Unable to see Elive PCs and vice-versa in Windows WiFi network

This is basically the same question as in the other topic.
For windows networks by "seeing" you mean "connecting" as undoubtedly you can "ping" the machines on the network. There's no such thing as Windows WiFi .... only standard WiFi.

To communicate with those poor Win machines, you'll have to stoop down and install and configure "samba" (the smb protocol they do understand)
