Cannot access E600 web GUI over wifi

It works fine over a wired LAN but due to the current configuration of the building this is extremely inconvenient. I could have sworn there was a setting somewhere that disabled GIU access via wifi, but a) I can’t find it anywhere now and b) I don’t think I ever would have enabled that.

I have an E400 accessible via wifi with no problems.

Why would the E600 web GUI be available via ethernet but not via wifi?

I figured it out after finding a note I’d made that confirmed the existence of the setting. Yes, there is a setting to disable wifi GUI access and yes, I must have enabled it at some point. It didn’t help that Google’s wretched AI was gaslighting me saying the setting never existed.
