On Linux systems, you can set the timeout in /etc/resolv.conf, e.g.,

I'll admit that I'm not sure if those options are configurable on Mac and/or Windows workstations.
It was those showing problems.
Only 5 seconds isn't long enough that I would expect any problems. What do I need to put into the ifcf files or tell nmcli to set these options?
If you're using dhclient to manage addresses, then you can add the RES_OPTIONS variable to /etc/sysconfig/network:
# /etc/sysconfig/network RES_OPTIONS="timeout:2 rotate"
Or, with even less patience:
RES_OPTIONS="timeout:1 retries:1 rotate"
Grep for RES_OPTIONS in /sbin/dhclient-script for the gory details.
