I have a WRT54GS v1.0 (CGN1********). It randomly decided to flash the Power LED, so I thought it was dead, and replaced it with a Buffalo WHR-HP-G54, but kept the Linksys. I got bored today, googled around, and found this place. I read the tutorial in the FAQ on how to reinstall the firmware, but got stuck. The guide is great, but then, i get this. 6. You may now proceed to upgrade the routerâ€™s firmware with the files that were downloaded. I do have the firmware downloaded and unzipped, but how exactly do I update the firmware? Thanks guys.
