The ASUS ZenWiFi ET9 is a tri-band Wi-Fi 6E router that's part of ASUS's ZenWiFi lineup of mesh systems. It's available in a one, two, or three-pack. Like the other models in the lineup, it uses ASUS's AiMesh technology, so it's compatible with any other AiMesh-enabled ASUS access point. We bought a two-pack and tested it in dual-mesh mode.
Note: We've removed the Wi-Fi coverage tests, as we're exploring better ways to convey the results that'll be more helpful to users.

Popular Router Comparisons
The ASUS ET9 is a tri-band Wi-Fi 6E mesh router that's part of ASUS's ZenWiFi lineup. It's similar to the ASUS ZenWiFi XT9 but has a 6GHz band instead of a second 5GHz band. Its main competitors include the TP-Link Deco XE5300 and the eero Pro 6E. It delivers very similar performance to both systems but has better connectivity with more LAN ports and a USB port, which the others lack. Lower mid-range Wi-Fi 7 mesh systems, like the TP-Link Deco BE63, are entering the market and offering significantly faster 6GHz speeds for a similar price.

The ASUS ZenWiFi XT9 and the ASUS ZenWiFi ET9 are mesh routers from the same lineup. The ET9 is Wi-Fi 6E while the XT9 is Wi-Fi 6. They deliver similar speeds and range, but the ET9's 6GHz band should perform better in noisy wireless environments.
The ASUS ZenWiFi ET9 and the TP-Link Deco XE5300 are Wi-Fi 6E mesh routers. They deliver similar performance, but the ASUS has better connectivity with more LAN ports, a USB port, and a faster WAN port that's capable of 2.5Gbps.
The ASUS ZenWiFi BT10 and the ASUS ZenWiFi ET9 are tri-band mesh routers that are part of the same lineup. The former is Wi-Fi 7 and the latter is Wi-Fi 6E. The BT10 delivers significantly faster top speeds, while both routers have similarly great range. The BT10 has faster wired networking ports with two 10Gbps Ethernet ports and one 1Gbps port, while the ET9 has three 1Gbps ports and one 2.5Gbps port.
The eero Pro 6E and the ASUS ZenWiFi ET9 are Wi-Fi 6E mesh routers. They have comparable performance, but the eero is slightly faster overall. The ASUS, on the other hand, has better connectivity with more LAN ports and a USB port.
The ASUS ZenWiFi ET9 performs better than the ASUS ROG Rapture GT6. It's faster when you're up close and has better range.
