Network Manager Won't, Causing a Boot Problem

[wmichaelb]

I'm running Mint 13 with Mate. It takes several minutes to boot, during which I get error messages stating "configuring networking" and "60 seconds more to configure networking". Then it finishes booting, gives me an error message stating that the initiation is not complete, but runs anyway and gives me full access to the internet, so somehow it's working. But I want to fix the boot problem

The built-in ethernet connection in my mother board died, so I installed a Realtek NIC card. When I click on the Network Manager tray applet to force the boot to a specific MAC address, it states "NetworkManager is not running". If I right-click on the tray icon to start it, everything is greyed out except Edit Connections, and that dialog box is blank. I then click on Add, the next dialog box is again greyed out.

I've tried:

"sudo networkmanager"
"sudo networkmanager restart"
"sudo network-manager"
"sudo network-manager restart"

but I get an error message that states "no such command".

I've poked and prodded around in /etc/init and /etc/networking, but I can't find a text file that specifies the MAC address.
The services tab in the Control Center does not list Network Manager, so I can't turn it on there.
Running apt-get --reinstall install network-manager generates successful command-line activity, but doesn't fix the problem.

How can i get this beast to run? My system details are below:

Do I have to reinstall? Thanks in advance for any suggestions.

take a look at your /etc/network/interfaces file... if there is a mention of 'dhcp' in it, delete the 'dhcp' part in any of the interface's lines that you see (such as 'eth' or 'wlan'). I had experienced the same problem as you, until I discovered that dhcp was configured on one of my interfaces for some reason. As far as the Network Manager service goes, it's either sudo /etc/init.d/networking restart or sudo NetworkManager restart

shayamoonstone: I did find references to dhcp in the noted file, deleted those references and resaved the file. Using

sudo NetworkManager restart

did indeed restart the offending application. But when I rebooted, I still had the same boot problem. Since this is a test system with minimal data, I reinstalled, and the problem went away. What caused it, i don't know, but I have a well running system now.

Thanks for your time!
