WRT54G V5: Bricked for good?

    I have a WRT54G V5 that is running DD-WRT V23 SP1 micro. It has been working fine until tonight. I noticed I had no link to my satellite modem, then also on my computers. I power cycled it and I get a blinking power light and all link/act lights (1-4 and Internet) are on solid. The power light does stop blinking after a little bit, 30 seconds maybe. Can not get a link to any device on any port.

    I tried holding reset while powering it on and still get the same thing.

    Is there anyway to recover this thing w/o a JTAG cable? WM might take it back, I've only had it 1.5 months and still have the box, manuals, etc... for it.

    Thanks,
    David

    Hey man, Had the same problem, Try to apply the Micro firmware with tftp software instantly as soon as your computer is direct connected to it... this must be done within 4-5 sec of power on...

    gl, timing is key.

    Used:

    DD-Wrt Micro Generic SP1
    Linksys TFTP.exe
    WRT54G and GS v. 5 and V. 6 (both models, with both version)

    Solution:

    TFTP Transfer Firmware onto bricked router during pre-boot sequence
    Pause until succesful, and give it a minute after Successful Upgrade

    Gl once again!

    Is there anyway this could work, because my computer constantly shows "Network cable unplugged".

    I'll give it a try. Thanks.

    Would you hapen to have a backup of the Flash, and a JTAG interface or serial connection?

    otherwise, because your computer cant even connect to it, its bricked.

    As Far As I see, its done for..

    Lucky for me Wal-Mart exchanged it for a V6. I flashed DD-WRT V23 SP1 micro on it and I'm back up and running.

    I need to build a JTAG cable for future use though. The diagrams look pretty simple. Just need to get the connector for the PC. Might have an old printer cable around somewhere.

    BTW, I was never able to get any response from the router following the instructions. I think it had serious issues, maybe a hardware failure of some sort.

    Thanks for the info.
