Open the terminal from Applications menu -> Accessories -> Terminal run the following commands
service network-manager stop
rm /var/lib/NetworkManager/NetworkManager.state

Then reboot your system.

My first 15 minutes of experience with any linux was a networkmanager crash. it took me several hours of trying to cope with it myself (I thought that I’m doing something wrong), yet it seems that after n-teen years of development Linux still fails at simple tasks.
Thankfully it’s not my computer I set up linux on.
Anyways, back to the topic: neither the commands worked, nor the manual operation (the file cannot be edited or deleted, despite I made my account member of all possible groups). What’s up with that? I should have typed some more magic, maybe?
Eventually I’ve solved an issue by killing the process (Knetworkmanager, like if that K was necessary?) and suspending to disk. Hopefully one of the fixes that are currently being downloaded solves the issue. I just hope for it.

@mctom: the “more magic” is “sudo” before each command -
sudo service network-manager stop
… etc.
“sudo” runs the command as the root user, which is not the same (has more powers) even than making your user a member of all admin groups.
Maybe the OP is running always as root (!!!! gasp!) and didn’t think of sudo because of that.

1.) Check in file /etc/NetworkManager/nm-system-settings.conf and after [ifupdown] there should be managed=true (if false then change to true, otherwise network interfaces such as eth0 or wlan0 will have to be managed manually or by some other script)
2.) [at prompt type] sudo chmod 600 /etc/NetworkManager/system-connections/* (the files in this directory must be read-only by root only or NM will ignore them and there will be a log entry in /var/log/syslog if NM rejects due to “insecure configuration”
3.)[at prompt type] rm /var/lib/NetworkManager/NetworkManager.state (“rm” means “remove”, is like “del” in DOS, if that helps)
4.) [at prompt type]service network-manager restart
Viola! rebooting should not be required - It ain’t Windows.
