Sadly mine's not so rock solid, it started developing the red light of death syndrome (where it won't restart after a power outage until it has completely cooled off) after just three months.
Currently I've got it in pieces as I was trying to fit heatsinks to it. One on the BCM6358 helped a little, but the main culprit is the wifi, which is under 3 layers of steel shielding which I will probably have to desolder.
The firewall restarting issue which causes the connection to freeze at midnight occurred on mine on one of the previous firmwares, so it might not be the same thing, although as I recall, I did manage to find a fix, I think fiddling around with the schedule settings, but I don't remember exactly what I did.
Ah! I just found a post about it: I discovered that messing around with the schedule settings in a particular way corrupted the crontab entry used to restart the firewall so that it is skipped, curing the issue I had - I don't know if it works in the current firmware, but I posted about it in this thread :- http://forums.thinkbroadband.com/zen/f/3184832-load-...
Thinking about it, as I recall, the current firmware allows you to use the schedule feature to drop the wifi connection, as well as schedule firewall rules, so it probably is related, although there may be a separate crontab entry for dropping wifi, or they may be combined.
