I have a V3 WRT54G with the version 4 firmware. I tried to upgrade to Alchemy V1 twice using the web interface for firmware upgrades. Both times I ended up with the message "Upgrade are failed" in red on the screen. I used a wired connection. I even set it to half duplex/10M. The only way to revive it was to set an IP address of 192.168.1.50 on the computer with a mask of 255.255.255.0 and a gateway of 192.168.1.1 and run tftp. Took me a little while to figure that one out. So why did the upgrade fail on me?
