GL.iNet Flint 3 vs Archer BE550: OpenWrt flexibility or TP-Link simplicity?
The GL.iNet Flint 3 (GL-BE9300) is the better pick if you need built-in VPN routing, ad blocking, or OpenWrt-level control. The Archer BE550 is easier to set up and has a more polished app experience with TP-Link's Tether and HomeShield. Both are tri-band BE9300 class Wi-Fi 7 routers with five 2.5G Ethernet ports.
On paper, the specs are nearly identical. Both run tri-band Wi-Fi 7, both have 2x2 radios on each band, and both top out around 9,200 Mbps of combined theoretical bandwidth. The Flint 3 uses a Qualcomm IPQ5332 SoC clocked at 1.5 GHz with 1 GB RAM and 8 GB eMMC, while the BE550 V1 runs Qualcomm's Network Pro 620 at 2.2 GHz with 1 GB RAM. The BE550 V1 has the faster CPU on paper, though both handle typical home networking loads without issues.
The real split is software. The Flint 3 runs OpenWrt under GL.iNet's admin panel. That means you get WireGuard VPN at up to 680 Mbps (per GL.iNet's spec), OpenVPN, AdGuard Home, failover, tethering support, and LuCI access for granular firewall and routing rules. The BE550 runs TP-Link's proprietary firmware with a web UI and the Tether app. It offers VPN client/server support and EasyMesh for mesh expansion, but no ad blocking and no SSH or command-line access.
Where the GL.iNet Flint 3 and Archer BE550 are evenly matched
Both use tri-band Wi-Fi 7, both have 2x2 radios across the three bands, and both support 320MHz channels, 4K-QAM and Multi-Link Operation (MLO). Their theoretical combined wireless speeds are in the same BE9300 class. The Flint 3 uses a Qualcomm IPQ5332 quad-core processor running at 1.5GHz, with 1GB RAM and 8GB eMMC storage. The Archer BE550 V1 uses Qualcomm's Network Pro 620 platform with 1GB RAM. The BE550 has a faster processor on paper, but that does not translate into a real-world speed advantage right away for home networking.
Flint 3 and Archer BE550 both have five 2.5Gbps Ethernet ports, which is useful if you have a multi-gigabit internet connection or several devices such as a NAS, desktop PC or network switch that can actually use more than 1Gbps.
The layouts are slightly different. The Flint 3 has one dedicated 2.5G WAN port, one 2.5G port that can switch between WAN and LAN, and three 2.5G LAN ports. That switchable port is useful if you want to build a dual-WAN setup. The BE550 has one 2.5G WAN port and four dedicated 2.5G LAN ports. For a conventional home network, that arrangement is arguably easier to understand - one port for the internet and four for wired devices. Both routers also have a USB 3.0 port.
The performance difference that comes with the software
Flint 3 gives more control over the network
The Flint 3 runs GL.iNet's OpenWrt-based firmware, with GL.iNet's own admin interface on top. That gives you features that are unusual on mainstream consumer Wi-Fi routers.
WireGuard and OpenVPN are built in, with GL.iNet quoting VPN speeds of up to 680 Mbps. You also get AdGuard Home for network-wide ad and tracker blocking, policy-based routing, multi-WAN, failover, Tailscale, ZeroTier and other networking tools.
That makes the Flint 3 useful when the router itself needs to do more than simply provide Wi-Fi. For example, you can route selected devices through a VPN while leaving others on the normal connection. You can use AdGuard Home for devices that cannot run their own ad blocker. You can also use the additional WAN/LAN flexibility for a dual-WAN setup.
There is an important distinction here if you’re considering the Flint 3 specifically for OpenWrt. The router's firmware is built around OpenWrt, but vanilla OpenWrt support for the GL-BE9300 is still a work in progress and currently lives outside the main OpenWrt tree. So Flint 3 gives you a lot of OpenWrt-style flexibility out of the box, but it can’t be described as an officially supported vanilla OpenWrt device yet.
Archer BE550 keeps network management simple
The Archer BE550 takes a more conventional approach. You get TP-Link's web interface and Tether app, along with HomeShield security and parental controls. EasyMesh support also lets you expand the network using compatible TP-Link routers and range extenders.
BE550 is more about putting common networking tasks into a controlled interface. TP-Link's firmware updates have also added features and addressed issues with MLO, VPN, PPPoE, IPv6 and Tether. Recent firmware also added VPN Kill Switch support, while earlier updates introduced DoH/DoT and EasyMesh functionality in AP mode.
So the BE550 is better described as a controlled consumer router with a growing feature set, rather than a router with very few advanced options.
The wifi coverage from Flint 3 and BE550
The Flint 3 has four fold-down external antennas, while the BE550 uses six internal antennas with beamforming. There isn't a simple “more antennas means more range” answer to share with you. Antenna design, placement, transmit power, walls and interference all affect actual coverage.
The physical designs are quite different, though. Flint 3 is a larger desktop router with visible antennas that can be folded down. The BE550 keeps its antennas inside the body, giving it a cleaner appearance.
For an Indian living room, that difference can matter if the router is going to sit in an open area rather than inside a cabinet. The BE550 is easier to blend into the room, while the Flint 3's antennas give you more freedom over the router's physical orientation.
Best for:
The Flint 3 suits tinkerers, VPN-heavy users, and small office setups where OpenWrt flexibility, ad blocking, and dual-WAN failover matter more than out-of-the-box simplicity.
Buy the Archer BE550 if you want app-managed setup, EasyMesh expansion, and TP-Link's broader ecosystem of HomeShield-compatible devices.
Not for:
Skip the Flint 3 if you want a plug-and-play experience with zero learning curve, or if you need a USB-free, wall-mount-friendly design.
Skip the BE550 if you need router-level ad blocking, SSH access, WireGuard throughput above 500 Mbps, or a USB port for tethering and storage.
