title: NanoKVM Static IP Fix
---
## Applicable Scenario
1. NanoKVM was configured with a static IP and can no longer obtain an IP address via DHCP.
## Cause
Some batches of NanoKVM were mistakenly configured at the factory with a static IP (`192.168.70.70`), which prevents normal DHCP address assignment.
## Fix Steps
Choose any one of the following methods based on your situation:
### Method 1: Reflash the firmware
Reflash the NanoKVM firmware to restore the default network configuration.
For detailed steps, refer to: [Flashing](https://wiki.sipeed.com/hardware/en/kvm/NanoKVM/system/flashing.html).
### Method 2: If the SD card can be removed easily
If it is convenient to remove the SD card, connect it to your computer with a card reader, then delete the `eth.nodhcp` file in the first partition of the SD card.
### Method 3: If the SD card is not easy to remove (e.g., Cube users)
1. Use a SIM pin or other pointed tool, insert it into the small round hole next to the USB-C port (this is the Reset button), and press down.
2. Keep holding the button, then connect the device to your computer using a USB cable.
3. Wait until a USB storage device appears on your computer. After the `boot` volume shows up, release the pin.
4. Delete the `eth.nodhcp` file in that partition.

title: NanoKVM 静态IP地址修复
---
## 适用情况
1. NanoKVM 被设置为静态 IP 后，无法通过 DHCP 自动获取地址。
## 问题原因
部分批次的 NanoKVM 出厂时被误配置为静态 IP（`192.168.70.70`），因此无法通过 DHCP 获取动态地址。
## 修复步骤
可根据实际情况选择以下任一方法：
### 方法 1：重新烧录固件
重新烧录 NanoKVM 固件，恢复默认网络配置。
具体操作可参考：[烧录系统](https://wiki.sipeed.com/hardware/zh/kvm/NanoKVM/system/flashing.html)。
### 方法 2：可方便拔出 SD 卡
若设备便于取出 SD 卡，可使用读卡器连接电脑，删除 SD 卡第一个分区中的 `eth.nodhcp` 文件。
### 方法 3：不方便拔出 SD 卡（如 Cube 用户）
1. 使用卡针等尖锐物体，插入 USB-C 接口旁的圆形小孔（该孔为 Reset 键）并向下按压。
2. 保持按压状态，同时使用 USB 线将设备连接到电脑。
3. 等待电脑识别出 U 盘设备；当 `boot` 盘符出现后，松开卡针。
4. 删除该分区中的 `eth.nodhcp` 文件。
