The GL.iNet Flint 3 is a tri band WiFi 7 router aimed at people who want more control than a typical consumer router allows. It runs firmware based on OpenWrt, ships with five 2.5 gigabit Ethernet ports and has fast built in VPN support, all at a price closer to midrange than flagship. This overview covers the official specs, the current US price, who it suits and the alternatives worth comparing.
GL.iNet Flint 3 specs at a glance
| Spec | GL.iNet Flint 3 |
|---|---|
| WiFi | WiFi 7 (802.11be), tri band: 688 Mbps on 2.4GHz, 2882 Mbps on 5GHz, 5765 Mbps on 6GHz |
| Processor and memory | Qualcomm quad core at 1.5GHz, 1GB DDR4 RAM, 8GB eMMC storage |
| Ethernet | Five 2.5G ports: one WAN, one switchable WAN or LAN, three LAN |
| Other ports | One USB 3.0, reset button |
| VPN | WireGuard and OpenVPN (with DCO), each rated up to 680 Mbps; client and server modes |
| Antennas | Four foldable external antennas |
| Power | 12V 4A adapter, rated under 25W without a USB load |
| Size and weight | 240 x 157 x 74 mm, 848 g |
The speeds above are theoretical link rates per band. Real throughput depends on your devices, distance and walls, and you need WiFi 7 clients to use the 6GHz WiFi 7 features. Older WiFi 6 and WiFi 6E devices still connect, just at their own limits.
Key features that set it apart
A friendly web interface on top, with access to the deeper OpenWrt settings and package system underneath.
Run WireGuard or OpenVPN as a client for your whole network, or as a server to reach home remotely. GL.iNet supports more than 30 VPN providers.
Failover and load balancing across two Ethernet connections, a USB tethered phone, a cellular modem or a WiFi repeater link.
AdGuard Home comes preinstalled for network wide ad blocking, and parental controls are powered by Bark.
Mesh support arrived with firmware 4.10, and GL.iNet lists the Flint 3 among the models that can act as a mesh node, alongside its Slate 7 travel router. That makes it possible to extend coverage with a second unit, though setup is more hands on than with mainstream mesh kits. GL.iNet rates a single unit for up to about 2,000 square feet and more than 120 connected devices.
Price and where to buy
As of October 2026, GL.iNet’s US store lists the Flint 3 at $199.99, down from a $209.90 regular price. It is also sold through major online retailers, where prices move with promotions, so compare before you buy. The router carries no subscription fees for its core features, including VPN and ad blocking.
Who should buy the GL.iNet Flint 3
- Multi gig internet users. A 2.5G WAN port and four more 2.5G ports let a fast fiber line reach your PC or NAS without a gigabit bottleneck.
- VPN users. Router level WireGuard at up to 680 Mbps covers every device at once, including smart TVs and consoles that cannot run VPN apps.
- Home office and small business setups. A second WAN for failover keeps you online when the main connection drops.
- Tinkerers. OpenWrt access means you can add packages and customize far beyond what typical consumer firmware allows.
It is a weaker fit for large multistory homes that need wide coverage out of the box, and for people who prefer polished app driven mesh systems.
Alternatives worth comparing
- GL.iNet Flint 3e ($169.90 at GL.iNet’s US store): dual band WiFi 7 without the 6GHz radio, but the same five 2.5G ports and 680 Mbps VPN ratings. A good saving if your devices do not use 6GHz.
- GL.iNet Flint 2 ($159.99 at the same store): the WiFi 6 predecessor with a similar OpenWrt feature set, fine if you have no WiFi 7 devices yet.
- TP Link Archer BE550: another BE9300 class tri band WiFi 7 router with five 2.5G ports, USB 3.0 and EasyMesh. It suits buyers who prefer TP Link’s app and mesh ecosystem over OpenWrt flexibility.
FAQ
Does the GL.iNet Flint 3 support mesh?
Yes. Mesh arrived with GL.iNet firmware 4.10, and the Flint 3 is on GL.iNet’s list of supported models.
Can the Flint 3 use two internet connections?
Yes. One LAN port can be switched to a second WAN, and the router also supports USB tethering and cellular backup for failover or load balancing.
Is the VPN speed fast enough for gigabit internet?
GL.iNet rates WireGuard and OpenVPN at up to 680 Mbps, so a VPN connection will not use the full speed of a gigabit plan. Traffic outside the VPN is not limited by that figure.
Does it need a subscription?
No. VPN, AdGuard Home and multi WAN work without a paid plan. Optional cloud management tools such as GoodCloud are available but not required.
The verdict
The GL.iNet Flint 3 packs WiFi 7, five 2.5G ports, fast router level VPN and real OpenWrt flexibility into a router that costs about $200. That combination is rare at the price. If you value control, privacy features and multi gig wiring, it belongs on your shortlist. If you want the simplest possible setup, a mainstream mesh system will suit you better.
