Am I to understand you already did the following
Advanced -> Device discovery
Try enabling zero config [by clicking the word enable next to it.] then SAVE below it.
Or did apple just make an ass out of you by renaming something to their own language, that the rest of the world calls by its actual name?
"Bonjour is Apple's implementation of Zero configuration networking (Zeroconf), a group of technologies that includes service discovery, address assignment, and hostname resolution."
So, let me know if that fixes your "bug" or not.
