Hello.
I've got a problem after update.
My wifi connection process by NetworkManager is droped by timeout due to dhclient.

I've
03:00.0 Network controller: Qualcomm Atheros AR9462 Wireless Network Adapter (rev 01)

Static IP is worked fine. There is very strange situation.

I've added "dhcp=internal" string to /etc/NetworkManager/NetworkManager.conf to [main] block to change a
dhcp client. It solved the problem.

Good luck.
Nick
