As other have already pointed out you can connect to the other
interface, if possibile, or manually restart only one of them (e.g.
dhclient em0).
Also learn to use a tmux or similar and send more commands thru a
nohup to avoid that being disconnected keeps your commands unfinished.

Hope this helps.
