What happened?

I am using Fenvi AX1800(MT7921AU). It seems like its running slow on OpenWRT router, but runs fast on my PC(Ubuntu-24.04).

I tested the USB port if that was the issue, but it's not. Tested with USB3 SSD, got around 103MBps

Edit: Forgot to mention, The router I am using GL.INet MT1300
