WRT54G v1.1 dead after trying to update to Alchemy v1

    I just tried to update my 54G v1.1 router to Alchemy v1 and I got a message stating that the "upgrade failed". I read further on this forum that Linksys firmware v4.20.07 would not allow an upgrade file over 3MB, so I downloaded v2.02.7 and presumed to install it, then upgrade to Alchemy.

    However, when I re-connected my PC to the router and pointed a browser to it, I didn't get anything after the login prompt, just a blank screen. I then "reset" the router, but now the router does nothing but continually flash the power indicator 3 times.

    What do I do now?

    Recommend you follow usual "unbricking" procedures which are documented many places.

    Personally I connect to a switch first, then the WRT, and set to static IP 192.168.1.2. The use of the switch guarantees that I can hit go on the tftp session whenever I want. If you connect directly to LAN on WRT and use Windows, then you need to wait until Windows says "connected" on your ethernet interface which may already be too late.

    I would consider DD-WRT "mini" version, or OpenWRT or other firmware, Alchemy is quite old now.

    Don't worry it is recoverable, download this firmware wrt54g_1.42.2_fw.bin from here

    http://wireless.cisbg.com/soft/Linksys/

    You then have to tftp it into your router as described in hairdairymaids de-bricking article. Then you will be able to upgrade via the GUI

    The command you need in windows is this.

    start -> run -> cmd -> tftp -i 192.168.1.1 put c:\wrt54g_1.42.2_fw.bin

    One of the main things to understand it that when upgrading to DD-WRT you MUST use the generic version of DD-WRT if you wish to upgrade via the GUI all the other included files are for tftp only and will not work if you try to use then to upgrade via the GUI.

    If all that fails you can recover using jtag this is 100% guaranteed so long as there is no hardware faults.

    OK, updated to Alchemy v1, but...

    I did not see the last post until after I did the following:

    1. downloaded wrt54g_2.02.7_us_code.exe
    2. reinstalled firmware from command application
    3. after installation, I logged into router and all appeared to be up and functional

    Here is where I may have gone off the reservation:

    1. Opened browser session pointed at my router
    2. Went to Administrator|Upgreade firmware
    3. Updated firmware to Alchemy v1.
    4. Got the "Success" screen
    5. Closed browser session
    6. Opened new browser session to 192.168.1.1 and poof, nothing
    7. Tried pinging 192.168.1.1, nothing
    8. Tried a netstat, nothing

    Oh, but the router's power light did stopped blinking, that's a relief. <g>

    I have no idea what IP address this thing is using now. Where do I go from here.

    Well it should be using 192.168.1.1. I don't know why you can't ping it. Have you set your local area connection to the same subnet as the router and made sure that the local area connection default gateway is set to 192.168.1.1

    You could also try hard resetting the router with the reset button on the back doing this should make sure that the ip address is 192.168.1.1. Keep the reset button pressed until the power light led flickers and after this keeping the reset button pressed for a few more seconds, about 30 seconds in total should be enough.
