ASUS RT-AX1800S/CA Wi-Fi 6 Router
The ASUS RT-AX1800S/CA is a dual-band Wi-Fi 6 wireless router designed for households upgrading to the 802.11ax standard. It delivers combined wireless speeds up to 1800 Mbps with 574 Mbps on the 2.4 GHz band and 1201 Mbps on the 5 GHz band. Four external antennas support MU-MIMO and OFDMA for simultaneous device communication. AiProtection Classic powered by Trend Micro provides network security for connected devices.
Check Your ISP Modem and Client Devices
Verify that your internet service provider modem or gateway offers a Gigabit Ethernet WAN handoff to use the 10/100/1000M WAN port. Confirm that your laptops, phones or IoT gear support Wi-Fi 6 (802.11ax) to benefit from 1024-QAM and OFDMA efficiency gains. Ensure you have a standard mains outlet for the 12 V 1.5 A power adapter operating on 110 V to 240 V at 50 Hz to 60 Hz. The router includes WPS and reset buttons plus a power switch for basic control.
Wired and Wireless Expansion
Connect up to four wired clients such as PCs, NAS units or smart TVs to the four Gigabit LAN ports for 1000 Mbps links. The dual-band radios free the 2.4 GHz band for legacy devices while moving high-throughput traffic to the 5 GHz band. VPN client support for L2TP, OpenVPN and PPTP plus VPN server options for IPsec, OpenVPN and PPTP allow secure remote access without extra hardware. Status LEDs for power, 2.4G, 5G, LAN and WAN give at-a-glance link health.

Questions sur cet article
What comes in the box with the RT-AX1800S/CA router and do I need to buy any cables separately?
The router ships with four external antennas, a 12 V 1.5 A power adapter and one Gigabit WAN port plus four Gigabit LAN ports for wired connections. Ethernet cables for those ports are not included.
The spec lists 574 Mbps on 2.4 GHz and 1201 Mbps on 5 GHz — which band should I prioritise for my devices?
Use the 5 GHz band for devices that support Wi-Fi 6 and need the 1201 Mbps link rate; keep 2.4 GHz for older clients or longer range where its 574 Mbps maximum is sufficient.
What does the AX1800 1.8 Gbps total mean for actual throughput in my home?
The 1800 Mbps figure combines the 574 Mbps 2.4 GHz and 1201 Mbps 5 GHz PHY rates; real-world throughput will be lower and depends on client capabilities, channel width and interference.
