GL.iNet GL-AXT1800 (Slate AX) Review: The Travel Router That Actually Performs

Most people don't need a travel router. The GL.iNet GL-AXT1800, also known as the Slate AX, is for the other people — the ones who bring a VPN client to every hotel room, who want to know exactly what network their devices are connecting to, and who think "OpenWrt pre-installed" sounds like a feature rather than a warning.

Key Features

The Slate AX is a dual-band Wi-Fi 6 router in a package roughly the size of a thick paperback book. It runs a 1.2 GHz dual-core ARM processor with 512MB RAM and 8GB of storage — modest numbers compared to a home router, but entirely adequate for its intended use cases: travel connectivity, VPN routing, and portable network management. Wi-Fi 6 radios cover 2.4 GHz (600 Mbps) and 5 GHz (1,200 Mbps) with OFDMA and MU-MIMO support. The WAN port is Gigabit Ethernet; a USB 3.0 port accepts a USB-to-2.5G Ethernet adapter for faster wired connections.

OpenWrt is the operating system underneath, which means the full repository of OpenWrt packages — thousands of networking tools, firewalls, VPN protocols, traffic analyzers — is available to install. GL.iNet layers a clean web UI on top of OpenWrt that makes the most common configurations accessible without touching the terminal.

Who It's Best For

The Slate AX serves three distinct groups. First: frequent travelers who use a VPN for privacy on hotel and airport Wi-Fi, and who want a single device that handles VPN routing for all their devices rather than installing a VPN app on each. Second: IT professionals and network engineers who want a portable router for testing, site surveys, or field work. Third: home lab enthusiasts who want to explore OpenWrt capabilities on current hardware without repurposing a production router.

If you've ever been frustrated that your hotel TV, work laptop, and phone all need separate VPN configuration, the Slate AX solves the problem at the network level: one device connects to the hotel Wi-Fi, the Slate AX handles the VPN tunnel, and all your devices connect normally through it.

Standout Capabilities

The VPN client implementation is the Slate AX's defining feature. WireGuard and OpenVPN are both built into the GL.iNet interface as first-class configurations — not afterthoughts or manual installations. You paste in your WireGuard config file or OpenVPN credentials, click connect, and the router tunnels all downstream traffic through the VPN. Killswitch mode blocks internet traffic if the VPN drops, protecting against exposure on untrusted networks.

Repeater mode allows the Slate AX to join an existing Wi-Fi network (hotel, Airbnb, café) and rebroadcast it as a private SSID with its own firewall. This means your devices never directly join an untrusted public network — they see the Slate AX's private network and are protected from other guests on the same public hotspot.

The GL.iNet GL-AXT1800 is available on Amazon. For travelers and advanced users who need a portable, VPN-ready router on Wi-Fi 6 hardware, nothing else at this price comes close.
