Router Keeps Rebooting

I called support and their action actually worked.

Not sure which one it really is but I suspect more than likely its the reset to default step after installing updates. I saw mentions of that here and elsewhere. The docs and the update process do not mention it but it is buried in a PDF somewhere...not in the version that comes with the router. Its an unnecessary step that must be compensation for a bug, but it worked and is not too hard to handle...though since I autoupdate the firmware, I can assume it will happen again and will need to repeat when reboots resume.

Anyway the 2 steps I took were:

1. Direct connect power to the wall - removed from an older surge protector

2. After firmware updates, backup config. Then restore to factory settings, and restore config from the file. They say this should be done after every firmware...which sucks...and should get fixed.

I have been emailing logs to me every day since then (2 weeks now) and have not had a single unexpected reboot since - things are looking great.

The power thing seems suspect but I have seen other devices including the xbox one mention this as a probable cause of some issues. I suppose it is possible that the devices are more sensitive and/.or the power supply is less clean/consistent power...

But based on the fact that the problems seem to occur soon after an auto update of the firmware it seems the revert to factory settings step is the likely fix.

I had an issue about a week ago which required me to build the router. I used the reset factory, flash firmware, reset factory method. Since then the router will reboot every 4 days at ~6:30am. I dont think its a dirty power issue since the unit is connected to an APC UPS. I would like to replace it but it seems from previous posts the problem is firmware related. Any idea what I need to do to fix the issue... the router is driving me crazy with all problems.

I too have had numerous random router re-boots. Sometimes up to 10 times per day, then okay for a few hours and then another.
I contacted TS who told me all the normal things to try such as factory resetting etc. I did the 30-30-30 reset with the latest FW, (before and after) but it still happened.

One thing I am trying now is to turn off both up and down QOS which others have mentioned success with - we'll see.
Also disconnected my Magic Jack to see if that's the problem. It's only been 2 hours since I did this with no re-boots so far, so too early to tell but I will report back if things improve.

I think this problem has to do with ipv6 lease. If you cmd to find out when the lease expires, I bet the router will re-boot shortly after that time - mine does like clockwork.
I am trying to disable ipv6 to see if that changes.....

bflobills,

Interesting... I was looking at my cable modems (SB6141) setting last night and noticed the IP Mode was set to "IPV6 only".

I had a similar problem. Router would reboot frequently. At one point it was rebooting every 30 seconds. Tried resetting to factory settings and phone support requested I alter some of the advanced settings for WIreless and then reduce MTU. None of these worked. A search showed up that this problem is pretty common when certain devices connect to the 2.4Ghz wireless radio on the R7000 with both stock firmware and the open source versions. Testing showed I had several devices that caused it including Iphone 4s and Ipad V1. I returned the router as phone support just followed same script and advised that I should just return and get another unit. The forums seemed to suggest the issue was latest drivers provided by Broadcom for the chipset used in this and a number of other routers firmware. So the test of downgrading firmware to an old version seems like a good place to start. Shame support didn't believe me and kept advising it was hardware.

Its common - Check this thread on the subject - http://www.dd-wrt.com/phpBB2/viewtopic.php?p=944676&highlight=#944676

Hey guys my name is Tony. I'm having an issue where my netgear R8500 keeps power cycling and doesn't give me the chance to do anything with the firmware. Any advise? Going crazy over here.

I have found my r7000 cycles when I try to connect my laptop by wifi. Works fine with all other devices just goes out with laptop
