How do I revert back to an OpenWrt router configuration

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

If you installed the SquashFS image you can run the script firstboot. That will return OpenWrt to the defaults of when you flashed the router.

With your serial access just run firstboot and then power cycle the device.

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

Some addition to previous comments   firstboot  won t be available until you run  mount root  command   So here is a full recap of what needs to be done  All manipulations I did on Windows nbsp 8 1    Enter Failsafe mode  hold the reset button on boot for a few seconds  Assign a static IP address  192 168 1 2  to your PC  Example of a command  netsh interface ip set address name  Ethernet  static 192 168 1 2 255 255 255 0 192 168 1 1 Connect to address 192 168 1 1 from telnet  I use PuTTY  and login password isn t required   Run  mount root   otherwise  firstboot  won t be available   Run  firstboot  to reset  Run  reboot -f  to reboot    Now you can enter to the router console from a browser  Also don t forget to return your PC from static to DHCP address assignment  Example  netsh interface ip set address name  Ethernet  source dhcp
