Network connections don't work after restart. 12.3 with Network Manager

Every time I restart my computer or connect to a different wifi network, I have to open a terminal, log in as root and run ‘dhclient’ to get my internet connection to work. This is the same for both interfaces on my laptop (eth0 and wlan0). NetworkManager is configured to use Auto/DHCP for all of my saved wifi connections. It’s just generally pretty annoying that it doesn’t work, so I’m here crying for help. Thanks!

did you update the system? I have two laptops with 12.3 and NetworkManager works fine.
Post your /var/log/NetworkManager (use SUSE Paste).
