How-To: Setup IPv6 Connectivity using DD-WRT

I was bored. Plus it was planned long before anyway. [Why just now? It's either i have other things to do, or I had to let go of the completely-configured AP to deploy somewhere else.]

So here’s how i set-up an IPv6 connectivity using Tunnelbroker and a Linksys WRT54G running on DD-WRT firmware.

I. Setup an account in Hurricane Electric’s Tunnelbroker.

1. Signup for an account in TunnelBroker. Be ready to provide information, such as your valid email address. The password will be delivered to your email.
2. Once you have logged in, click “Create regular Tunnel” under User Functions in the left-hand side of the screen. NOTE: you can also create BGP tunnel (haven’t tried yet)
3. In the “Setup IPv6 Regular Tunnel” page, input your static public IPv4 address. Note that this should be reachable via icmp before it can be added.
4. Select the server closest to you. I chose Hong Kong. Then Submit.
5. Check the Tunnel Details for your newly created tunnel. You are allowed to create a maximum of 4 tunnels for your account.

DD-WRT now supports WRT54G2

Yay to all of us who’s been waiting for this forever! DD-WRT, my choice of 3rd party firmware, is now providing firmware for Linksys WRT54G2 (i.e. the newer Linksys router version in the market). This new version has additional checksums that made it harder to *hack.

The basic steps, as posted here courtesy of DD-WRT developer Eko, are as follows:

—— VxWorksPrep-G2V1 & VxWorksKiller-G2V1.bin ———

Get and install Linksys tftp.exe, set your PC to static IP, 192.168.1.10.

1. Reset the router to defaults on the Linksys Admin page, and let it reboot or manually reboot it after its finished.

2. Set your computer to a static IP address of 192.168.1.10 and 255.255.255.0 for a mask and plug ethernet cable into LAN port of the G2v1 unit.

3. Close all browser windows. Start Linksys’s tftp.exe utility, set IP to 192.168.1.1 and browse to the VxWorksPrep-G2V1.bin file, enter passowrd = admin, and click Upgrade. Wait 60 seconds for it to reboot on its own, if it does not, then powercycle the router manually.

4. Don’ open any browser windows. Again start Linksys’s tftp.exe utility, and browse to the VxWorksKiller-G2V1.bin file, enter passowrd = admin, and click Upgrade. Wait 2 min for it to reboot on its own, if it does not, then powercycle the router manually.

5. Tftp the DD-WRT firmware to the router, use “dd-wrt.v24-10709_NEWD_micro.bin” from the folder where you got these instructions; after sucessful tftp, wait 3 min for the router to finish writing new nvram deafults, etc… It should reboot on it’s own at least two times, so give it the 3 min and then goto http://192.168.1.1 (If it not reboots on its own, wait another 1 min, and then power cycle it)

6. When if finishes booting up…do a hard reset on the unit…let it boot again, and configure.

7. Don’t forget to set your computer back to automatically obtaining DHCP and DNS.

On normal occassion, i wouldn’t post steps when you can easily find it in the dd-wrt website. I’m just excited about this one (it also solves some of my problems), and can’t wait to try it on my own. Hmm, now where can i grab that UFO device?

Wifi Robot

This looks interesting.

Wifi Robot – A remote control car that can be driven over the internet or with a laptop wirelessly from up to 500m away. It has a live-feed network camera so that it can be driven without line of sight and a horn so that you can honk at people.

How-To: Debrick a WRT54G Router

This is a personal account of my de-bricking experience. Thanks to this forum post by Toxic.

I have this wireless router lying lazily in my work area for some 3 months now. I hate to admit it was all MY fault that it broke. It happened as I was about to configure it for deployment. I can’t remember the previous config, so i opted for reset. That’s when i can no longer access nor ping the device no matter how many resets i do. Well to be fair to me, this device has undergone two flashings (if such a word exists) though – an OpenWrt which almost bricked it and a DD-WRT which was stable – so that probably counts as probable cause for the bricking, right? *winks*

How-To: Crack Open a WRT54G Router

My main goal here is not exactly to just crack open a Linksys WRT54G. As a more noble reason, the real plan is to make an outdoor wireless using consumer-grade (read: cheap) readily-available access points to be used for one of my deployments.

If you are looking for a more descriptive or more technical how-to on the subject, this one from TechRepublic may be a better option. My post is more of a personal account of my achievement for the day — when i’m supposed to do VHDL and not this, haha! Plus, i’m not a good teacher, ain’t I? It’s also been years since i posted wireless stuff around here, it’s just time to break the ice.
