[edit] 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.

[edit] 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 It is an excellent historical reference that provides valuable insight on how these devices work and related processes/procedures.

[edit] Initial DD-WRT Installation

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

  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 http://192.168.1.1 or http://www.routerlogin.net
  7. At Configuring the Internet Connection select No, I want to configure the Internet connection myself., and proceed through the confirmation.
  8. Click on Advanced > Administration > Router Update
  9. Browse to Initial (.CHK) file you downloaded in Step 1 above, and proceed.
    If you get a message stating the firmware you are loading is older than the firmware in the unit, ignore the message, and load the firmware anyway.
  10. After router says it is done, wait until it has fully rebooted and Power light has gone solid green again.
    (This may take several additional minutes.)
  11. In Web browser, go to http://192.168.1.1 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 http://192.168.1.1 and you should see the DD-WRT create password screen.
  14. Set a strong Password, Login, and configure DD-WRT.

[edit] DD-WRT Upgrade

To upgrade the R6300 from DD-WRT to another version of DD-WRT:

  1. Download desired firmware for R6300. Recommended: Kong K3-AC 25015-SP1
  2. Reset router as described in Initial DD-WRT Installation.
  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 http://192.168.1.1 and login.
  7. Click on Administration > Firmware Upgrade
  8. Choose File to select firmware downloaded in Step 1 above, and proceed.
  9. After router says it is done, wait until it has fully rebooted and Power light has gone solid green again.
    (This may take several additional minutes.)
  10. In Web browser, go to http://192.168.1.1 and verify DD-WRT successfully upgraded.
  11. Reset router (as described above), and wait for Power light to go solid green again.
  12. In web browser, again go to http://192.168.1.1 and you should see the DD-WRT create password screen.
  13. Set a strong Password, Login, and configure DD-WRT.

[edit] Return to Stock

Flashing back to stock Netgear firmware is supported. Use the DD-WRT Web interface to upload Netgear firmware using the DD-WRT Upgrade procedure, and be sure to then reset the router as described in Initial DD-WRT Installation.

[edit] Build Information

Please note that majority of DDWRT builds are "beta" builds as development is ongoing. Official builds (Brainslayer builds) are made rarely (years apart as opposed to months for beta builds). In most cases beta builds have more fixes and are as stable as official releases. It is therefore recommended to use the latest beta build from the official FTP - ftp://ftp.dd-wrt.com/betas/

The following build has had no issues as of 2/24/2017 - ftp://ftp.dd-wrt.com/betas/2017/02-07-2017-r31277/netgear-r6300/

Kong Builds:

What makes Kong builds different from Brainslayer? See official Readme - http://desipro.de/ddwrt/Readme.txt

Kong no longer supports r6300v1 (only v2 support remains). Therefore below build is likely to be the last Kong build for r6300v1. Kong's changes get rolled into Brainslayer's builds and there is typically a new Brainslayer build every few weeks (above betas ftp link is to Brainslayer builds).

Kong build for this router (no longer recommended): Kong K3-AC 25015-SP1

[edit] Limitations

DDWRT does not support CTF (Cut Through Forwarding) which is required for Gigabit throughput on WAN port for this router. Internet speeds will be capped at around 110 to 120 Megabit. This is a non issue if your ISP providing you with 110 Megabit or slower internet. For anything faster you would have to switch to Tomato (http://tomato.groov.pl/?page_id=164) custom firmware or use Stock firmware to achieve Gigabit speeds on WAN side.
