Configure the internal switch ports into distinct Virtual LANs (VLANs) to isolate smart home IoT traffic.

The RTL8196E chip, when paired with OpenWRT firmware, offers a powerful combination for customizing and enhancing your router's capabilities. With its robust architecture, customizable features, and community-driven support, this pairing is ideal for developers, enthusiasts, and organizations looking to create tailored networking solutions. By exploring the possibilities of RTL8196E with OpenWRT, you can unlock new features, improve performance, and take your networking experience to the next level.

The RTL8196E SoC is supported by OpenWRT, which provides a stable and feature-rich operating system for devices based on this SoC. OpenWRT for RTL8196E offers: Set one immediately

Because standard Linux tools and compilers assume a full MIPS ISA, executing stock MIPS binaries on an results in an immediate crash or kernel panic.

: Turn an old router into a highly configurable 4-port smart switch with VLAN tagging support.

RTL8196E is not supported by mainstream OpenWrt stable releases. You must use snapshot builds or community forks like LEDE (historic) or OpenWrt-rtl .
