From my Windows 10 PC on the LAN, I access the RT-AC88U router either by IP address (192.168.0.1) or by "router.asus.com".
This works, but ONLY as long as the router has a working WAN connection to the Internet in general.
But if I connect to the LAN, and the Wi-Fi shows "Connected, No Internet", I can still connect to other local devices like printers and NAS drives, but NOT the RT-AC88U Router Admin pages.
The only thing which displays is a blank page. There is no indication of errors in the Firefox browser console.
This concerns me, as I still want to be able to administer the router without a working Internet connection.
What configuration setting(s) in the router need changing for this to work?
