WiFi on Chinese SBCs: two years of waiting for the basics

Published on June 10, 2026 | Translated from Spanish

The BeagleV Ahead and Lichee Pi 4a boards, low-cost RISC-V based computers, will finally have functional WiFi with the upcoming Linux kernel 7.2 update. A technical change activates the wireless network modules that have been dormant since their launch. The news is sold as an advancement, although it hides a common practice in open-source hardware: selling incomplete products. 📡

Missing drivers: the kernel patches the manufacturer's holes 🛠️

WiFi support arrives through patches that integrate drivers for the Realtek RTL8821CU and RTL8821CE chips, present on these boards since 2022. Until now, the module was useless due to a lack of functional drivers in the main kernel. Manufacturers like SiFive and Alibaba left the work to volunteer Linux developers, who have solved for free a problem that should have been fixed before putting the product on the market. It is not the kernel's merit, but corporate pressure for others to do their job.

The old switcheroo: buy WiFi and wait for a miracle 🎭

So if you bought a BeagleV Ahead to set up a media server or a home NAS, you waited two years using an Ethernet cable while the WiFi slept the sleep of the just. But don't worry, the industry calls this an ecosystem in development. It's like buying a car without wheels and being told that some volunteers will come to put them on for you. The we'll fix it later culture saves companies costs and turns the user into a lifelong beta tester.
