Attenuation. The reason why x86 virtual openwrt can't run at Gigabit is attenuation, which needs to be tested step by step. If you can't read or say you don't know how to test, please find a professional network engineer to test, not a telecom worker. Those can only be considered weak current engineers. OpenWrt can be described as an embedded Linux distribution rather than trying to build a single static system. OpenWrt's package management provides a completely writable file system with choices and configurations from application vendors, and allows you to customize devices to suit any application.
