I flashed OpenWrt on my GL.iNet Flint 2

For quite some time I have been looking into changing my ISP router with another one, as I have been looking for one with way more options to choose towards networking and, that way, I would have a backup in case the one I’m using randomly fails. Finally, I took the plunge and bought the GL.iNet Flint 2 and I installed OpenWrt on it. If you’ve ever felt limited by your router’s built-in settings, or you just like tinkering with your network, OpenWrt is a total game-changer.

Wait, what’s OpenWrt?

For those who don’t know, OpenWrt is a custom, open-source Linux-based firmware for routers. It basically replaces the stock firmware your router comes with, unlocking a ton of advanced features and customization options that most default interfaces don’t even come close to offering.

We’re talking:

  • Advanced firewall and traffic control
  • Built-in VPN support
  • Network monitoring tools
  • Scheduled tasks, ad blockers, and more
  • A full package manager (yeah, like on a real OS!)

Why I did it on the Flint 2

I chose the GL.iNet Flint 2 because it’s already a pretty powerful Wi-Fi 6 router out of the box. It even comes with its own fork of OpenWrt, which is cool — but I wanted vanilla OpenWrt so I could really get into the weeds with custom packages, full control, and a cleaner experience.

And the Flint 2 makes flashing super easy. It has a built-in recovery mode, so even if you mess something up, you can just reflash the firmware through a web interface. No bricking anxiety.

The installation process

Pretty straightforward to be honest:

  1. I checked the OpenWrt Table of Hardware to make sure the Flint 2 was supported (it is!).
  2. Downloaded the correct OpenWrt firmware build from their site.
  3. Uploaded that build image through the router’s internal updater page.
  4. Boom. New life breathed into my router.

Now I’ve got full access to LuCI (the web UI), plus SSH for deeper customization. One thing I wanted to do is have split WiFi networks for myself and guests that visit me, and that is something that OpenWrt allowed me to do, alongside lots more of things I have planned.

Is it for everyone?

If you’re the type who likes to tweak things, optimize performance, or secure your home network beyond just a password, then absolutely. OpenWrt is nerdy in the best way. But even if you’re not super technical, there’s a solid community and tons of guides to walk you through the basics.

If you’re happy with your default router experience? No pressure. But once you try OpenWrt, it’s hard to go back.

Final thoughts

Installing OpenWrt on the Flint 2 took less than 30 minutes and gave me way more control than I thought was possible. If you’re into DIY networking or just want a smarter home setup, give it a try — especially with a router as friendly as the Flint 2.
