I just got a new ZyXEL (P-660HW-T1 v3) router/modem from my ISP. I have it conneced to a D-Link router. Both have active wireless. When I have my Mac Mini and MacBook Pro connected to the D-Link they have no problem seeing each other. I have sharing enabled on the Mini so it just appears in the sidebar of the MacBook without any hassle. When I switch both to the ZyXEL they don't see each other. Internet works but the local network shows up as empty on both. Do I have to enable something on the new router or what? Thanks for reading.
