I don't know about Maxim, but waiting 20 seconds definitely doesn't
solve the problem for me. I've sometimes waited quite a long time after
rebooting before doing something that requires network access, and then
realizing that DNS is not working and that I forgot to go through the
disconnect+reconnect+test loop until it starts working.
