How to resolve the issue of being unable to access the LAN interface after modifying the address in OpenWRT.

If you are unable to access OpenWrt by modifying the LAN port address, you can try the following troubleshooting methods:

1. Restart the router: Sometimes rebooting the device can resolve temporary network issues. Try turning off and restarting the router, then attempt to access the new LAN port address again.
2. To reset the router: If restarting does not work, you can try restoring the router to its factory settings. Usually, there is a physical reset button on the router that you can press and hold for a few seconds to reset it. Please note that this will erase all custom settings and restore it to the default settings.
3. Try using an alternative interface: If you are unable to access OpenWrt after changing the LAN port address, you can try using another interface on the router (such as the WAN port) to see if you can successfully connect. If you are able to connect successfully, you can then reconfigure the LAN port’s IP address and make sure that interface is connected to your computer or device.
4. To use recovery mode: Some routers have a feature called “Rescue Mode” that allows you to try to enter it to repair or reset the router’s configuration. The specific steps for entering recovery mode may vary depending on the router model, so please refer to your router’s documentation or official website for detailed instructions.

If the above methods do not work, you may need to reach out to your router manufacturer or the OpenWrt community for further assistance and support.
