+Most routers have a feature for setting static IPs for devices. If you can easily access the router's management page, it's recommended to use this method.

 This ensures that NanoKVM always has a usable IP address, allowing network access to operate NanoKVM. If NanoKVM does not receive a valid IP address, you will need to manually modify the file on the TF card or reflash the image to use it normally.
