it's possible, but I tried many cat6, and cat7 cables and they were all doing it. How long have you switched cables? I'd like to see if the reboot comes back after a little while. Like I said earlier, I thought my usb drive was the cause of my reboot. It was good for a short time after removing drive, but then reboots came back worse....
it’s been over a week.
I wasn’t having any issues at all for months (with the original cabling I used). but I relocated the router in September and used different cabling and that’s when the problems started. I cable managed and zip tied the ethernet cables together and that’s when the nightmare started. I don’t know if it was interference or what, but when I undid all that and used other cabling, it’s been stable for over a week.
The problem for me was definitely the 10 gbps port. Tried it with Aquantia, Intel (2.5 gbps and 1 gbps) and the router would crash under load. Repeatedly. I tried jumbo frames, decreasing the port speed, all to no avail. The 10 gbps crashed the router, period. But when I unplugged the cable from the 10 gbps port and plugged it into a 1 gbps lan port instead, there was no crashing under sustained load. I tried both the rj45 and sfp+ port and it crashed period. (As an aside, I’ve heard that 10gbps sfp+ to rj45 converters cause stability issues on other routers)
When the router was crashing, sometimes using a higher fan speed (medium or high) tended to help for a while, but even then sometimes it’d crash. Curiously, placing an external fan under the worked.
all in all, it seems that ASUS’s 10 gbps implementation is broken, and it’s better to just use a 10 gbps switch for 10 gbps ethernet. In fact, just for kicks and giggles, I tried a cheaper ax82u and it provides much better signal coverage (in the same channel) at 5Ghz than the Ax89x. I even got better wifi6 speeds (Speedtest.net) on my iPhone using the cheaper Broadcom-based ax82u than on the 89x. Very disappointing ordeal.
I returned the ax82u and am waiting on Wi-Fi 6E to hit the scene, and have learned a valuable lesson: Just because ‘reviews’ of an ASUS router are favorable doesn’t mean the router isn’t a piece of poo. The reviews dont tell you that signal coverage is worse than cheaper routers, or that the 89x outputs a 5ghz signal at a lower power than cheaper routers. They also don’t tell you about the 10 gbps port causing crashes. And ASUS’s tech support is atrocious. Completely bad.
But I got a managed 10 gbps switch, learned about vlans and link aggregation, port trunking, and all that cool jazz, and I’m quite happy with it. At this price point, we shouldn’t have these issues.
