# Updating AuterionOS The AI Node utilizes the same update process as the Skynode, using `.auterionos` files. These update files can be uploaded to the AI Node via: * The web interface at when connected to the device via microUSB * The paired Skynode, as long as Skynode is aware of AI Node. This can be achieved by setting `NVIDIA_CONFIGURE_ETHERNET0_IP` on the AI Node to define a static IP address, and `NVIDIA_ETH_IP` on the Skynode to the AI Node's IP address. The AI Node exposes its update interface through the following subnets: * `10.41.2.0/24` (Default USB Debug subnet) * `10.41.3.0/24` * `172.20.0.0/16` (Default ETH0 subnet) * `10.223.0.0/16` Once a USB networking or Ethernet connection through one of the above mentioned subnets is established, the process of updating is the same as Skynode, and you can follow our [software update guide.](https://docs.auterion.com/vehicle-operation/settings-and-maintenance/skynode-software-update)
