GL.iNet Flint (GL-AX1800) Wi-Fi 6 Secure Home Router

The Flint (GL-AX1800) is the router for households and offices that take security as seriously as speed. Dual-band Wi-Fi 6 delivers up to 600 Mbps (2.4 GHz) + 1,200 Mbps (5 GHz), and a dedicated NPU lets it run VPN encryption at speeds most home routers cannot touch — up to 500 Mbps on both WireGuard and OpenVPN (with DCO).

It is built for busy networks: MU-MIMO and OFDMA support up to 120 connected devices, keeping video meetings smooth and gaming latency low, while five gigabit Ethernet ports handle 4K streaming and heavy-duty wired transfers. WPA3 and IPv6 keep sensitive data encrypted in transit.

Out of the box it blocks the junk too: pre-installed AdGuard Home strips ads and trackers for every device on the network, and Cloudflare DNS over TLS prevents DNS eavesdropping. Underneath sits OpenWrt with root access granted, so you can customise your router fully and install applications on its extra storage.

Frequently asked questions

How fast is the VPN on the Flint?

Up to 500 Mbps over WireGuard and 500 Mbps over OpenVPN (with DCO support) in client mode, tested on a local network — fast enough that the VPN stops being the bottleneck for most broadband connections.

Can it host a VPN server so I can reach home remotely?

Yes. With Web UI 3.0 you can set up a VPN server easily and access your files securely from a remote site as if you were at home; enabling VPN encrypts all traffic within the network automatically.

Is it good for gaming?

Yes — OFDMA data transmission significantly reduces latency by increasing bandwidth and network efficiency, providing ultra-low-latency gaming enhancements alongside the five gigabit wired ports.

How many devices can it handle?

Up to 120 wireless devices simultaneously thanks to Multi-User MIMO — suitable for multi-office collaboration as well as device-heavy smart homes.

Can I customise the firmware?

The Flint ships with OpenWrt and grants root access, so you can fully customise and optimise the device and install applications on its extra storage.
