DD-WRT Firmware: V23 SP2 Update

Posted on 11 Dec ’06 by Earl

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.
7. Finished

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.

    Hello Sir I want to setup a wireless modem router to connect the wireless network cameras, can u tell me which model and which company is better for me to purchase. And I need to cover minimum 30 meters range for each camera.

    And tell me how many Access Points we can connect to Wireless modem router with cable or without cable.

  3. Earl Moore 9 May ’07 at 2:22 pm

    Patan: That’s a tough question due to there being so many different variables involved.
    As far as network cameras if you are looking for good professional level camera’s I’ve had good experiences with “Axis Video Cameras”. They are not inexpensive. Also you can get cameras that have a build in web server so that you can monitor the video using any browser simply by selecting the video camera fixed IP address.
    As far as access numbers of access points and ranges it all depends upon the physical layout. A range of 30 meters is approaching the limit for most wireless access points so you may need additional access points to provide you the speed and coverage you want. There can be as many access points as you want or can afford. Without more detail I can make any better recommendations. Take care!

    What about EnGenius products – are they supported by DD-WRT? http://www.engeniustech.com – outdoor EOC 3220 EXT with existing Linksys Router that is already using your product.

    Matt,

    If they’re not on the list DD-WRT provided for compatibility I don’t know if they would be compatible or not. Sorry I can’t help.
