    Try... (from dd-wrt wiki)

    The Linksys site mentions 'Management Mode' which makes it trivial to recover from bad flashing. Here's how to do it:

    • Unplug the power cord from the back of the router.
    • Hold down the Reset button.
    • While holding down the Reset button, plug back in the power cord to the router.
    • Continue to hold the Reset button for five (5) seconds. After five (5) seconds, release the button.
    • Wait for about one (1) minute. Then, on a computer connected to the router, launch a web browser (for example, Internet Explorer or Mozilla Firefox).
    • Type in the router's IP address of into the Address field and press the [Enter] key.
    • The Management Mode - Firmware Upgrade interface should appear.


    Recovering with TFTP

    If pinging does not work, check the IP Address of your computer and make sure it is assigned an IP address in the subnet of the router IP. For simplicity sake you can assume "192.168.1.x" is good. If you do not have a good IP, the DHCP Server might not be working. So set your IP manually to something like with as your gateway and then try pinging the router again.

    Power the router on with a continuous ping running in a command window. You should see at least some seconds, at least 2-3 pings, where it responds to ping of address. Do this several times to be sure. If it does you have good chance of simple recovery. Especially if previous firmware set the boot_wait variable to on, the router pauses even longer than normal during bootup to accept a recovery flash. All you need to do is provide a firmware to it via TFTP during this window of time.

    Prepare your PC, firmware file and TFTP software and play with the timing of powering it on and starting the TFTP session just after applying power. If you try it a number of times (at least 10) you will probably rescue the router with no fuss!

    Microsoft Windows contains a TFTP client. With TFTP, all of the information about the transfer is specified during the initial setup; there is little client/server interaction as compared with standard FTP. To flash a router using Microsoft Windows, open a command prompt, change to the directory containing the firmware to upload (this example assumes the firmware file name is code.bin), and then enter the following command (assuming your router IP
