Flashing DD-WRT[edit]
![]() | For DD-WRT, These units seems to run more stable on the VINT builds. |
![]() | WARNING: Requires K2.4 for DD-WRT, Do not flash anything else! |
- Linksys WRT54G v3.1
- VINTage firmware. Details here.
- 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.
- 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.v24-15230_VINT_mini.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 or 30/30/30 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
