    After multiple attemps using various procedures found on this forum, Thibors webpage, Hyperwrt and DD-wrt webpages, upgrading the firmware is never succeessful on my wrt54gs v1.

    Even though i get the message "upgrade successful", the power led flashes and I can't access the web gui. I then use the Linksys tftp app to flash a Linksys firmware back on to the unit, and then ping it. This is when the power led stops flashing and I can once again access the gui.

    Is there another way of upgrading the firmware on this unit. Any help will be appreciated.

    Mine is a 54GS v1.1

    Being a newbe to WiFi and Linksys routers, I was very reluctant to flash the DD-WRT firmware (v23 SP1), but finally got up the courage.

    Ran an Ethernet connection from the roof to the laptop (I normally run "all WiFi") and cleared the WRT (via web interface - I don't understand linux or Telnet!!)) to factory defaults. Then addressed the Home Page ( and entered "firmware upgrade".

    As advised by contributiors on this forum, loaded the DD-WRT v23 SP1 Final (Mini) and it all loaded just fine

    Then loaded the build that I wanted (DD-WRT v23 SP1 Final (VoIP) as that was the feature set that I was interested in) and let it reboot. (seems for some memory consideration, you have to load "mini" first before the "full")

    At this point the modem(satellite in my case) was disconnected. I edited the ISP settings (host, gateway, MAC clone, etc) and then powered up and reconnected the modem.

    Everything seems to be running well.

    Sorry I can't be more specific help, but that's how I did it with no problems

    before you upgrade what version of linksys firmware is installed on your router?

    what version of firmware thibor or ddwrt are you trying to upgrade to?

    have you hard reset the router?

    are you upgrading over wireless or ethernet cable?

    I'm upgrading over an ethernet cable and the router is running Linksys firmware v4.71.1.

    Thibor 15c and DDwrt v23 sp1 are the firmwares I've tried upgrading to with no luck.

    If by hard reset you mean holding the reset button for 30 seconds, then yes, I've tried it.

    have you used both the TFTP utility and the web gui to upgrade?

    How long after "upgrade successful" do you wait before moving on? It is recommended that you wait 5 to 10 minutes before you do anything. Then the first thing you do is a hard reset......hold the reset button for 30 seconds. You need to hold the reset button for 30 seconds just prior to flashing the updrade too. As soon as it's done booting from the hard reset, flash the upgrade. Too many people get impatient.

    I've only been using the web gui to upgrade the firmware.

    After the "upgrade successful" message appears, I've been waiting 5 minutes, and performing a hard reset only before the upgrade.

    I will try both suggestions.

    I finally figured it out...

    I first set the IP to, and the Subnet Mask to Then I performed a hard reset followed by upgrading the firmware through the web gui. This time, after the "upgrade successful" message, the power led was NOT flashing, but was on steady, so I performed one more hard reset.

    I can now access the web gui with the upgraded firmware, Thibor 15c.

    The help is much appreciated fellas
