhancement methods:
| Method | Price | Efficiency | Complexity |
|---|---|---|---|
| Channel/Power Setup | 0 rub. | Average | Low |
| Replacing antennas | Low | Average | Low |
| Repeater | Average | Medium/High | Average |
| AiMesh System | High | Maximum | Average |
Frequently Asked Questions (FAQ)
Can foil or a metal can really boost a signal?
Theoretically, a metal reflector can redirect the signal in the desired direction, creating a parabolic antenna effect. However, in practice, this often leads to router overheating due to poor ventilation and uneven signal distribution. A high-gain antenna is much more effective.
Why does the speed drop when connecting through a repeater?
The repeater operates in half-duplex mode: it first receives data from the router and then transmits it to the client using the same communication channel. This automatically splits the channel's bandwidth in half. Using a wired connection (backhaul) between the nodes solves this problem.
Does updating firmware affect the range?
Yes, manufacturers frequently release updates that optimize the radio module and data transfer algorithms. Check the tab regularly. Administration → Software Update in the router interface.
Is it worth buying a router with more antennas?
The number of antennas isn't always directly proportional to the range. What's more important is the presence of MIMO (Multiple Input Multiple Output) technology and support for standards. WiFi 6 (802.11ax)Four antennas may provide better performance with multiple devices simultaneously, but won't necessarily penetrate three concrete walls better than two powerful antennas.
