Netgear R7800 reboots randomly under workload


I've set up my R7800 router with LEDE Reboot 17.01.1 r3316-7eb58cf109. Everything works OK, but sometimes the router reboots, when I surfer Internet.

How can I debug this issue?

I've found the reason.

My desktop computer was plugged into d-link switch with two internet cable, but lacp link aggregation was set up incorrectly, so a network loop might occure. When I browsed the Internet, some packages were looped, brought a huge network traffic, that caused the R7800 router to reboot.

After I corrected lacp link aggregation settings, the router stopped rebooting.
