Hi. My Asus router AX59U just got firmware update yesterday and both my Air and Mini dropped from internet.
The reason seems to be the guest network. For some reason, the computer is not connecting to the internet. If the guest network is not in use, everything seems to be working fine. As soon as the guest network is activated, the internet stops working. The computer does connect to the router but indicates that the internet is not available. All other devices seem to work well except Apple Air and Mini.
I reverted back to an earlier version myself, and everything seems to be working well.
For those with an ASUS router experiencing issues with the internet, check if your router got new firmware. I have already restored Air to factory settings once so you don't need to.
