Awesome prices on these two previously popular GL.iNet WiFi 6 routers thanks to the 10% off codes redeemable on the listing and the extra 5% off with PayTo code.
The GL-MT6000 Flint 2 is the more high end home router offering with AX6000 WiFi 6 4x4 (2.4GHz: 1148Mbps, 5GHz: 4804Mbps), two 2.5GbE network ports with both being able to be used as WAN ports for a secondary connection, failover etc, four 1GbE LAN ports, USB 3.0 port, 4 antennas and a multi plug charger.
While the GL.iNet GL-MT3000 (Beryl AX) is the more travel friendly option with AX3000 WiFi 6 (2.4GHz: 574Mbps, 5GHz: 2402Mbps), 2.5G WAN port, 1GbE LAN port, USB 3.0 and powered via USB-C.
These are particularly good due to OpenWrt compatibility, VPN support, Wireguard support, VLAN support and more. Possible use cases include AdGuard for network level adblocking, protecting yourself against unsafe networks such as hotel WiFi networks, or as dangerdanger describes a second WiFi network for the kids with Open DNS to filter out 'bad' content. I'm sure others can provide other suggestions in the comments.
That second wifi network is a good shout, thanks!
