Technical Specs: Raw Power with OpenWRT

The Flint 3 isn't a typical router. It's built for power users who want full control.

  • WiFi 7 Tri-band: Speeds up to 9300 Mbps with MLO (Multi-Link Operation).
  • 5 x 2.5 GbE ports: All Ethernet ports are high-speed, removing LAN bottlenecks.
  • Powerful hardware: Quad-core processor and a USB 3.0 port for basic NAS functionality.
  • Open software: Based on OpenWRT, allowing almost limitless customization.

Unboxing and Getting Started

The package includes the router, a quality Ethernet cable, and a 12V/4A power adapter. Physically it's a sturdy unit with four high-gain antennas.

Initial Setup, Step by Step

  1. Physical connection: Connect the ISP router's cable to the Flint 3 WAN port.
  2. GL.iNet interface: Access it via the web. The dashboard is very intuitive, ideal for users who don't want to deal with command lines.
  3. Manual configuration: To integrate it into a complex network (as I did in my lab), set the WAN to a static IP and adjust the network mask so it can coexist with the main router without conflicts.

WiFi 7 and MLO: The Wireless Revolution

The standout feature is MLO. Unlike WiFi 6 routers, WiFi 7 allows a device to connect to the 2.4GHz, 5GHz and 6GHz bands at the same time.

  • Benefit: Greater stability and lower latency for your sensors and security cameras.
  • Speed test: In our tests we hit the line's maximum over WiFi, far exceeding the limits of standard routers.

Advanced features for pro users

1. WireGuard and OpenVPN

The Flint 3 can act as a VPN Server and Client. Setting up WireGuard takes seconds. This lets you securely access your home to manage Home Assistant without exposing ports to the internet.

2. Built-in AdGuard Home

Say goodbye to ads across your network. Enabling AdGuard Home on the router blocks ads and trackers on Smart TVs, phones, and tablets without installing anything else.

3. DNS and Security (Tor)

Includes options to configure DNS over TLS (Cloudflare, Google) and the ability to route traffic through the Tor network for maximum privacy.

4. OpenWRT LuCI

For techies, access to the LuCI interface lets you manage packages, advanced firewall rules, and network settings that no consumer router offers.

Performance on 2.5 GbE networks

Thanks to its five 2.5 Gigabit ports, file transfers between a PC and a NAS (like Synology or QNAP) fly. It's the perfect setup for those who edit video or handle heavy backups.

Integration with Home Assistant and smart home systems

The Flint 3 can handle hundreds of IoT devices without breaking a sweat. Additionally, its compatibility with WiFi Mesh systems lets you extend coverage in large homes without losing performance.
