v1 Hardware

This is the Wiki for v1 hardware, which has just "R6300" printed on the label on the bottom of the unit. Please do not get confused and try to use it on a v2 (R6300v2), which has a different CPU and is not covered here.

Flashing Instructions

It's always good practice to read the Peacock Thread for reference on Broadcom-based routers. It is an excellent historical reference that provides valuable insight on how these devices work and related processes/procedures.

Initial DD-WRT Installation

To go from stock Netgear firmware to DD-WRT on the R6300:

  1. Download initial flash (.CHK) firmware for R6300. Recommended: Kong K3-AC
  2. Reset router:
    1. Turn on router, wait for Power light to go solid green.
    2. Use end of straightened paper clip or similar object to press and hold Reset button on back of router for 20 seconds or until flashing of Power light signals router reset to factory default configuration.
    3. Release Reset button, and router should reboot with much flashing of lights.
    4. Wait for Power light to go solid green again.
  3. Disconnect PC from any network (wired or wireless).
  4. Connect PC Ethernet port to a router Ethernet port (not the yellow Internet port) with a cable, and wait for PC to be configured by router DHCP (which can take up to a full minute).
  5. Open Web browser and clear cache. (Initiate by holding down Shift and Ctrl while pressing Delete.)
  6. In Web browser, go to or
  7. Enter Netgear default username & password of "admin" & "password" respectively (no quotes).
  8. Click on Advanced > Administration > Router Update
  9. Browse to special .CHK file you downloaded in Step 1 above, and proceed.
    If you get a message stating the firmware you are loading is the same or older than the firmware on the unit, ignore the message, and load the .CHK firmware anyway.
  10. After router says it is done, wait until it has fully rebooted and the Power light has gone solid green again. (This may take several additional minutes.)
  11. In Web browser, go to and verify DD-WRT successfully installed.
  12. Reset router (as described above), and wait for Power light to go solid green again.
  13. In web browser, again go to and you should see the DD-WRT create password screen.
  14. Set a strong Password, Login, and configure DD-WRT.
