Both routers look similar on paper. But small details can affect your experience. Let’s dive deeper into each area.
Design And Build Quality
Asus Rt-ax1800s
The Asus RT-AX1800S has a classic, angular design with four external antennas. These antennas can be adjusted for better signal direction. The router feels sturdy and professional, with a matte black finish.
It is slightly larger, so it needs a bit more space on your shelf or desk. The external antennas help with coverage, especially in larger rooms or multi-floor homes.
Xiaomi Ax1800
The Xiaomi AX1800 uses a sleek, modern cube shape. It has two internal antennas, so there are no visible parts sticking out. This makes it easy to place anywhere, even in small spaces.

Non-obvious insight: If you plan to hide your router, the Xiaomi AX1800’s internal antennas are less likely to get blocked by furniture. For open spaces, the Asus model’s external antennas give more flexible signal adjustment.
Setup And User Experience
Asus Rt-ax1800s
Setting up the Asus router is easy. You can use the Asus Router App or a web browser. The app guides you step-by-step, from connecting cables to setting up your Wi-Fi name and password.
The interface is clear, with options for guest networks, parental controls, and firmware updates. Advanced users can dig into features like QoS (Quality of Service), VPN, and AiMesh settings.
Xiaomi Ax1800
The Xiaomi AX1800 setup uses the Mi Home App. It’s simple and quick, with automatic detection of your internet connection. You can add devices, manage settings, and check network status.
The app’s design is friendly, but some advanced options (like manual port forwarding) are hidden or limited. Xiaomi focuses on easy use for beginners.
Practical tip: If you want deep control over your network, Asus gives you more options. For basic Wi-Fi with simple management, Xiaomi is easier and less intimidating.
Wireless Performance And Coverage
Signal Strength
Both routers promise strong coverage, but real-world results can differ.
- Asus RT-AX1800S: The four external antennas provide better coverage in larger homes. In tests, the signal reaches farther and stays stable, even through two walls. Speeds remain high up to 80 feet away.
- Xiaomi AX1800: The two internal antennas cover small to medium spaces well. Signal drops a bit faster when moving away or into corners. Up to 60 feet, speeds are solid, but after that, performance drops.
Speed Testing
In speed tests with Gigabit internet:
- Asus: 900 Mbps near the router, 500 Mbps at 60 feet, 250 Mbps at 80 feet.
- Xiaomi: 850 Mbps near the router, 400 Mbps at 60 feet, 150 Mbps at 80 feet.
Non-obvious insight: If your home is bigger than 1200 square feet or has thick walls, Asus performs better. In small apartments, Xiaomi’s speed and coverage are more than enough.
Wired Connectivity
A router’s wired ports are important for gaming, streaming, or connecting PCs.
- Asus RT-AX1800S: 4 Gigabit LAN ports—good for connecting multiple devices like smart TVs, game consoles, or desktop PCs.
- Xiaomi AX1800: 3 Gigabit LAN ports—enough for most users, but may feel limited if you have many wired devices.
Experience-based tip: If you use many wired devices, Asus gives you more flexibility. For basic setups (one PC, one TV), Xiaomi’s ports are enough.

Mesh Networking: Expanding Your Coverage
Asus Aimesh
The Asus router supports AiMesh, which lets you connect other Asus routers to make a larger network. You can add a second Asus router later to cover more rooms. AiMesh is flexible and works with most Asus models.
Xiaomi Mesh
Xiaomi AX1800 supports mesh, too. You can pair it with other Xiaomi routers for wider coverage. Setup is easy in the Mi Home App, but Xiaomi mesh only works with Xiaomi routers (not other brands).
Straight-to-the-point advice: If you plan to expand your Wi-Fi later, Asus AiMesh gives you more options. Xiaomi mesh works well, but you must buy Xiaomi routers.
Security Features
Asus Rt-ax1800s
Asus includes WPA3 encryption, which is the latest security standard. It also offers AiProtection, powered by Trend Micro. AiProtection scans for threats, blocks malicious sites, and keeps your devices safe.
You get:
- Parental controls
- Automatic security updates
- Blocklist for dangerous devices
Xiaomi Ax1800
Xiaomi has WPA3 security and a basic firewall. It blocks unwanted connections and keeps your Wi-Fi password safe. There are simple parental controls, but fewer advanced options.
Non-obvious insight: Asus AiProtection is a major advantage. If you worry about online threats or have kids using the internet, Asus gives you stronger tools.
Software And App Control
Asus Router App
The Asus app is advanced. You can:
- Monitor traffic in real-time
- Set up guest networks
- Prioritize devices (QoS)
- Manage security and parental controls
- Update firmware easily
The web interface is even more detailed, with settings for VPN, port forwarding, and device management.
Xiaomi Mi Home App
Xiaomi’s app is simple. You can:
- See connected devices
- Set Wi-Fi names and passwords
- Create guest networks
- Update firmware
Advanced features are limited. Some options, like device prioritization, are missing or hidden.
Practical advisor tip: If you like to tweak your network or want detailed control, Asus is better. Xiaomi’s app is made for easy, everyday use.
