ASUS RT-AC68U Keeps rebooting randomly on Merlin 376.47 Firmware

[waihonger]

Hey guys

I just bought an ASUS RT-AC68U Router recently, and the router was rebooting itself randomly.

I read that this was an issue with some of the older firmware, but even after updating to the latest firmware AND trying a bunch of different versions, the problem still hasn't gone away.

I've tried updating it to 374.43, 374.42, 374.41 and even 374.39.

I've also tried disable NAT Acceleration and IPV6 but the problem persists.

In our network configuration we've got a bunch of IP Pabx phones(grandstream) connected to a cloud provider, a switch, a wireless printer and a bunch of macs connected via wireless.

Does anyone have any ideas how I can troubleshoot this?

Cheers
Wai Hong

Enable persistent system log on the jffs partition and see if anything is in the log before the reboot.
Another reason may be surges or under/over-voltages which cause the device to reset itself. A voltage regulator or an UPS (at the least a line-interactive one with simulated sine wave) would address this.
