The default plugin is decided by your distribution when building NetworkManager. That didn't change in 1.10 release. If such a change was done by your distribution and is unwanted, report a downstream bug. For example, Fedora didn't move away from dhclient, nor is it likely to do that any time soon. Because dhclient supports additional configuration from various locations like /etc/dhcp/dhclient.conf, and changing the default might break working installations on upgrade. Of course, that makes it problematic to ever change the default, which is a problem... On the other hand, if somebody relies on a particular DHCP plugin to be used, it might be resonable to require the user to explicitly configure it in NetworkManager.conf. This decision has to be made by your distribution. > As for the general issue of not properly working internal DHCP > client: > for me the only notable symptom is simple a timeout after 45sec when > waiting for an IP.

But there is not enough information in the logfile. Please consider providing a logfile with level=TRACE debug logging.
