I'll do that.

nmcli just says it's not connected. /var/log/messages appears to show a
DHCP problem (it sends a series of DISCOVER packets at increasing
intervals and then times out).

I've disabled iptables, ip6tables and SElinux as per MA Young's
suggestion and at first it worked. I then did a yum update and rebooted
(to a new kernel), and now the same sequence of actions doesn't work.

ifconfig shows the interface UP for IPv6 (although IPv6 is supposed to
be disabled) but not for IPv4 of course. It also shows a few hundred RX
packets, which could be DHCP replies I guess.

Finally, restarting NM does nothing, and ifup times out,
