It is a symlink. *ALL* symlinks have universal permissions. The real
permissions are those of the link target.

What's a "signal"? What do you mean?
When the machine awakes, it has to restart the network. Details differ
depending on what network setup you use, but if it is "automatic", ie,
dhcp, it certainly has to probe for a lease (new or renewed). And if
it is wireless, it has to restart it, check what access points are
available, choose one, and attempt to connect... Nothing strange
there. And there may be other activities, like clock sync, mail check,
browswers awakening and checking things, apper checking...
You would have to setup another machine with a sniffer to find out
exactly what network packages are goin in/out.
