Updating your Avalon Nano 3S
The Nano 3S runs Canaan’s open-source Avalon_Nano3s firmware on the K230D platform, driving 12 A3197S chips. It reaches its web interface at the default IP 192.168.168.168; the factory login is admin / admin and forces a password change on first login. It broadcasts an AP-mode SSID like avalon_nano_XXXX and exposes the CGMiner API on TCP port 4028. Update it via the Avalon Remote / Avalon Family app, the web UI Upgrade page, or a signed .swu on the SWUpdate server at port 9090. Repo firmware artifacts run from 2025012122_b377540 through later builds such as 25061101 and 25103101. Match the firmware to the model, keep power and network stable, and verify the unit is hashing clean afterward. Full walkthrough: Avalon firmware update guide.
