GL-MT300N-V2 Mango mixed speed results on GL.iNet firmware

[Tudor]

Hi guys, I've been playing with my Mango router for a bit to test its maximum limits, comparing three different firmware versions. All setups were tested in access point mode with the best quality signal I could achieve (50cm away from AP), so that firewall/other processes wouldn't clog up the CPU/RAM.

With openWRT 23.05.5 pulled from their website ([OpenWrt Wiki] GL.iNet GL-MT300N V2) and with openWRT wiki to create an AP only setup, I managed 79mbps down and 80mbps up:

The second test was done using GL.iNet firmware 3.216, managed 54 down 61 up:

And lastly, using GL.iNet firmware 4.3.18, I managed 79 down 56 up at best:

Even going into LuCI and disabling + stopping unnecessary services in acces point mode (firewall, dnsmasq, odhcpd for example), I did not manage to improve speeds up to the clean openWRT firmware standards. My question is, is this firmware still being improved? it feels like it's still got hidden potential. I see a clear improvement from v3 to v4 firmware.

Are you running the speed tests from the shell of the router?

Feature Request Speed Test

You can try this: wget https://install.speedtest.net/app/cli/ookla-speedtest-1.2.0-linux-aarch64.tgz && tar xzf ookla-speedtest-1.2.0-linux-aarch64.tgz && ./speedtest

How would running speedtests from the router shell prove wifi performance?

My ISP speed is 150mbps symmetrical so I'm maxing out the 100mbps LAN in any case.

iPerf3 for beginners

Hey the use of iperf3 is very simple and does not require much study I will now go into the use via SSH - presumably the plug-in only takes care of the installation. On the router connect to your router via SSH (e.g. ssh root@192.168.177.1) update the software database: opkg update install iperf3: opkg install iperf3 start iperf3 in server mode: iperf3 -s On any client, e.g. Windows: Download iperf3: iPerf - Download iPerf3 and original iPerf pre-compiled binaries Connec…

run iperf3 on the Mango, then you are testing throughput simply between the Mango and the wireless client running iperf3 to test throughput of the WiFi.

iperf3 LAN results are worse than speedtest.net but the trend follows my initial statement. All tests performed in best quality wifi, around -30dBm.

Try adding -w 4M to the iperf command. I've found that in certain circumstances I get much better results.
