We have two MacBooks connecting wireless to two wired printers. Some time in the past two days, both MacBooks no longer see either printer using Bonjour. The Mac Mini on a wired connection is fine. So what changed on the router? And how do I change it back?
I posted the fix, but someone deleted it for some reason. Check out the end of this thread for a description of the fix:
I tried disabling IGMP proxy (based on multiple web search results) and that did not work. What finally did work was to turn off IGMP filtering (also in advanced settings under IGMP) for the printers.
