I have no words. (#1438)

So apparently dnsConfig in Router was never set.
Router::networkConfig was set, but only used in the function
which set it and otherwise only passed to another function once.
dnsConfig was only used in one place.

both member variables have been removed in favor of just
referencing Router::m_Config.
