Features
Is it for you?
An AX1800 Wi-Fi 6 plug-in range extender from TP-Link with one Gigabit Ethernet port, two external antennas, OneMesh smart roaming and a built-in access point mode for extending any Wi-Fi router.
Choose it if these matter
- OneMesh smart roaming with a compatible TP-Link router gives seamless whole-home coverage under one Wi-Fi name
- One-touch WPS pairing and setup through the TP-Link Tether app (Android/iOS)
Skip it if these rule it out
- Single Gigabit Ethernet port; wired backhaul to a router tops out below the AX1800 wireless rate
- Smart Roaming (802.11k/v) requires client devices that support the 802.11k/v standard
- No USB port and no media-sharing features; it is a pure range extender
