Question: I recently ported Luci to an OpenWrt router. I was just exploring the thing. I disabled the DHCP server on LAN and enabled as DHCP client. I saved and applied the configuration to the router. Now after a restart I am not able to connect the router webpage.

How do I enable the DHCP server again or can anyone let me know how to reset this OpenWrt router to default settings?

I tried in the serial port console. but I can't see any IP address for any interfaces. Before It was 192.168.1.1.

Please suggest...

Answer: 
You can run this command for making a factory reset:

```
killall dropbear uhttpd; sleep 1; mtd -r erase rootfs_data

```
If you enabled it as a DHCP client then your router should get an IP address from a DHCP server. If you connect your router on a net with a DHCP server you should reach your router's administrator page on the IP address assigned by the DHCP.
