View Full Version : OpenWrt to DD-WRT flash problem

I was given a free WRT54G v3.0 (with the traditional burned out 12V
wall wart). After a futile effort trying to get the web interface to
appear, I decided to try SSH and found that it was running OpenWRT. No
web interface. Booting with the reset button depressed shoved it into
the "safe mode" which reset the IP address and password. I logged in
with telnet, turned on boot_wait, and saved the nvram. Ping still
works. So far, so good.

However, after that, I'm stuck. I've tried various ways to convince 3
different TFTP clients, on two different machines, to upload either
DD-WRT, the stock Linksys firmware image, or the latest OpenWRT image.
I even read the instructions on the OpenWRT web pile. Everything I
try results in a "timeout error". I've done TFTP firmware transplants
before, but I've never had this much trouble.

Anyone got a hint?

What I find irritating is I can't find the source but I have heard that
"overclocking" of the CPU can cause problems when it comes to trying to
do TFTP's.

Good point. I didn't check for overclocking. I would assume (famous
last words) that dumping the router into the safe mode with a reset
would return the clock and other settings back to the defaults, but
it's worth checking. I'll get back to it on Weds or Thurs. Thanks.
