DD-WRT Firmware: V23 SP2 Update
Posted on 11 Dec ’06 by Earl Moore
In previous posts I’ve described upgrading my Linksys WRT54G router to DD-WRT V23 Firmware (VPN Version), and later¬ upgrading to version DD-WRT V23 SP1. This past weekend I performed a further upgraded to DD-WRT V23 SP2. DD-WRT V23 SP2 consist of mainly error and bug fixes.¬ A copy of the change log that accompanies V23 SP2 can be found here.
The upgrade procedure was painless and took all of ten minutes. I used the following steps to upgrade from DD-WRT V23 SP1 to V23 SP2.
1. I downloaded the and unzipped the appropriate file from the DD-WRT site.
2. I saved a file of my routers current configuration settings to my local PC.
3. I reset the router configuration to it’s default factory settings.
4. I used the GUI interface to select the correct downloaded binary file and began the upgrade to the new V23 SP2 firmware. After the new firmware was loaded the router automatically reboots.
5. Using the GUI interface I reloaded my saved router configuration settings file. Again there was a reboot.
6. I tested to confirm a successful upgrade and configuration.

You’ll need to be sure and check the flashing notes that come with the firmware for any special instructions that may apply to your hardware.
I’ve been using DD-WRT as a replacement firmware in my LinkSys WRT router for some time now and have been very pleased with it’s feature set, reliability and user interface.¬ If your looking to give new life to a WRT router then I would highly recommend that you consider this firmware.
