The GL.iNet Flint 3 BE9300 is a powerful WiFi 7 router with OpenWRT roots and many features. A few months ago, we looked at the GL.iNet Flint 2, so now, it is time to review the updated Flint 3 model that adds WiFi 7 and more to the package. These usually sell in the $199-219 range at the time of this writing, making them a notable ($50-60) price upgrade over the Flint 2 as well. We thought we would run this one through our tests to see how it performs.

GL.iNet Flint 3 BE9300 Hardware Overview

Like many integrated WiFi gateways, the Flint 3 has an antenna array and a chassis that looks like something out of a SciFi novel landed in 2026.

One fun feature is that there is a status LED at the front of the unit.

The four antenna masts fold down to make it more compact if you need to move it around.

On the sides, there are vents.

On one side, there is a USB 3 Type-A port.

As the name suggests, this is a WiFi 7 device. That “BE9300” tells us this offers in the 9.2–9.3Gbps of aggregate tri-band speeds. It also features Multi-Link Operation (MLO), 320 MHz channels, and 4K-QAM for enhanced, low-latency performance. Of course, performance varies on the application, but the idea is that this is a higher-end device.

On the back, we get the wired networking ports.

On the left rear, we get a DC 12V input, then a 2.5GbE WAN port.

There are then four 2.5GbE LAN ports and a reset button.

On the bottom, we get a lot of vents, mounting holes, and big rubber feet.

Taking the bottom cover off, we were a bit worried about breaking this unit.

Still, with so many vents, we wanted to know if there was a fan inside. As we pulled the PCB out, we saw the fan inside. This would be a bit of a pain to service.

Next, before we get to the management, we wanted to discuss LuCI.

If you go to the advanced settings in the management interface, you will see the option to install LuCI.

For folks who are accustomed to OpenWRT, this is the web interface you have probably seen many times. The reason for this is that GL.iNet is using OpenWRT under the hood. Since it is a Qualcomm IPQ5332 device, this is unlikely to be a device you can just install OpenWRT on. Instead, it is more of a fork from GL.iNet, which is a bit of a bummer.

Still, with LuCI you can do many things, like setup firewall rules.

Here is the Firewall Status of the default installation, which does not have too much going on.

Perhaps the biggest point here is that, at some level, it is actually based on OpenWRT.
