I'm hoping someone here can offer some wisdom as to how to deal with a problem with my Netgear R7000. I've done the Google thing, plus searched this forum, and didn't come up with any solutions yet.
I've been running dd-wrt on the R7000 since June of this year, but as of yesterday the router has started rebooting approximately every two minutes.
Aside from occasional changes to the wireless settings I haven't changed any settings, etc., since setup 6 months ago.
The current firmware version is DD-WRT v24-sp2 (10/08/14) kongac
Are there any troubleshooting steps you can recommend? I've worked in IT for years, but routers and firmware are outside of my sweet spot. Looking for input from people with more experience.

Thanks!
Maybe nvram is messed up, first thing I'd try is to power on the unit, after 2 sec press and hold the reset button for 20s, you should see by the lights, that it reboots, after that nvram should be cleared. Now it either works again or you have some bigger problem which can only be checked if you attach a serial cable to it so you can see debug from the board.
The Peacock thread mentioned this as well, including a command to run that has been reported to fix the issue - but that command didn't help. Based on that I rejected the 2.4GHz issue as the cause ...
But right about the time of the original post I also turned off the SSID broadcast for the 2.4 interface, and the router stabilized. Which is weird, since we don't have any new wireless clients.
The Instructables link I referenced above mentions rolling back to an earlier build to try and avoid this problem. I'm currently on 25100M, but the article mentions using 24865M, or even going to 24345M to avoid the problem. I've even seen posts referencing 23900M
However, the Kong R7000 Best Practices thread mentions a newer build (Feb 2015) with better Broadcom drivers to address this - but doesn't mention the actual build number to look for.
So if my reboots are related to the 2.4GHz issue, and suddenly after 6 months one of our devices has decided not to play nicely with the router, what's the best build number to use?
PS: Activating the SSID broadcast on the 2.4GHz interface triggered the reboots again. By early process of elimination it looks like it's my Dropcam that's not behaving.
