I was having lots of issues with unexplained reboots and I found that the watchdog daemon was the cause of my reboots.

I disabled the watchdog and I've been up for 3.5 days as of this post.

I've just checked and it's disabled by default. Sadly, I'm afraid that your router will reboot sooner or later.

Today, mine lasted for more than 4 days and restarted. It's really driving me crazy right now, as the router has become pretty unreliable. I can't leave anything big downloading or copying for a while, because the router might randomly reset in 1 hour, 1 day, 2 days, etc.

Once again, I have an standard setup without anything fancy like QoS, Watchdog, VPN; anything like that.

If anybody can guide me on how to get a crashdump, I will provide it to Kong so it could help us all.

Please, let's all actively contribute in finding a solution to this thing.

Thanks again.

Just bumping this thread... any news? Kong? The router keeps resetting a couple of times per day, it's getting really, really annoying because it aborts all my automatic downloads (PlayStation 4, Wii U, file sharing sites, etc.) and I have to manually start them again or wait for their timeout to pass to allow me to redownload - probably halting again in the middle because of another router reset.

Could you please help me with this?

Thanks.

Well, here we have some "progress" Rolling Eyes. I've flashed 2016-07-04 3.0 30100M.bin and it's been up for three days and a half, until later today when it crashed, but it didn't actually restart like it always have.

What happened is that the WPS light stayed on, 1 LAN light was on too and another orange light also (can't see from down here; it's in the ceiling), but the wireless was off and there was no internet. I've left it in that state for more that 15 minutes to see what would happen and it did actually nothing, so I was afraid that the router was bricked again and that I would have to use my previous mod to TTL it back to life again... Shocked

I manually restarted it by turning off/on and it booted. It's been running so far (for 8 hours), but this is a new type of crash that never happened before this build; so far it always restarted once or more per day.

Kong, do you have any idea what's going on? Should I keep on trying the newer versions that you upload to your FTP often? I have them all downloaded in my disk.

Thanks.

I am on 30325 which only reboots every few days.

I did not have any fancy settings except 2 HD's attach to USB. I only changed wifi channels, nothing special.

BTW, I am not sure if it is hardware issue. I tried Tomato, it reboots as well. And its wifi signal is extremely weak, so I switch back to dd-wrt.

I'm on the similar Asus RT-AC3200 and so far 30370M has fixed my issues; that being said I only run it as a straight access point.

Hey folks I'm not here to cause trouble but after trying about 10 different builds of ddwrt over the past year or so and having a max uptime of 13 days I gave Shibby's Tomato a run on my R8000, and it's been up for 60 days now with 0 reboots. Not sure if it's because of different drivers or what but for those who need reliable uptimes there is that option. Wireless strength and speed have been solid as well.

Would love a stable ddwrt build on the R8000 but it just doesn't seem like a lot of us can achieve that unfortunately.

Happy Routing,

I was considering giving Tomato a try, but with how good the newest 30370M build has been I think I'll stick with that for now. Thanks for sharing your Tomato experience with me - now I feel even better about sticking with DD-WRT.

I installed Syslog Watch to try to debug my R8000 reboot issue. I have not seen R8000 reboot yet however I saw a lot of message like this:

8/14/2016 9:20:35.956PM 192.168.1.1 NETGEAR secur/auth Warning Aug 15 04:20:36 login[1711]: invalid password for 'UNKNOWN' on 'pts/0'

Someone is hacking my Router? Why IP is router itself? Anyone can help? Thanks in advance.

This message comes from telnetd, you have enabled wan telnet access and someone tries to logon. You will see this all the time, world wide login scans using standard user/passwords.

Thanks Kong for explanation. I guess the same, the only thing puzzled me is that it listed router address, so looks like that internal IP address is where it is being attached. Thanks.

Maybe it's a channel issue? I get same wifi reception across ddwrt and tomato (Shibby). I use ctf as well on tomato but still had fine signal strength without it.

I am pretty sure that's not the reason.

I spent a lot of time between Netgear/Kong/Shibby, make sure I used the same channel for all 3 bands, and same settings whenever I can. Kong version dd-wrt has similar (or very close) wifi result with Netgear, but read/write speed with attached HD is slower (18MB/12MB for read write compare to 28MB/18MB with Netgear from the same plac with the same laptop).

With Shibby Tomato, the wifi signal is so weak that my phone even drop the wifi signal when I was at the corner of 2nd floor, with Netgear/Kong built dd-wrt, I can stream bluray ISO without any issue at the same place.

I tried to adjust the Tx power from default 41mw to up to 200mw, and I don't see any difference, read/write speed to attached HD is also much slower (12MB/8MB).

Update:- Fixed it by adding a custom script (via GUI) to down vlan2, wait for 5s, and up vlan2.


DD-WRT v3.0-r29300M kongac (03/30/16)
DHCPv6 with PD

On reboot, i see that IPv6 address is allocated (from the DD-WRT GUI) first... Then after 1 or 2 minutes... i see IPv4 address gets allocated but IPv6 address is removed.... and i can only use IPv4...

If i do the following, then both IPv4 and IPv6 remain up...
- In GUI, disable IPv6 and re-enable IPv6

Is that fixed in later version?

Thanks
