  3. Set a static IP on your computer to 192.168.1.7. Subnet mask should be 255.255.255.0.
  4. Connect the lan cable from your computer to a LAN port of your router. Make sure your router is plugged in. Nothing should be connected to your computer or the router except the lan cable between them. Turn your firewall and any wireless computer connections OFF.
  5. Power cycle the router (uplug the power from the router for 30 seconds and then plug it back in)
  6. Open your browser to 192.168.1.1 by putting that in the browser address window of your browser. You should open the linksys webgui and NOT a page that says Management Mode. If you see management mode, power cycle the router again.

  13. When you can access the dd-wrt webgui using a browser at 192.168.1.1, power cycle the router.
  14. When you can again access the dd-wrt webgui using a browser at 192.168.1.1, do another Hard reset or 30/30/30 on the router.
