MAC discovery failure when enabling wake on lan

@DBMandrake - I had set dnsproxy=yes in /etc/connman.prefs in order to resolve some tethering issues. Could this be causing any of the MAC discovery and smb name resolution issues I seem to be experiencing with wake-on-lan?

I saw some other information (like here, for example) saying that DNS issues can sometimes lead to these types of problems. This reminded me that I had made the above DNS-related change.
