Configure your Internet connection (PPPoE, DHCP).
The primary obstacle to official rtl8196e openwrt support has always been, paradoxically, Realtek themselves. To get their hardware functional, Realtek took a very old (circa 2013) version of the Linux kernel, heavily modified it to support the RTL819x series, and then never contributed these changes back to the mainline Linux kernel.
For a better experience, prioritize devices that already have Flash, or use a "squashfs" image for better stability.
Use an and kernel patches. Example build environment: rtl8196e openwrt
Integrated 5-port Fast Ethernet switch (10/100 Mbps) and 2x2 2.4GHz b/g/n WLAN. The Lexra Architecture Problem
Developers have successfully backported older, highly optimized versions of OpenWrt (such as Barrier Breaker 14.07 or Chaos Calmer 15.05) using modified toolchains. These custom builds rely on the Realtek Linux 2.6.x or 3.10.x kernel SDKs, which include proprietary patches for the Lexra CPU instruction set and the integrated Realtek Wi-Fi driver. How Developers Build OpenWrt for RTL8196E
: While the ethernet switch ports require vendor-specific kernel adjustments, the onboard 2.4GHz Wi-Fi radio can sometimes interface using the open-source rtl8192ee driver within mac80211 stack wrappers [1.3.1]. Configure your Internet connection (PPPoE, DHCP)
Some community forks exist:

Most consumer devices utilizing the RTL8196E were engineered to be as cheap as possible. They frequently shipped with: 16 MB or 32 MB of RAM Working Realtek SoC RTL8196E 97D 97F in last master For a better experience, prioritize devices that already
After flashing and rebooting, the router will usually default to IP 192.168.1.1 . Connect via Ethernet.
Realtek based its initial modifications for this SoC on an ancient version of the Linux kernel. Crucially, these changes were never contributed back to the mainline Linux kernel. This has left the OpenWrt project, which strives to stay close to the mainline kernel, in a difficult position. Any volunteer looking to add official support for the RTL8196E would face a monumental task of re-integrating code that has been out in the cold for many years, effectively reverse-engineering the hardware.
: It lacks unaligned load/store instructions ( lwl , lwr , etc.).
Once done, your compiled factory and sysupgrade .bin images will be located in the bin/rtl819xd/ directory. Methods for Flashing the Firmware
