The internal Realtek wireless radio drivers are notoriously difficult to port to modern Linux kernels. Wireless may suffer from low throughput, frequent drops, or complete failure to initialize.
You will need to serve the OpenWrt firmware file using a TFTP server on your PC and use the U-Boot command line to download and write the image to flash.
Key components needed for RTL8196E:
However, unlike its Broadcom or Atheros counterparts, the RTL8196E holds a unique and somewhat notorious position in the open-source community. This feature explores the architecture of the RTL8196E, the history of its support in OpenWrt, and why it remains one of the most challenging platforms to adapt for modern networking.

Let us compare a "hacked" RTL8196E (4MB flash, 32MB RAM, Linux 3.10) to a stock OpenWrt router (MT7620, 16MB flash, 128MB RAM).
Frequently restricted to 32MB, leaving very little room for background processes or modern web interfaces like LuCI. The Current State of Support rtl8196e openwrt
While the RTL8196E SoC and OpenWRT are compatible, there are some challenges and limitations to consider:
If you need a reliable, high-performance OpenWrt router, consider upgrading to devices powered by modern architectures with native, flawless upstream support: The internal Realtek wireless radio drivers are notoriously
Because these devices lack a unified bootloader like U-Boot, the installation process is more technical than a typical router flash. Most RTL8196E chips come pre-loaded with a proprietary Realtek bootloader that supports a specific TFTP (Trivial File Transfer Protocol) recovery mode. Based on community guides (primarily from the Luo-Ye repository), the universal steps are as follows:
To understand the OpenWrt situation, one must first understand the hardware. The RTL8196E is part of Realtek’s "Basil" series. It was designed as a cost-effective solution for 802.11n Wi-Fi routers, typically paired with a dedicated Realtek Wi-Fi chip (like the RTL8192CE or RTL8188ER).
