I am trying to upgrade the firmware on this router but I can only do so wirelessly. I have already tried a lot of different firmware, but I really just want the stock linksys firmware outta there. I have already reset to factory and followed every step, but no matter what [firmware] I try, it just tells me update failed. and just goes back to normal like I never even tried. I have tried TFTP, but I have no luck with that. I have tried searching forums everywhere, but I haven't found any real guidelines or specifics for this since I either have to do this wirelessly, or live with linksys firmware eternally. Thanks.
