    I always wanted to run a custom Linux firmware on a Linksys WRT54G, but when I went to several stores, all I saw on the box was the model number, not the version number. Some versions are compatible, others have different hardware and are not, but all the boxes look the same. This is rather strange considering most versions (presumably the free software compatible ones) already run Linux by default! Why don't companies proudly advertise the fact that they run Linux and that it is hackable? Those are useful features! The same goes for zipit [zipitwireless.com] wireless messengers. All run Linux, but the manufacture released a new version that cryptographically locks out the ability to load the device with a custom firmware, so you need to modify the hardware if you want to use these neat and inexpensive little computers as pocket web browsers, ssh clients, ogg players, or other cool things like that. By default they are only useful as an IM device. Why do companies go out of their way to stop their users from improving their own hardware and in the long run, doing free development work for the company? Why don't corporations want essentially unpaid dedicated employees?

    I also would love to have a media player that runs Rockbox [rockbox.org], but various hardware is in different stages of rockbox support. It seams like there would be a significant market for products that advertise the fact that they work with free software firmwares right on the box. It's a shame that many industries view "proprietary" as a feature, as something developed uniquely and innovatively by one company. Anything proprietary should instead be suspect of being buggy because there is no way for the public to verify it's security, it probably has poor support for open standards, and it's probably feature limited and uncustomizable.
    • You can tell the version by the model number...the information is on linksysinfo.org. But it's not too important, because any WRT54g you find in a brick-and-mortar store today is almost certainly version 5 or higher. These units use VMWorks which makes them cheaper to make because it uses less RAM and flash memory. Not that the price has come down, of course.

      However version 4 is not really gone: it's now called the WRT54GL, still runs Linux, will accept the third-party firmwares, and sells mostly via online

      Another poster has mentioned this, but you want the WRT54GL. I just helped a Co-worker buy one from NCIX.com and I flashed it with DD-WRT v.23 SP2.

      Yes, it costs more than the Vx-Works models, but then it does *SO* much more. Plus, the V1.1 model can be flashed directly with the latest version of DD-WRT, without having to take the intermediate step of flashing with DD-WRT Mini first.

      I am so impressed with mine, that I am considering buying two more. In all seriousness. (I can run Apache, Bittorrent etc on these things - and they consume far less power than a PC in doing so.)

      Buffalo WHR-G54S. Readily available in brick-and-mortar stores, supported by nearly every distribution that supports WRT54G variants, and cheaper than the mailorder-only GL.

      I got mine at Circuit City for $49. Rock solid and works great with DD-WRT.

  • I just bought a Linksys WRT54GL on Friday (it hasn't been delivered yet, though). Part of the decision was that this line of routers enjoys such wide use, seems to be very well supported on the Internet both with the regular and alternative firmwares. I plan on using either DD-WRT or Tomato (OpenWRT seems a little more complicated with less features, but the difference is probably not big). Apart from what the article says (obvious and few things), does anyone have any advice for me, things I need to look o

      I just got one a few weeks ago and replaced my WRT54G v6 with it. The same day I flashed to DD-WRT micro (they say you're supposed to start with that before upgrading the version you really want), and panicked because the web interface never game back. I did a reset on the router, and it's been running ever since. I was really impressed the other day when I upgraded to the VPN version of DD-WRT, and during the reboot I never even noticed an internet connection loss. Even MSN and AOL messengers stayed co
    • DD-WRT is great, I've been using it for a few years on an old Linksys WRT54G v1.1. I recently bought a new WRT54GL because I wanted to build a wireless bridge. I decided to make the new router my main router because it has a 200mhz processor versus my old 1.1 model which has a 125mhz processor. Both models have the same version of DD-WRT installed. I noticed a huge difference with the new WRT54GL, accessing the web interface is much faster and more responsive. My old router is now a wireless client/bridge

    OpenWRT wasn't very practical. It only worked on really old hardware that wasn't in stores anymore. Even then, you needed exactly the right serial number revision. The serial numbers that worked were made in small quantities and virtually impossible to find. Flashed a Linksys access point and bricked it. There was no JTAG or bootloader on the router to recover it.

    What's really needed is wireless router for desktop computers instead of attempts to reverse engineer Linksys routers just for the sake of being embedded.

      I've only flashed two Linksys routers with DD-WRT, but my experience couldn't be more different from yours... One is three years old, but the other is a six month old WRT54GL, and both still work like a charm.

  • The article doesn't mention QoS, for me this was the main reason I got the wrt54g and openwrt. You can put traffic control [lartc.org] on there and shape/limit the traffic going through. Together with the marking of packets from iptables this is a very powerful function only usually available on much more expensive kit.

    I used it so I could play FPS without latency problems when other users were on the LAN. It would also really help out for VoIP.

    I guess Linksys won't advertise this fact, which is a shame as it could mak
  • Well, because it isn't free I will probably get modded down for this, but I have messed around with stuff like OpenWRT on a Linksys and although it was kind of neat, what I would do is ditch the Linksys and run Mikrotik's RouterOS on a RouterBoard or similar hardware. I'm not saying it is perfect, but the RouterOS platform, which based on Linux, along with a custom-built CLI, is the most advanced of any software I have ever looked at for a wireless AP.

  • I'm always wondering why Linksys, or their OEMs, or anybody, don't sell a 'naked' router, or 'micro PC' that runs linux, and by default doesn't do much more. Developing and maintaining the firmware must cost them money, and they don't earn any money by including nagware (like Dell does), so these naked, no-firmware micro PCs should actually be cheaper than the real ones. But all i can find online which comes close to "a Linksys router without an OS, so go ahead and hack the hell out of it" would be stuff li
    • I'm always wondering why Linksys, or their OEMs, or anybody, don't sell a 'naked' router, or 'micro PC' that runs linux, and by default doesn't do much more.

      The answer is simple and the answer is always the same. The direct seller and big box retailer doesn't need and doesn't want the hobbyist. You build and ship for the profitable - predictable - mass-market sale.

  • There are routers that do not allow flashing a custom firmware: However, most devices do have bugs in the webinterface that allows the owner to execute arbitrary shell code to circumvent this protection. Often, there a different approaches: The routers given away by FON (La Fonera) did have some web interface vulnerabilities, however FON fixed this in the latest firmware (0.7.1-2). They did not pay attention to their chillispot system: There is an attack vector that involves spoofing the FON radius server,
  • This paper
    http://eprint.iacr.org/2006/086.pdf [iacr.org]
    includes a section on openwrt and basically claims that you shouldn't trust it to provide good random numbers (and hence good network crypto security) because it doesn't have any of the standard sources of entropy (keyboard, mouse, harddrive) that linux servers have. Of course, it will likely be no worse than the standard firmware but that isn't really the point here.
  • For all those who have a WRT, seriously, try this firmware instead. I switched ot it months ago and have not looked back:

    I have nothing bad to say about this firmware, at all.

    Some examples of its versatility:
