Flashing
![]() | NOTE: During configuration or flashing a device, the only things that should be hooked to the device is the computer and power. |
Flashing DD-WRT
![]() | NOTE: Resetting to factory defaults via reset button or mtd erase nvram is safe on this unit. |
![]() | For DD-WRT, These units seems to run more stable on the VINT builds.NEWD or VINT |
![]() | WARNING: Requires K2.4 for DD-WRT, Do not flash anything else! |
- Connected power and Ethernet cable to the router.
- 30-30-30 Hard Reset.
- Waited until lights returned to normal (longer is better).
- There is A LOT of WAITING. Cannot emphasize that enough. Waiting is the key. **
- Connected to http://192.168.1.1 using Internet Explorer.
- Logged in and flashed with dd-wrt.v24-13491_VINT_mini via the web interface.
- Waited until Upgrade Successful message and lights returned to normal (longer is better).
- Connected to http://192.168.1.1 using Internet Explorer and logged in to look around.
- Closed Internet Explorer.
- 30-30-30 Hard Reset.
- Waited until lights returned to normal (longer is better).
- Check for recommended builds here.
Flashing OpenWrt
![]() | This device is NOT RECOMMENDED for future use with OpenWrt due to low flash/ram. DO NOT BUY DEVICES WITH 4MB FLASH / 32MB RAM if you intend to flash an up-to-date and secure OpenWrt version onto it! See 4/32 warning for details. |
![]() | This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation. This means that even setting a password or changing simple network settings might not be possible any more, rendering the device effectively useless. See OpenWrt on 4/32 devices what you can do now. |
![]() | OpenWrt support for this device has ended in 2022. 19.07.10 was the last official build for 4/32 devices. |
![]() | Devices with Broadcom WiFi chipsets have limited OpenWrt supportability (due to limited FLOSS driver availability for Broadcom chips). Consider this when choosing a device to buy, or when deciding to flash OpenWrt on your device because it is listed as supported. See Broadcom WiFi for details. |

Upgrading
Updating DD-WRT
If dd-wrt is already on the router follow these instructions. If stock firmware is on the router follow the flashing instructions.
- Check for recommended builds here first.
- Set your computer to a static IP of 192.168.1.7. (or to whatever subnet the router is on) Disable all firewalls and security. Disable wireless on your computer and only have the router connected to the flashing computer by the ethernet cable between the two.
- Hard reset or 30/30/30 (If the router supports it, if not, reset to defults in the GUI) prior to flashing. Wait. Check for password page on re-login and change password.
- Flash firmware. You can use the webgui except if you have a belkin router. (For belkin use tftp.exe to flash)
- Wait...at least three minutes. Lights should return to normal. See important2, below. Failing to wait is how most people brick their routers.
- Do a power cycle of the router. (Unplug the cord, count to 30 and plug it back in.)
- Wait for the lights to return to normal usually about 2 minutes.
- Hard reset or 30/30/30 again (If the router supports it, if not, reset to defults in the GUI). Wait. Check for the password page and re-login to change the password. Then you can reconfigure your settings manually.
- Once configured set your computer back to autoIP and autoDNS.
Important1: This Hard reset or 30/30/30 works fine for Asus router, but you do have to power cycle after the reset.
Important2: After you flash the firmware, and before you do the hard reset, the router will be building some nvram settings. YOU MUST WAIT FOR THIS TO FINISH PRIOR TO DOING ANYTHING WITH THE ROUTER INCLUDING A HARD RESET. Usually, you can tell when this process is completed by the WAN light coming on, but it does take several minutes. Go have a beer. There are starting to be more and more people who BRICK their routers by not waiting until the nvram is rebuilt, PRIOR to doing a hard reset. YOU NEED TO WAIT!
Reverting
Reverting to OEM Firmware from DD-WRT
- Read the peacock announcement found here: http://www.dd-wrt.com/phpBB2/viewtopic.php?t=51486
- Do a Hard reset or 30/30/30 on the router according to note 1 of the peacock announcement (30/30/30)
- Set a static IP on your computer to 192.168.1.7. Subnet mask should be 255.255.255.0.
- 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.
- Power cycle the router (uplug the power from the router for 30 seconds and then plug it back in)
- 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.
- Enter your username and password
- Go to administration and firmware upgrade
- Navigate to the folder that you are using, and select WRT54GSv3_4.71.4.001_fw.bin.
- Hit upgrade
- When you get a success, wait FIVE FULL minutes.
- When you can again access the Linksys webgui using a browser at 192.168.1.1, do another Hard reset or 30/30/30 on the router.
- Reset your computer ethernet connection to auto IP and auto DNS

- Hard Reset (press for 30 secs the reset button - IMPORTANT).
- Upload the firmware from Linksys Web Interface.
- When finished the flashing, Hard Reset (press for 30 secs the reset button - IMPORTANT).

I tried to install the mega pack as well through the Linksys Web Interface. Did the resets even the 30-30-30 way, but it bricked my router. The power LED flashes fast and the DMZ sometimes comes up for about 5 seconds. When pinging TTL=100, but doesn't respond to the TFTP-tool anymore.
If it's safer to install the mini version first, you might want to do that first to take less chances...
