The ASUS RT-AX55, sometimes called the ASUS AX1800, is a dual-band Wi-Fi 6 router with 2.4GHz and 5GHz bands. It features four LAN ports and a WAN port rated at 1Gbps speeds. It's compatible with ASUS' AiMesh, which allows you to use other ASUS routers as additional mesh access points.
The ASUS RT-AX55 is a decent router if you live in an apartment, condo, or single-story home. It delivers speeds suitable for 4k video streaming across a single floor, whether you're right next to it or in a different room. It also has adequate wired connectivity with four 1 Gbps LAN ports. The antennas are rather tall, but the router is of a reasonable size and will fit into most living spaces. It also has screw head slots on the bottom, so you have the option to mount it on the wall or ceiling.
The ASUS AX1800 is a decent router if you live in a multi-level house with a backyard. It provides sufficient speeds for high-bandwidth activities like 4k video streaming, whether you're on the same floor or two stories above. Its speeds are also good enough for high-bandwidth use if you're on your deck or in your backyard, but you'll likely experience dropouts if you're very far away from your house.
This router delivers good speeds suitable for an internet connection of up to ~700Mbps. 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 decent 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.
