Hi, I have a MacBook Pro with Mountain Lion installed, a Linux PC that serves as file server (using Netatalk), and a D-Link DIR-300 router. When all devices are connected via Ethernet, everything works fine. Hoverver, when i connect MacBook using WiFi, is cannot detect any services hosted by Linux box. I can connect by manually entering IP address in "Connect to server" window, though. The moment I plug ethernet cable, remote shares instantly show in Finder. However connected, both devices are in same network, ping each other etc. Can anyone help?
