Have a vodafone router and a real ASUS router that does everything better, and I connect the vodafone router to it and then use the ASUS router for everything else.

Was debugging stuff and set it to AP mode - wanted to go back, but I couldn’t access the ASUS admin panel anymore at the usual 192.168.2.1.

It had a different IP, one I could find in the Vodafone router control panel, and through that found the ASUS router admin interface.
