In my case, this happened shortly after the latest firmware from October 20th, 2025 was installed, and a hard factory reset via the WPS and power buttons had been performed. So for me, it showed up on a clean setup. It worked initially, and then quit shortly after the AWS issues. Also, my router was not hit by malware. I don't use AICloud, and all info that is known to be blank, or distorted with the malware infection, is correctly populated.Check you DHCP page in LAN settings. If you see some unknown devices in manual IP and your domain is set to asus.com, then you have this malware affecting quite a few. I had it on my AX86U Pro. Solved by applying latest firmware wand then factory reset.
You should not rely on the WPS reset or hard factory reset. It has been shown to not completely clear the settings on the AX86U. Might be a good idea to Factory Reset and Initialize from the GUI and after a reboot do the WPS reset. Then manually configure the router.In my case, this happened shortly after the latest firmware from October 20th, 2025 was installed, and a hard factory reset via the WPS and power buttons had been performed.

More likely a bug, or server side problem, or Asus finally decided to drop support for the RT-AX86U, and this is how they show it.
Thank you, I thought it was the other way around where the WPS method was the one that was reliable and the software one was not.You should not rely on the WPS reset or hard factory reset.
