NCyclon - You're not alone. I'm on 378.52 and ever since the fw upgrade my F19805W is exhibiting the exact same problem. I power cycled everything today (AC68U and camera) and got it back for about ten minutes. I get the interface login but it times out or tells me to connection failed, try again later. I have The Dude network analyzer on my server and it reports ping and http is down on the camera. Asus FW interface sees it as connected. Ping requests to the camera time out. I also have three F18910W cameras indoors, and I lost the living room camera today. I power cycled that one twice and it's back up now. That outdoor cam just survived a record cold winter without a hiccup, so this was unusual to me. I Googled "Asus Merlin Foscam" and sure enough, here I am. Did you ever get this issue resolved? This started for me on 378.50. I would hate to have to roll back, or go with stock FW.
