The Rockchip RK3229 is a legendary budget System-on-Chip (SoC) that has powered millions of entry-level Android TV boxes (such as the V88, MXQ 4K, and HK1 Mini) over the past several years. While its hardware is modest, many of these devices initially shipped with outdated firmware, often Android 6.0 or 7.1.
This is a driver mismatch. Open the box, look at the WiFi chip (e.g., SV6051p ). Search for RK3229 Android 9.0 SV6051p firmware . Alternatively, use a USB Ethernet adapter (which uses generic drivers). Rk3229 Android 9.0 Firmware
