Would you mind posting screenshots of the debug.htm and hidden_cpu.htm hidden pages for the RAX80?
The RAX80 is actually supposed to have dual quad-core CPUs:
"Nighthawk AX8 is powered by a 64-bit 1.8GHz quad-core processor designed to transfer multi-gigs of data with almost zero CPU load.An additional quad-core co-processor handles all Multi-Gig LAN-WAN traffic, ensuring the main processor is available for all otherapplications. Enjoy smoother Ultra-HD 4K video streaming and gaming without interruptions."
This can not only be found in their data sheet for the RAX80, but on the product website as well. It seems to not be a typo...
I know the R6700 shows four cores on the debug.htm hidden page although it only has a dual-core processor. Therefore, Netgear is also showing the status of its offload/co-processors in this particular scenario.
Here you go. Only the debug.htm page is found. The hidden_cpu.htm isn't found. Returns a 404.
