I have a Linksys WRT54GS v7.2 and I have just flashed with vxworkskillerGSv7-v3.bin using these instructions:


http://www.dd-wrt.com/wiki/index.php/Linksys_WRT54GS_v7.0_%26_7.2

The problem is, my router is no longer listed in the available networks shown in the networks tab. How do I access the router with tftp so that I can load the micro firmware onto it?

I have attempted to use TFTP anyway - with the instructions in step 3:

Quote:
Enter "tftp -i 192.168.1.1 put dd-wrt.v24_micro_generic.bin" on your local Windows console and press enter.


however, without a connection to the router the attempt fails.

It does not state the smaller steps between flashing and tftp usage. Do you have a solution for how to connect with tfpt to my newly flashed router?

Does that mean you are trying to do this over wifi, and not a wired connection?

I have it connected via LAN right now, but I can't "see" the router. When I put in the 192.168.1.100 into TFTP it still fails.

Did you disable your wireless (just in case) and set your 1) IP address, 2) subnet mask, 3) default gateway and 4) DNS server on the computer's LAN, not WLAN adapter?

Also, you said that when you put in "192.168.1.100" if fails on TFTP. Shouldn't it be 192.168.1.1? Are you able to ping 192.168.1.1?

Thanks for the real reply. For the LAN vs WLAN adapter, I set the "Internet Protocol Version 4 (TCP/IPv4).

For the ping, I am confused as to how to ping a router that my network isn't seeing in the wifi list. When I plug in via LAN - I see "Unidentified".

Go back and repeat the last step that worked. You might have botched something. I don't know why you are preoccupied with a wireless signal. There is no firmware on your router. There will be no wireless anything. You can only do this with a cable. If you tried to do it any other way, you likely screwed things up rather badly.

Does the 75% loss ping mean that I bricked my router?

You have a 100% ping loss. What, exactly, did you do?

Try ping -t 192.168.1.1 and see if it gets steady.
