Hi,
The kinds of schedules you are suggesting seem interesting to me. Although I had never contemplated severing the wireless according to multiple-times-schedules I am sure you are not alone in needing something like this.
Most folks just use the basic Start to Finish type of schedule. I am not sure if the kind of schedule(s) you need/want are available in any home type of router such as the DIR-655. I know I have overlapping access items, one covers website filtering, and the other covers access times.
As a workaround for the schedule thing, you may need to set up multiple access control policy items. If your LAN isn't that large, it shouldn't be too much of a hassle. Combine the multiple access policy items with multiple schedule items and you should be good to go....Not likely what you wanted, but it should get the job done....
As to the reboot bug... I can't say that I have seen it as I have only had the 1.33NA FW installed for about 24 hours now and if it happened to my router, I was asleep I suspect.
