Performance And Speed
One of the most important things for any router is real-world speed. Both routers use Wi-Fi 6, which means better speeds and efficiency compared to older models. However, the TP-Link Archer AX5400 clearly leads when it comes to maximum throughput.
The Asus RT-AX1800S offers a maximum combined speed of 1,774 Mbps. That’s split between 574 Mbps on the 2.4GHz band and 1,201 Mbps on the 5GHz band. In practical terms, this is enough for typical households with streaming, gaming, and work-from-home needs. Most internet plans under 1Gbps won’t even reach this router’s full speed.
The TP-Link Archer AX5400 is much faster on paper, with a combined speed of up to 5,400 Mbps (574 Mbps on 2.4GHz, 4,804 Mbps on 5GHz). This makes it better for homes with many devices, 4K streaming, or lots of smart gadgets. In real use, you’ll rarely hit the top speed, but the extra headroom helps with congestion and heavy use.
Real-world Usage
In day-to-day use, the difference in speed is noticeable only if you have a very fast internet plan or many devices active at once. For example, families with several 4K TVs, gamers, or those who work from home and transfer large files will benefit more from the Archer AX5400.
If you have a small apartment or just a few devices, the Asus RT-AX1800S is likely enough. For busy homes or small offices, the extra power of the TP-Link model gives you more room to grow.
Wired Vs Wireless
Both routers come with Gigabit Ethernet ports for wired connections. This is great for gaming, streaming boxes, or desktops that need the lowest possible lag. While both have the same number of Ethernet ports, the TP-Link’s stronger processor and RAM help with more simultaneous connections.

Coverage And Range
A router’s range depends on its antennas, power, and how it manages Wi-Fi signals.
- Asus RT-AX1800S: Covers about 2,000–2,200 square feet in open spaces. Four external antennas help spread the signal, but walls and floors can reduce range. It’s ideal for apartments or small homes.
- TP-Link Archer AX5400: Covers up to 2,500–2,700 square feet in open conditions. Its advanced signal processing and high-gain antennas mean stronger Wi-Fi in larger homes or across more floors.
Mesh System Support
Both routers support mesh networking. Asus calls this AiMesh; TP-Link uses OneMesh. Mesh lets you add more routers or range extenders to cover dead zones.
- AiMesh: Works best if you add other Asus routers with AiMesh support.
- OneMesh: Works with TP-Link OneMesh extenders, but not all TP-Link routers.
Mesh is a must-have for large homes or tricky layouts. If you plan to expand, check which mesh systems fit your brand before buying.
Hardware And Design
When you place a router in your home, looks and build matter more than you might think. The Asus RT-AX1800S has a classic, angular design with four sturdy antennas. It’s compact and fits well on a shelf or table. The black finish and green LED indicators give it a modern feel.
The TP-Link Archer AX5400 is larger, with a more aggressive, futuristic look. The four external antennas are bigger and more adjustable. Its size means better cooling, which can help with long-term stability, especially in warm climates or busy homes.
Usb Port And Storage
Both routers offer a USB 3.0 port (the Asus calls it USB 3.2 Gen 1, but speeds are similar). You can plug in a hard drive or USB stick to share files, stream media, or even set up a simple home server.
While both routers perform well with USB drives, the Archer AX5400’s stronger CPU and RAM can handle more users or faster file transfers. If you often move big files across your network, this could matter.
Software, Control, And Security
Modern routers aren’t just hardware—they’re smart devices with apps, cloud access, and security features.
Setup And Apps
- Asus RT-AX1800S: Uses the Asus Router App. Setup is fast, and you can manage your network, set up guest Wi-Fi, or see which devices are connected. The web interface is simple but powerful, great for both beginners and advanced users.
- TP-Link Archer AX5400: Uses the TP-Link Tether App. It’s user-friendly and guides you through setup step by step. The web dashboard is well-designed and makes it easy to adjust advanced settings.
Both apps let you reboot the router, manage parental controls, and update firmware from your phone.
Parental Controls
Both routers offer basic parental controls. You can block websites, set schedules for internet access, and create guest networks. TP-Link’s interface is a bit more modern, but Asus gives you deeper settings if you want to customize.
Security Features
Security is a growing concern. Both models support WPA3 encryption (the latest Wi-Fi security standard). This keeps your network safe from most common attacks.
The Asus router includes AiProtection Classic by Trend Micro (a basic version of their security suite), which blocks malicious sites and scans for infected devices. TP-Link’s HomeShield (basic version) offers similar protections, with options to block threats and see reports.
It’s important to know that advanced features (like better parental controls or network scanning) often require a subscription on both brands. Read the fine print if you need more than basic security.
Advanced Features
Both routers offer extras that can make life easier or boost performance.
Quality Of Service (qos)
- Asus RT-AX1800S: Includes Adaptive QoS. You can prioritize gaming, streaming, or work traffic, but the options are simple.
- TP-Link Archer AX5400: Offers Advanced QoS with more presets and customization. You can prioritize devices or apps with more detail.
If you have gamers or remote workers in the house, strong QoS is useful to avoid lag or buffering.
Vpn Support
Both models support basic VPN setups. Asus is a bit more flexible, letting you run a VPN server directly on the router, so you can access your home network securely when away.
Voice Assistant Compatibility
The Archer AX5400 works with Amazon Alexa for simple voice commands like turning on guest Wi-Fi. Asus routers do not support voice assistants natively.

Price And Value
Price is always a big factor. Here’s a quick look at what you can expect:
| Model | Typical Price (USD) | Best For |
|---|---|---|
| Asus RT-AX1800S | $70–$95 | Budget buyers, small homes |
| TP-Link Archer AX5400 | $135–$180 | Power users, large homes |
The Asus RT-AX1800S is one of the most affordable Wi-Fi 6 routers from a major brand. For the price, you get excellent value, especially if you don’t need high-end speed or advanced features.
The TP-Link Archer AX5400 costs more but justifies it with much higher maximum speeds, more RAM, and stronger hardware. If you want to future-proof your network or have many users, the extra investment makes sense.
