    Well, I finally made the jump into the DSL world and figured I'd go ahead and get a router to wire my desktop and WiFi my laptop. I purchased the WRT54G from Newegg at a pretty good price.

    Here's the catch. It seems Linksys has made their firmware Open Source and there are some great things that people have been doing patching the Open Source Linux firmware. However, the newest version of this router (v5) no longer uses Linux, but something called Vxworks. It also has less RAM, so it's probably not capable of running the Linux firmware.

    What would you do? Should I just be happy if my new router works out of the box? Or should I return to NewEgg, swallow the restocking fee and find an older version of the router (or the newly re-branded WRT54GL) so that I can flash the firmware for these enhanced features (which, BTW, I don't fully understand yet)?

    Any thoughts?

    Look around. I picked up a WRT54G at MicroCenter two weeks ago and it was v4. They're still in the pipeline.
     
  4. I don't think the factory firmware was ever open source.I think some open source/Linux firmware was developed for it that replaced the factory firmware.Not all areas have Micro Center.A friend in Florida says there aren't any there.They do sell by internet though.
     
  5. How do you tell the difference between the older ones and the newer version?Is it the "L"?

    The first four characters of the S/N, which is visible on the outside of the box, should tell you.

    CDF0 = WRT54G v1.0
    CDF1 = WRT54G v1.0
    CDF2 = WRT54G v1.1
    CDF3 = WRT54G v1.1
    CDF5 = WRT54G v2.0
    CDF7 = WRT54G v2.2
    CDF8 = WRT54G v3.0
    CDF9 = WRT54G v3.1
    CDFA = WRT54G v4.0
    CDFB = WRT54G v5.0 (runs VxWorks, not Linux)

    I actually went out and found a v4 at WalMart last night for $49. I bought it figuring that I can always return it unopened if I decide not to pay the NewEgg restocking fee.

    You can tell the version by the Serial Number which is printed on the outside of the box, next to the UPC.

    And, according to this article Linksys had to release the firmware source due to the Linux GPL. In fact, go into the Linksys support section and click on "GPL Code Center" (http://www.linksys.com/servlet/Sate...836002&pagename=Linksys/Common/VisitorWrapper) and you can download the actual source of there firmware. I'm guessing that's why they stopped using Linux with v5.

    Thanks for the input.

  8. I doubt that's a reason they changed.Most likely an update in hardware.Thanks for the info.I was going to try one but I have some older PC's I made into routers for use at home.We don't have Wal-Mart here but there is a Micro Center not far so I might check on one.They used to be about $100 but I know everything has gotten cheaper.My "router" is a $3500 333Mhz Dell. ;f
