Fun with WRT54G

9 posts in this topic

I may be setting myself up for some nasty responses here, but I'm looking to have some with my WRT54G Linksys Router. :)

I was thinking an asterisk box tied into nufone.net would be a good start.

Or FairuzaWRT from hackerpimps to play with Kismet Drone

Does anyone have some good stories to share of their fun with the WRT54G?

Just a fond memory of bricking mine and having to shot pins on the flash chip to get it so I could tftp back a working firmware. Fun. By the way, my understanding is that the newest WRT54GS not longer run Linux, so see if you can get one of the older GS routers if you want to run the firmware from HackerPimps. Did you watch their video from PhreakNIC? The file is:

2005-10-22 - Phreaknic 9 - 016 - Skydog, Qui-Gon, Sysmin - Wifi Panel.avi

and you can get it here:

Thanks Irongeek! I will check the video out later tonight.

Bad news about the new GS. I currently have a 54G, which only contains 4MB RAM. My understanding is Asterisk can be installed on the 4MB wrt54g but with great difficulty. The GS with 8 MB is recommended.

I thought I bricked my 54g a few times, but I found a trick that involved powercycling the router and waiting for an led to blink three times... (something like that..) Anyhow, I was luckly always able to TFTP my original settings back when I bricked....

Anyone else playing with their 54G?

From what I heard, only the newer WRT54G routers run something other than Linux. Pretty much every WRT54GS can run any GS-based firmware.

openwrt has it's own package manager, can run all kinds of stuff, kismet, dsniff, tcpdump, asterisk, irssi, whatever, and it stores stuff in nvram

Also I hear you can keep from bricking it pretty easy by turning on 'boot_wait' (explained in the openwrt documentation) that pauses 3 seconds before trying to boot the firmware, which gives you just enough time to tftp a working firmware back

I currently have OpenWRT on mine. It rocks. Thats about all I've done, is put different firmware on, I love openwrt though.

Use it as an access point, and then buy some more interesting networking equipment.

Sorry to bring up this old thread, but I thought this was useful. As most of you know, newer wrt54g and wrt54gs routers use VxWorks instead of Linux. Linksys offers a wrt54gl for moders that still runs Linux, but has less ram and flash for a higher price. The only way to be sure you are getting a wrt54g or wrt54gs is to look at the serial number, which luckily is on the outside of the retail package (if you order it online you would have to call them up and ask for this info) on a little sticker along with the MAC address. You can find which versions go with which serial numbers here:

I went by Sam's club last night and they had a bunch of ver 2 (s/n prefix CGN3) wrt54gs routers for about $60, and they should work fine for most of you Linux hacking functions. Check your firmware creators site to see which they support before you buy.
