Hacking the Linksys WRT54G

Posted by timothy on from the go-forth-and-multiply-them dept.

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."

    It's a dupe, was posted on friday. Still one of the better cringely columns...

      If you buy his "you can resell your DSL bandwidth" argument which in 90% of cases is not true.

      My TOS explicitly allows me to resell my bandwidth, heck, my ISP even has a page explaning what it is and how you can set it up.

      I read the internet for the articles.

    back to the roots: openwrt is much more fun!

    only a base system, which can be customized for your needs.

      It is a core system, very basic. On top of that you can install what you want with ipkg's.

      I have running:
      SSHd
      trafic shaping with iptroute2+tc
      custome firewall script
      no-ip client
      tcpdump
      network syslogd

      It doesn't run a webinterface (yes, to me that is an advantage.)

      Next on the agenda: vpn client to the office. ( so I am always connected from home.)
      serial interface so the nids can give instructions to the WRT.

      This is exactly what I need, from a 12watt machine (the WRT uses 12V DC, 1A) that makes 0 noice (no moving parts)

      And above all, it is a shiny fun geektoy :)

    Sveasoft isn't the only game in town (though it is one of the top ones). Others include:
    EWRT, from Portless Networks (a fork of Sveasoft)
    Wi-Fi Box

    Ahh... the wonders of OSS and GPL. :-)

    Ummmmm...it's GPL'd. They cannot put any restrictions on distribution other than those implied and expressed within the GPL itself (unless my understanding is incorrect). I am a paying Sveasoft subscriber, and all that gets me is access to the betas and pre-releases which aren't available to non-paying. Oh, and I can download the PDF manual.

  5. Hey, Not only Linksys guys! by zoobab · · Score: 5, Informative

    I would like to say that there is not only Linksys, but all Broadcom based routers (Trendnet TEW-411BRP, Belkin F5D7230, Motorola, Asustek wl300g et wl500g, Buffalo Airstation, Dell Truemobile2300).

    See:

    There is also the other APs based on Intersil:

    Personally, I run OpenWRT (http://openwrt.ksilebo.net/) on my WRT54G. In my opinion, it is better, and my contact with the developers so far on IRC has been wonderfull.

    Check it out, and a WRT54G (or the WRT54GS) is a nice investment, even if it was just for its geekyness :-)

  7. My impressions of various third-party firmware by Yeechang+Lee · · Score: 4, Informative
    (I've also posted this to wrt54g@yahoogroups.com and alt.internet.wireless.)

    I've had a WRT54g v2 since February, and have tried several third-party firmware offerings over the past few months. I have a Comcast 3000/256 cable modem connection, and have been 100% Linux at home for almost nine years. Here's my quick impressions of each:
    • Sveasoft Samadhi2 - Certainly the most famous alternative. Unfortunately I could *never* get, after repeated tries on multiple occasions, to get either the static DNS or bandwidth management, two of the three primary reasons for using a third-party to work. Static DNS (having the router's DNS server proffer the static DHCP settings as internal IP addresses for machines on my network) works for about 15-30 seconds after a reboot but then suddenly stops. Bandwidth management has never, ever worked for me (and, yes, I'm aware of the bug in at least one Sveasoft version in which the upload and download values got swapped). And of course there's that ridiculous bug that corrupts static DHCP entries. I have no interest in paying Sveasoft for later firmware versions in which I presume these features actually work as advertised; without restarting the disputes on the subject, I am very dubious about the legalities of what James Ewing is doing with GPL code.
    • Enterprise WRT 0.2 beta1 - Based on the Sveasoft Samadhi2 source code and also integrating the NoCatSplash authentication portal, which I don't need. Same results as with Samadhi2 regarding (non)functionality of bandwidth management or static DNS and the static DHCP bug.
    • OpenWRT b4 - Got errors in the compilation process (not the make not being able to find two tarfiles; I downloaded those manually) so used a binary I found online. Promising, and the package system is quite elegant, but the the lack of substantial documentation and (more important) the lack of a bandwidth management package also made it a nonstarter.
    • Wifi-Box 2.00.8.1pre6-i - The firmware I use now. Static DHCP and static DNS work right and work well. SNMP support is useful. No bandwidth management, but then it doesn't promise it or anything else it can't deliver. Having the source code on SourceForge offers at least the promise of future improvements by someone, if not the incommunicado-at-present author.
