Flashing

Files needed:

  • (14289) [1] - For first time flashing only
  • (14289) [2]


  1. Do a Hard reset or 30/30/30 on the router
  2. Set a static IP on your computer to 192.168.1.7. Subnet mask should be 255.255.255.0.
  3. 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.
  4. Power cycle the router (uplug the power from the router for 30 seconds and then plug it back in)
  5. 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.
  6. Leave the username blank and enter "admin" as the password
  7. Go to administration and firmware upgrade
  8. Navigate to the folder that you are using, and select linksys-to-ddwrt-firmware.bin
  9. Hit upgrade
  10. When you get a success, wait FIVE FULL minutes.
  11. If you don't get success, repeat from steps 6 up to this one. If you still don't get success, clear your browser cache. Try using a different browser as well, to navigate to 192.168.1.1.
  12. When you can access the dd-wrt webgui using a browser at 192.168.1.1, power cycle the router.
  13. 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.
  14. Go to administration and firmware upgrade
  15. Navigate to the folder that you are using, and select wrt400n-firmware.bin
  16. Hit upgrade
  17. When you get a success, wait FIVE FULL minutes.
  18. At this point you can choose to put a different build on, depending on what your needs are.
  19. Reset your computer ethernet connection to auto IP and auto DNS
