This is just not true at all. I agree unifi can be buggy at times, and their super clean interface means they need to hide stuff all over the place, but I havent found any network configuration I couldnt do on Unifi yet.

It’s unclear to me if it’s possible to significantly rethink the models to split those, but it seems that that is a minimal requirement to address the issue holistically.
