This n66u was mistakenly flashed with latest ac66u firmware. It took the flash well and, while I didn't set it up, it appeared operational. I then tried to flash 374.43_49E4j9527 via web interface and ended up in boot loop. Since then I've tried 374.43_47EBj9527, big and mega DD-WRT releases, latest ASUS N66U release, along with two Tomato forks. It was the Tomato forks that actually got me a CFE(??) web interface @ 192.168.1.1. And that's where I've been stuck since. I can reboot and clear NVRAM from this interface, but firmware uploads changes nothing. I've only gotten ASUS' recovery utility to work twice, and it seems to flash completely, advising to wait for unit to reboot. I tried tftp with the various downloaded firmwares; it takes the flash after multiple attempts due to constant reboots, but nothing changes. Still have that CFE interface, but useless at this point. Only lights on router is steady power and connected LAN port. When flashing, LAN port remains lit, but Power light goes out. Looking for advice on how to proceed. TIA.
