TP-Link Archer AX18 review

The Archer AX18 is a TP-Link Wi-Fi 6 router from 2023. It is a single unit. TP-Link doesn't sell it as a kit, so there are no extra nodes. That makes it a router for one location, not a whole-house mesh.

It is dual-band. The 5 GHz band is rated at 1201 Mbps using 802.11ax, and the 2.4 GHz band at 300 Mbps using 802.11n. It is not tri-band and it is not 6E. It stays backward compatible with older 11a/b/g/n/ac devices, so older kit can still join.

The 2.4 GHz band runs at 802.11n, not 11ax. If you have many older or low-power devices on that band, expect the 300 Mbps rating to be the ceiling. The 5 GHz band carries the Wi-Fi 6 speed.

TP-Link doesn't publish a coverage area or range figure for this model. What it does list is four external antennas and beamforming. That tells you the hardware is built to push signal in a targeted way, but it doesn't tell you how many rooms or square metres it will cover. With one router and no published figure, a large or multi-storey home is a gamble. A small flat or an average house is the more sensible target.

The back has one gigabit WAN port and three gigabit LAN ports. There is no 2.5GbE or 10GbE. For a typical home that is enough for a few wired devices such as a PC, a console and a NAS. With three LAN ports you can fill them quickly, so a homelab with several wired machines would need a switch.

The 5 GHz rating of 1201 Mbps is higher than the 1 Gbps WAN port. Gigabit-only wiring is the limit on the wired side, and there is no faster port to use.

Security support starts with WPA3-Personal, alongside WPA2-PSK and mixed modes. That mix lets newer devices use WPA3 while older ones stay connected on WPA2.

The feature list also includes a guest network, access control with whitelist and blacklist, and parental controls. Auto firmware upgrade is listed too, which suits people who don't want to check for updates by hand.

The firmware record is visible in the download centres. Version 1.1.21 is dated 4 February 2024 and adds CWMP support and improved system safety. Version 1.1.22 is dated 17 June 2024. Version 1.5.0 is dated 9 June 2026 and improves overall security and stability. Version 1.5.1 is dated 4 September 2026. That shows updates continuing into late 2026, three years after the 2023 release.

Two limits matter for technical users. The datasheet lists VPN Support for remote access to a local NAS, and it states plainly that this is not a VPN server. And VLAN support is not published. If you want to split a network into VLANs or run a VPN server on the router, the specifications give you no reason to expect either.

The sources show no feature paywalls. The datasheet lists no subscription features, though it doesn't say outright that there are none.

The price history shows movement. The lowest listed price was in June 2026 and the highest was well above that, so timing affects what you pay. Compare the price you see with that history before buying.

At its usual level, the AX18 offers Wi-Fi 6, WPA3 and a sensible feature set. Its trade-offs are clear from the specifications: dual-band only, gigabit-only wiring, no published coverage figure and no VPN server.

The AX18 is a straightforward choice for a small home that wants Wi-Fi 6 with WPA3, guest access and parental controls. The firmware record gives some confidence in ongoing support. If you need multi-gig ports, VLANs, a VPN server or mesh expansion, the specifications point elsewhere.
