WARNING: Requires VINT for DD-WRT, Do not flash anything else! |
WARNING: Requires K2.4 for DD-WRT, Do not flash anything else! |
Supported by dd-wrt as of = ?
- Read the peacock announcement found here: http://www.dd-wrt.com/phpBB2/viewtopic.php?t=51486
- Do a HARD reset 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.
- Leave the username blank and enter "admin" as the password
- Go to administration and firmware upgrade
- Navigate to the folder that you are using, and select dd-wrt.v24_mini_wrt54gs.bin
- Hit upgrade
- When you get a message that the upgrade is successful, wait FIVE FULL minutes before continuing.
- 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.
- When you can access the dd-wrt webgui using a browser at 192.168.1.1, power cycle the router.
- When you can again access the dd-wrt webgui using a browser at 192.168.1.1, do another HARD reset on the router.
- At this point you can choose to put a different build on, depending on what you needs are.
- Reset your computer ethernet connection to auto IP and auto DNS
- Check for recommended builds [[#Read the peacock announcement found here: http://www.dd-wrt.com/phpBB2/viewtopic.php?t=51486

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. |
On the OpenWrt Wiki
Support started version: 0.9
Current supported version: 22.03.5

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!

Notes
[comment added 3/23/08 by Bugman916] Just installed dd-wrt on my WRT54GS v2.0 router. I started with RC 6.2 dd-wrt.v24_mini_wrt54gs through the Linksys interface. Then I used the new dd-wrt mini interface to install RC6.2 dd-wrt.v24_std_generic. Everything seems "ok", I had no problems getting firmware installed. reminder Default login/pw .. root/admin
I had no trouble installing dd-wrt.v24_std_generic.bin onto my v2 WRT54GS. I didn't need to install mini first, didn't need to play with FTP, just installed it via the firmware update page. It worked without using the reset button.

[comment added 7/18/08 by koolkat] Does NOT need VxWorks killer to install due to the fact that factory firmware is linux based. Installed VINTage Mega firmware after installing VINTage standard, had no problems at all.
"[comment added 10/05/08 by mikeandmonika]" Installed DD-WRT v24-sp1 (07/26/08) mega-special (upgraded from HyperWRT through GUI). Upgrade took approximately 20 minutes to complete, but all is well and working great.
[comment added 12/20/08 by Corehop] Successfully installed dd-wrt.v24-9517_VINT_std.bin from factory linksys web GUI. Then tried upgrading to dd-wrt.v24-9517_VINT_mega.bin using the DDWRT web GUI, but when the router reset, it would not respond to pings and I had to short pins 15 and 16 on the flash chip and TFTP the Linksys firmware.
Comment galengish at 10:34 (EST) on 06 Jan 2009: I flashed a Linksys WRT54GS v2 router last night from original firmware to DD_WRT v24 (05/20/2008) std in one shot. This was performed via Internet Explorer and the Web GUI via Ethernet cable. The flash was successful on the first try and it is now successfully working as a client-bridge with another WRT54GS v7 running original Linksys firmware.
Comment Milkman at 8:47 (CST) on 26 Mar 2009: I just installed v24-sp1 mega from the Linksys firmware and it seems to have installed without a hitch, although I haven't had a chance to play around much yet. It is indicating "Error" on the title bar in my browser, but this may be associated with the lack of WAN connectivity for the router at this point. Will update should I find any significant errors/problems. (I hope I get the formatting correct here, please bear with me as I am new to wiki submissions)
Updated 10 Apr 2009: OK, backing up to v24 doesn't cause the "error" reporting on the browser (like in Электронный документооборот, seems to be something with the SP1 release. Haven't checked change logs, but seems very happy with v24 mega.
[comment added 3/22/2010 by geohey] I followed the flash instructions for WRT54GS v1.0 with no problems at all.
