RT-AC66 reboot on it's own

[mogulman]

Just had my RT-AC66 Router Reboot on it's own. Any way to find out why it rebooted?

The only thing I've done recently is updating my firmware to Merlin's newest version 376.45 2 days ago. Also I enabled IPV6 since Comcast is now saying they have it completely rolled out.

I haven't noticed anything else strange other than this reboot.

Going in the logs through the GUI, it only has stuff since the reboot.

Happened again last night. Going to try and disable ipv6 and see if that fixes it. Otherwise... Other option.. Go back to a previous FW or restore default firmware settings...

Any ideas what to try first?

Reboot

Try disabling HW Acceleration (LAN -> Switch Control -> NAT Acceleration).

I'm also on Comcast and ran into a similar issue. I've been running with HW acceleration off and the router's stayed up.

the logs been wiped on reboot is really dumb, I am amazed asus still havent fixed this.

I started putting my syslog on my usb stick and is a thread on here how to do it, but sadly when I last rebooted sometime last week I still lost the 5 days worth of log before the reboot so is still broken even using that workaround.

So far a little over a day with no reboot after just disabling IPV6.

4 days without a reboot now, with IPV6 turned off. I guess that must have been it.

For a more reliable confirmation, turn it back on to see if the problem returns...

Ok...It's been working since changing to IPv4 for 2 weeks. Trying IPV6 again right now. Let's see.

Same happening here. Will try turning off ipv6

Rebooted on its own last night. Definitely ipv6 causing it for me.

Did you try disabling HW acceleration as was previously recommended?

 

[mogulman]

Ok. Trying with hw acceleration disabled.

 

[mogulman]

So far seems good with hw acceleration disabled. Although I have a pretty fast wan connection, 120Mbps. Not sure if ipv6 does anything for me. Any reason that Ipv6 is more important than hw acceleration.

 

[mogulman]

.49 firmware still seems to have an issue with rebooting with acceleration turned on. FYI.

Having this issue in latest stock and .51 merlin. Stinks really, I want to utilize ipv6 but this router chokes without NAT acceleration when downloading anything at full speed (105 Mbps).

edit:

Contacted ASUS about this, their suggestion is to enable Jumbo Frames. Pretty sure this wont help, but I'll see if it fixes the crash.

yeah merlin may have seen my post on linksysforums (chrcoluk)

I only just came back to asuswrt-merlin because of CTF, at 70mbps my router was almost crashing, even the lan gui wasnt responsive, the software interrupts was completely flooding the cpu, so at 100+mbps you must have had singificant issues.

Now with CTF enabled, my cpu usage has plummeted when line is maxed out, and router stays responsive, but make sure you disable per ip traffic monitoring so CTF can work.
