Just out of curiosity, what mode is your router in, and is it behind a bridge?
normal wireless router mode.
http service stopped working again today so it seems to be quite frequent on beta 1 - however I am not sure if it is an issue specific to the beta.
It's tricky to work out what is happening as there is nothing in the log to indicate that the http service is crashed. If it happens again, I will run 'top' from the terminal to see if the httpd process is running...
