The ASUS RT-AX1800S is a dual-band Wi-Fi 6 router with 2.4GHz and 5GHz bands. It features four 1Gbps LAN ports and a 1Gbps WAN port. It's compatible with ASUS' AiMesh, which allows you to use other ASUS routers as additional mesh access points.
The ASUS RT-AX1800S is decent for a single-story home or condo. It delivers good top speeds and is suitable for high-speed downloads and 4k video streaming. Still, it lacks DFS (Dynamic Frequency Selection) support, so its speeds may be slower if you live in a congested wireless environment like an apartment building.
The ASUS AX1800S is adequate if you live in a multi-level house. It delivers good top speeds suitable for downloading large files quickly when you're close to it, but it's a standalone router and slows down when you're far away from it. It supports AiMesh, so you can pair it with compatible ASUS devices to improve its coverage.
This router delivers good speeds suitable for an internet connection of up to ~600Mbps. However, it doesn't support DFS (Dynamic Frequency Selection), so it can't access DFS-only channels, which would help its speeds in congested wireless environments.
This router has an okay range, but it's a standalone unit, so depending on your home's size, layout, and construction, you might experience dropouts. It supports AiMesh, so you can pair it with compatible ASUS devices to improve its coverage.
