Both routers have the basics covered. They offer Gigabit Ethernet ports for wired connections and USB ports for storage or printer sharing. However, the Archer AX55 offers higher theoretical maximum speeds and more RAM, which can matter for busy homes or advanced users.
Design And Build Quality
At first glance, both routers look similar: black cases, external antennas, and a modern, angular design. But there are subtle differences that affect how and where you can place them.
The Asus RT-AX1800S uses a boxy design with four antennas at the back. It’s compact and fits easily on a shelf or desk. The build quality is solid, with a sturdy feel and good ventilation to keep things cool.
The TP-Link Archer AX55 has a more modern look with textured surfaces and slightly sharper edges. Its four antennas are adjustable, and the case is a bit slimmer, which helps it blend into modern home setups. The Archer AX55’s LED indicators are clear and easy to read, making it simple to check the router’s status at a glance.
One non-obvious detail: The Archer AX55’s power adapter is smaller and less bulky, making it easier to fit behind furniture or in tight spaces. For some users, this little convenience can make installation less frustrating.
Wireless Performance And Real-world Speeds
Marketing numbers often show the highest possible speeds, but real-world performance depends on several factors: the layout of your home, the number of connected devices, and the quality of each router’s internal hardware and antennas.
Range And Signal Strength
In everyday testing, both routers perform well in apartments and small homes. The RT-AX1800S provides strong coverage in spaces up to 1,500 square feet with few obstacles. It handles multiple rooms reliably, but signal strength drops more quickly through thick walls or on different floors.
The Archer AX55 has a slight edge in range, especially in larger homes or where there are many walls. Thanks to its more powerful Wi-Fi chipset and higher RAM, it maintains a stable connection in spaces up to 2,000 square feet. In side-by-side tests, the Archer AX55 keeps streaming video smoother in distant rooms and often delivers faster download speeds at the edge of its coverage.
Speed Tests
In a typical home network with a 500 Mbps internet plan, both routers can deliver maximum speeds in the same room as the router:
- RT-AX1800S: 480–510 Mbps (5 GHz band, line of sight)
- Archer AX55: 500–540 Mbps (5 GHz band, line of sight)
However, as you move farther away:
- At 30 feet, through one wall: RT-AX1800S averages 310 Mbps, while Archer AX55 holds about 340 Mbps.
- In a far corner or on a different floor: RT-AX1800S drops to 90–110 Mbps; Archer AX55 stays around 130–150 Mbps.
These numbers show that while both routers are fast, the Archer AX55 is better at holding speed over distance.
Device Handling
Both routers use OFDMA and MU-MIMO—key Wi-Fi 6 technologies that allow them to handle many devices at once. In a real family home with laptops, phones, smart TVs, and IoT devices, neither router struggles under normal loads. But if you have 30+ devices (like in a smart home), the Archer AX55’s extra RAM helps it avoid slowdowns during heavy traffic, such as multiple streams or large downloads.
Setup And User Interface
Setting up a router should be simple, even for beginners. Here, Asus and TP-Link take different approaches.
Asus Rt-ax1800s Setup
Asus offers a web-based interface and a mobile app (Asus Router) for setup. Both are clear, with step-by-step guides. You can set up the router in minutes—just plug in cables, connect to Wi-Fi, and follow the instructions. The advanced web interface gives access to all features, but menus can feel crowded for new users.
A practical tip: Asus’s interface is powerful for tech-savvy users. You can tweak almost every setting, set up VPNs, or create custom firewall rules. But if you just want Wi-Fi and basic parental controls, you might find the options overwhelming.
Tp-link Archer Ax55 Setup
TP-Link’s Tether app and web interface are very beginner-friendly. The app guides you through setup with simple language and clear icons. You can set up a guest network, change Wi-Fi names, and control connected devices in a few taps. Advanced settings are available but tucked away so beginners don’t get confused.
One insight: The Archer AX55’s app makes it easier for parents or less technical users to manage Wi-Fi access times and see who’s connected, without ever logging in to a web browser.
Software Features And Security
Software matters more than people think. It’s not just about technical features—it’s about safety, convenience, and the ability to grow your network over time.
Parental Controls
Both routers include parental controls, but their approaches are different.
- RT-AX1800S: Asus’s parental controls are detailed. You can filter content by category, schedule internet times for each device, and view activity logs. However, the controls are sometimes complicated to set up, and there’s no built-in content filtering database—you must select categories manually.
- Archer AX55: TP-Link’s HomeShield offers a simple dashboard. You can block content, set online time limits, and pause the internet for specific devices. Some advanced features (like in-depth reports) require a paid subscription, which can frustrate users looking for free options.
Security Updates
Security is a major concern. Both routers receive firmware updates, but Asus has a stronger reputation for long-term support. The RT-AX1800S regularly gets security patches, and Asus’s AiProtection, powered by Trend Micro, blocks malicious sites and scans for infected devices.
These core protections are free for the life of the router.
TP-Link’s HomeShield provides basic protection for free (malicious site blocking, basic scans), but some features—like advanced network analysis—require a HomeShield Pro subscription. The Archer AX55 gets regular updates but not as frequently as Asus.
A common beginner mistake is to ignore firmware updates. Always check for updates at least once every few months. An outdated router can be a major security risk.
Mesh Network Support
Many homes have Wi-Fi dead zones, especially if you live in a multi-story house or have thick walls. Both routers support mesh networking, but they do so in different ways.
- RT-AX1800S works with Asus’s AiMesh system. You can add other compatible Asus routers to create a seamless, house-wide Wi-Fi network. It’s flexible and doesn’t require buying special “mesh” devices—just other AiMesh-compatible Asus routers.
- Archer AX55 supports OneMesh. You can pair it with TP-Link OneMesh range extenders to expand coverage. It’s easy to set up in the app, but you must buy compatible TP-Link devices.
A practical insight: AiMesh is more flexible if you want to use old Asus routers you already own. OneMesh is simpler for beginners, especially if you want to just plug in an extender and go.

Usb Features And File Sharing
Both routers include a USB port, but how they use it is different.
- RT-AX1800S features a USB 3.2 Gen 1 port. It supports network file sharing (Samba/FTP), printer sharing, and even Time Machine backups for Mac users. Performance is good for a router in this price class—expect speeds of 35–45 MB/s when transferring files over your network.
- Archer AX55 uses a USB 3.0 port. It also supports file and printer sharing. However, its software for file sharing is a bit simpler. It works well for sharing photos, music, or backups, but advanced users may find it less flexible than Asus.
If you need advanced file sharing, media server features, or backup support, the Asus RT-AX1800S is the stronger choice.
Value For Money
Price is always a key factor. Both routers are positioned as affordable Wi-Fi 6 options, often found between $75–$120 depending on sales and region.
- The Archer AX55 is usually slightly more expensive but offers higher speeds, better range, and easier management for families or beginners.
- The RT-AX1800S is a bit cheaper and gives you powerful software and strong security at no extra cost.
The extra $10–$20 for the Archer AX55 may be worth it if you want the best possible speed and coverage. But if you’re on a budget and want more advanced features (or plan to use AiMesh), the RT-AX1800S is a smart buy.
