Hacking the Linksys WRT54G

knightrdr writes "Robert X. Cringely has posted an interesting article on the PBS web site about modifying the Linksys WRT54G wireless G broadband router to build a wireless layer on top of the Internet. He argues that with as little as a $70 investment per node, the Sveasoft WRT54G Firmware could be the first in a line of many wireless devices to enable a giant leap forward for the Internet."

  1. Interesting idea, but one small problem... by jimicus · · Score: 4, Interesting

    From the article, it seems that Cringely perceives this as being an idea which could put your local phone company out of business.

    Would this be the same local phone company which provides the ADSL link this would require?

      I, for one, would never trade the reliability of a landline for the boinkiness of a few consumer-grade WiFi router, tied to a (relatively) unreliable xDSL or cable net link, operating a best-effort protocol and managed by Joe Random.

      How much does a landline cost anyway when you strip out all the useless gadget (CID, call waiting, etc) ? 20$ ? 30$ ? How low can this rigged VoIP-over-WiFi thingy can go ?

  2. Damaging to Cisco proper, maybe...? by lvdrproject · · Score: 4, Interesting
    WISPs are a neat idea, but here's what i found interesting. If these routers provide the basic framework for you to build a Linux router upon, this means that any old Joe has the potential to build an advanced routing OS for this system. With enough toying around (and maybe this depends on Linksys adding in a hundred or two megs more of flash or something), it's possible eventually that somebody could write a Linux system for these cheap $50-to-$120 routers that will have similar functionality to Cisco's IOS, isn't it? I mean, they wouldn't be perfect replacements by any stretch of the imagination, but given a few simple and cheap hardware upgrades to the current routers (i imagine RAM and flash would be the biggest priorities), that type of stuff could really take off.

    I'm not alone here in being more interested in stuff like that than in WISPs, am i? A Cisco-like router (at least as far as the interface goes) for $70 or so would be awesome. :,)

    They can't put any restrictions on redistribution, but they can revoke your subscription at any time for any reason. Technically, they still have to provide the source to anything they provided you, but revoking your subscription means they don't have to provide you with any more updates.

    LinSpot for WRT54G will be launched soon.

    This means a WISP in a box for everyone - and LinSpot handles the roaming between all linspots and fills your PayPal account while you sleep (and while others roam).

    I guess it will take the LinSpot crew a couple of weeks to iron the bugs out and release this for your enjoyement.

  5. Numbers ?? by mcdade · · Score: 4, Interesting

    I would like to know where he gets the dollar values from at the bottom of the article? He starts to toss out how much money an access point will start to make but no real values to back it up.. come one.. you need some sort of proper accounting..

    Almost sounds like a get rich scam, look at how much money you can make by buying this device. Just like the gold rush, very few made money on gold, everyone got rich selling shovel's and supplies to the masses.. :)

    Another cringley article that is partially based on facts, partially on fiction..

  6. I'd be a lot more convinced to run one of these... by phearlez · · Score: 4, Interesting

    ... if a single damned one of the web pages gave me a good couple of concrete examples of what the payoff is of installing one of these alternatives. That is, beyond whatever disease makes so many linux users desperate to install linux on their toaster, pda and remote control. OpenWRT touts being small with a focus on installable packages, EWRT says what they have up on the others is the captive portal but none of them have an entry in their FAQ that answers "Why would I replace this currently functioning, rarely crashing pre-installed firmware and features with something else? Does it DO anything other than bragging rights at the geek pub?" And yes you troll, I know some have bandwidth shaping and other features but any software that purports to be a solution to a problem might want to identify that problem right off the bat or it should just call itself devTitsOnaBull.

  7. Sveasoft's interesting use of the GPL by aderusha · · Score: 4, Interesting

    The core firmware of these routers runs linux, and as such Linksys was compelled to offer the source code back to the community. Sveasoft was kind enough to modify the firmware using the provided source and to then provide compiled binaries and source back to the community.

    Now they've changed their model somewhat. Currently you can only download the binaries and source for the older versions of the firmware. To access any of their newer works, you have to pay them a $20/year subscription fee. Once you've ponied up the $20, you can download the new sources and binaries.

    While the GPL allows for this sort of action, it's their policing of it that makes me uncomfortable. You can download the code and binaries and post them on a website, but if they figure out which user did this they will cancel your subscription. If you post links in their forums to download sites for their new version your subscription is cancelled, your forum account suspended, and the post is deleted.

    What they've done is to take a GPL-covered firmware, improve it, charge $20 for access to it, and then do anything they can to censor any action of sharing that code. While their actions still obey the letter of the GPL, I can't really see that it is in keeping with the spirit of the free software movement.
