OpenWRT is an open-source firmware project aimed at replacing the original firmware on embedded devices, such as routers. It provides a customizable and extensible platform for developers and enthusiasts to modify and enhance their devices. OpenWRT offers a wide range of features, including:

The combination is a stellar example of how older or entry-level networking hardware can be repurposed. While it requires a bit of technical effort to install, the resulting functionality far exceeds what the manufacturer provided out of the box, making it a rewarding project for networking enthusiasts and those looking to secure their home network. rtl8196e openwrt

Best practice:

The hardware specifications fall far below modern OpenWrt system requirements. As of OpenWrt 21.02 and newer, the project enforces a strict minimum resource baseline: Absolute Minimum: 8 MB Flash and 64 MB RAM. Recommended: 16 MB Flash and 128 MB RAM. While it requires a bit of technical effort

Some RTL8196E chips can run at 450MHz. In U-Boot, you can change the PLL register:

Option B — Build a custom image:

The primary obstacle to a smooth, modern OpenWrt experience is that the RTL8196E and the related RTL8196C, D, and 8 families are Lexra cores, which are modified MIPS CPUs that lack some standard instructions. This non-standard architecture requires a custom toolchain and kernel patches, making integration with mainline OpenWrt difficult.

: Light distributions like WavOS or modified vendor firmwares from similar RTL8196E devices are sometimes cross-flashed via TFTP recovery to add minor features like WDS bridging or localized languages. Verdict: Is It Worth It? Recommended: 16 MB Flash and 128 MB RAM
